PIC32MX1XX/2XX 28/36/44-PIN FAMILY 2.0 Note: 2.1 GUIDELINES FOR GETTING STARTED WITH 32-BIT MCUs This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the documents listed in the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). Basic Connection Requirements Getting started with the PIC32MX1XX/2XX 28/36/44pin Family of 32-bit Microcontrollers (MCUs) requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names, which must always be connected: * All VDD and VSS pins (see 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins, even if the ADC module is not used (see 2.2 "Decoupling Capacitors") * VCAP pin (see 2.3 "Capacitor on Internal Voltage Regulator (VCAP)") * MCLR pin (see 2.4 "Master Clear (MCLR) Pin") * PGECx/PGEDx pins, used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see 2.5 "ICSP Pins") * OSC1 and OSC2 pins, when external oscillator source is used (see 2.7 "External Oscillator Pins") The following pins may be required: * VREF+/VREF- pins - used when external voltage reference for the ADC module is implemented Note: The AVDD and AVSS pins must be connected, regardless of ADC use and the ADC voltage reference source. 2011-2018 Microchip Technology Inc. 2.2 Decoupling Capacitors The use of decoupling capacitors on power supply pins, such as VDD, VSS, AVDD and AVSS is required. See Figure 2-1. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: A value of 0.1 F (100 nF), 10-20V is recommended. The capacitor should be a low Equivalent Series Resistance (low-ESR) capacitor and have resonance frequency in the range of 20 MHz and higher. It is further recommended that ceramic capacitors be used. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended that the capacitors be placed on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within onequarter inch (6 mm) in length. * Handling high frequency noise: If the board is experiencing high frequency noise, upward of tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum thereby reducing PCB track inductance.

Note 1 5 4 2 3 6 Capacitor on Internal Voltage Regulator (VCAP) INTERNAL REGULATOR MODE A low-ESR (3 ohm) capacitor is required on the VCAP pin, which is used to stabilize the internal voltage regulator output. The VCAP pin must not be connected to VDD, and must have a CEFC capacitor, with at least a 6V rating, connected to ground. The type can be ceramic or tantalum. Refer to 30.0 "Electrical Characteristics" for additional information on CEFC specifications. 2.5 PGECx(3) PGEDx(3) VDD VSS NC 1: 470 R1 1 will limit any current flowing into MCLR from the external capacitor C, in the event of MCLR pin breakdown, due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS).

BULK CAPACITORS DS60001168K-page 28 device Place the components illustrated in Figure 2-2 within one-quarter inch (6 mm) from the MCLR pin. The use of a bulk capacitor is recommended to improve power supply stability. Typical values range from 4.7 F to 47 F. This capacitor should be located as close to the device as possible. 2.3 specific For example, as illustrated in Figure 2-2, it is recommended that the capacitor C, be isolated from the MCLR pin during programming and debugging operations. R 1 - -------------------- 2f C two Pulling The MCLR pin low generates a device Reset. Figure 2-2 illustrates a typical MCLR circuit. During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements.

It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. 2011-2018 Microchip Technology Inc. PIC32MX1XX/2XX 28/36/44-PIN FAMILY Pull-up resistors, series diodes and capacitors on the PGECx and PGEDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin input voltage high (VIH) and input low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGECx/PGEDx pins) programmed into the device matches the physical connections for the ICSP to MPLAB(R) ICD 3 or MPLAB REAL ICETM. The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is illustrated in Figure 2-3.

It is recommended to keep the trace length between the JTAG connector and the JTAG pins on the device as short as possible.

Guard Trace Guard Ring Main Oscillator 2.8 Unused I/Os Unused I/O pins should not be allowed to float as inputs. They can be configured as outputs and driven to a logic-low state. Alternatively, inputs can be reserved by connecting the pin to VSS through a 1k to 10k resistor and configuring the pin as an input. Pull-up resistors, series diodes and capacitors on the TMS, TDO, TDI and TCK pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin input voltage high (VIH) and input low (VIL) requirements. 2.7 External Oscillator Pins Many MCUs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to Section 8.0 "Oscillator Configuration" for details). 2011-2018 Microchip Technology Inc.

Circuit C The following tips are used to increase oscillator gain, (i.e., to increase peak-to-peak oscillator signal): Note: 2.8.1.1 Do not add excessive gain such that the oscillator signal is clipped, flat on top of the sine wave. If so, you need to reduce the gain or add a series resistor, RS, as shown in circuit "C" in Figure 2-4. Failure to do so will stress and age the crystal, which can result in an early failure. Adjust the gain to trim the max peak-to-peak to ~VDD-0.6V. When measuring the oscillator signal you must use a FET scope probe or a probe with 1.5 pF or the scope probe itself will unduly change the gain and peak-to-peak levels. C2 Typical XT/HS (4-25 MHz) C1 * Select a crystal with a lower "minimum" power drive rating * Select an crystal oscillator with a lower XTAL manufacturing "ESR" rating. * Add a parallel resistor across the crystal. The smaller the resistor value the greater the gain. It is recommended to stay in the range of 600k to 1M * C1 and C2 values also affect the gain of the oscillator. The lower the values, the higher the gain. * C2/C1 ratio also affects gain. To increase the gain, make C1 slightly smaller than C2, which will also help start-up performance.

Figure 2-7 illustrates a remote circuit using an independent power source that is powered while connected to a PIC32 non-5V tolerant circuit which is not powered. FIGURE 2-7: DS60001168K-page 32 REMOTE CIRCUIT WITH AN INDEPENDENT POWER SOURCE 2011-2018 Microchip Technology Inc. PIC32MX1XX/2XX 28/36/44-PIN FAMILY case, it is recommended that users can implement a digital or analog signal isolation, as shown in Figure 28. Without proper signal isolation on non-5V tolerant pins, the remote signal can power the PIC32 through the high side ESD protection diodes. This violates the maximum rating specification and can cause improper initialization of internal PIC32 logic circuits.

Voltages on these pins, if VDD < 2.3V, should not exceed roughly 3.2V relative to PIC32 VSS. At 3.6V or above, it will violate the absolute maximum specification and impact the device reliability. FIGURE 2-9: DS60001168K-page 34 If a remotely powered digital only signal can be guaranteed to always be 3.2V relative to PIC32 VSS, then a 5V-tolerant pin can be used without a digital isolator.

The following blocks are included with the core: * * * * * * * * Execution Unit Multiply/Divide Unit (MDU) System Control Coprocessor (CP0) Fixed Mapping Translation (FMT) Dual Internal Bus interfaces Power Management MIPS16e(R) Support Enhanced JTAG (EJTAG) Controller 3.2.1 EXECUTION UNIT The MIPS32 M4K processor core execution unit implements a load/store architecture with single-cycle ALU operations (logical, shift, add, subtract) and an autonomous multiply/divide unit. The core contains thirty-two 32-bit General Purpose Registers (GPRs) used for integer operations and address calculation. The register file consists of two read ports and one write port and is fully bypassed to minimize operation latency in the pipeline. The execution unit includes: * 32-bit adder used for calculating the data address * Address unit for calculating the next instruction address * Logic for branch determination and branch target address calculation * Load aligner * Bypass multiplexers used to avoid stalls when executing instruction streams where data producing instructions are followed closely by consumers of their results * Leading Zero/One detect unit for implementing the CLZ and CLO instructions * Arithmetic Logic Unit (ALU) for performing bitwise logical operations * Shifter and store aligner TABLE 3-1: MULTIPLY/DIVIDE UNIT (MDU) The MIPS32 M4K processor core includes a Multiply/Divide Unit (MDU) that contains a separate pipeline for multiply and divide operations. This pipeline operates in parallel with the Integer Unit (IU) pipeline and does not stall when the IU pipeline stalls. This allows MDU operations to be partially masked by system stalls and/or other integer unit instructions. The high-performance MDU consists of a 32x16 booth recoded multiplier, result/accumulation registers (HI and LO), a divide state machine, and the necessary multiplexers and control logic. The first number shown (`32' of 32x16) represents the rs operand. The second number (`16' of 32x16) represents the rt operand. The PIC32 core only checks the value of the latter (rt) operand to determine how many times the operation must pass through the multiplier. The 16x16 and 32x16 operations pass through the multiplier once. A 32x32 operation passes through the multiplier twice. The MDU supports execution of one 16x16 or 32x16 multiply operation every clock cycle; 32x32 multiply operations can be issued every other clock cycle. Appropriate interlocks are implemented to stall the issuance of back-to-back 32x32 multiply operations. The multiply operand size is automatically determined by logic built into the MDU. Divide operations are implemented with a simple 1 bit per clock iterative algorithm. An early-in detection checks the sign extension of the dividend (rs) operand. If rs is 8 bits wide, 23 iterations are skipped. For a 16-bit wide rs, 15 iterations are skipped and for a 24-bit wide rs, 7 iterations are skipped. Any attempt to issue a subsequent MDU instruction while a divide is still active causes an IU pipeline stall until the divide operation is completed. Table 3-1 lists the repeat rate (peak issue rate of cycles until the operation can be reissued) and latency (number of cycles until a result is available) for the PIC32 core multiply and divide instructions. The approximate latency and repeat rates are listed in terms of pipeline clocks.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY The MIPS architecture defines that the result of a multiply or divide operation be placed in the HI and LO registers. Using the Move-From-HI (MFHI) and MoveFrom-LO (MFLO) instructions, these values can be transferred to the General Purpose Register file. In addition to the HI/LO targeted operations, the MIPS32(R) architecture also defines a multiply instruction, MUL, which places the least significant results in the primary register file instead of the HI/LO register pair. By avoiding the explicit MFLO instruction required when using the LO register, and by supporting multiple destination registers, the throughput of multiply-intensive operations is increased. Two other instructions, Multiply-Add (MADD) and Multiply-Subtract (MSUB), are used to perform the multiply-accumulate and multiply-subtract operations. The MADD instruction multiplies two numbers and then TABLE 3-2: Register Number 0-6 7 adds the product to the current contents of the HI and LO registers. Similarly, the MSUB instruction multiplies two operands and then subtracts the product from the HI and LO registers. The MADD and MSUB operations are commonly used in DSP algorithms. 3.2.3 SYSTEM CONTROL COPROCESSOR (CP0) In the MIPS architecture, CP0 is responsible for the virtual-to-physical address translation, the exception control system, the processor's diagnostics capability, the operating modes (Kernel, User and Debug) and whether interrupts are enabled or disabled. Configuration information, such as presence of options like MIPS16e, is also available by accessing the CP0 registers, listed in Table 3-2.

The core is a static design that supports slowing or Halting the clocks, which reduces system power consumption during Idle periods. 3.3.1 INSTRUCTION-CONTROLLED POWER MANAGEMENT The mechanism for invoking Power-Down mode is through execution of the WAIT instruction. For more information on power management, see Section 26.0 "Power-Saving Features". DS60001168K-page 38 3.4 EJTAG Debug Support The MIPS M4K processor core provides an Enhanced JTAG (EJTAG) interface for use in the software debug of application and kernel code. In addition to standard User mode and Kernel modes of operation, the M4K core provides a Debug mode that is entered after a debug exception (derived from a hardware breakpoint, single-step exception, etc.) is taken and continues until a Debug Exception Return (DERET) instruction is executed. During this time, the processor executes the debug exception handler routine. The EJTAG interface operates through the Test Access Port (TAP), a serial communication port used for transferring test data in and out of the core. In addition to the standard JTAG instructions, special instructions defined in the EJTAG specification define which registers are selected and how they are used. 2011-2018 Microchip Technology Inc.

PIC32MX1XX/2XX 28/36/44-pin Family microcontrollers provide 4 GB unified virtual memory address space. All memory regions, including program, data memory, Special Function Registers (SFRs), and Configuration registers, reside in this address space at their respective unique addresses. The program and data memories can be optionally partitioned into user and kernel memories. In addition, the data memory can be made executable, allowing PIC32MX1XX/2XX 28/36/44-pin Family devices to execute from data memory. 4.1 PIC32MX1XX/2XX 28/36/44-pin Family Memory Layout PIC32MX1XX/2XX 28/36/44-pin Family microcontrollers implement two address schemes: virtual and physical. All hardware resources, such as program memory, data memory and peripherals, are located at their respective physical addresses. Virtual addresses are exclusively used by the CPU to fetch and execute instructions as well as access peripherals. Physical addresses are used by bus master peripherals, such as DMA and the Flash controller, that access memory independently of the CPU. The memory maps for the PIC32MX1XX/2XX 28/36/44-pin Family devices are illustrated in Figure 4-1 through Figure 4-6. Table 4-1 provides SFR memory map details.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 5.0 Note: FLASH PROGRAM MEMORY This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 5. "Flash Program Memory" (DS60001121), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). PIC32MX1XX/2XX 28/36/44-pin Family devices contain an internal Flash program memory for executing user code. There are three methods by which the user can program this memory: * Run-Time Self-Programming (RTSP) * EJTAG Programming * In-Circuit Serial ProgrammingTM (ICSPTM) 2011-2018 Microchip Technology Inc. RTSP is performed by software executing from either Flash or RAM memory. Information about RTSP techniques is available in Section 5. "Flash Program Memory" (DS60001121) in the "PIC32 Family Reference Manual". EJTAG is performed using the EJTAG port of the device and an EJTAG capable programmer. ICSP is performed using a serial data connection to the device and allows much faster programming times than RTSP. The EJTAG and ICSP methods are described in the "PIC32 Flash Programming Specification" (DS60001145), which can be downloaded from the Microchip web site. Note: The Flash page size on PIC32MX1XX/2XX 28/36/44-pin Family devices is 1 KB and the row size is 128 bytes (256 IW and 32 IW, respectively).

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 31. "Direct Memory Access (DMA) Controller" (DS60001117), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). The PIC32 Direct Memory Access (DMA) controller is a bus master module useful for data transfers between different devices without CPU intervention. The source and destination of a DMA transfer can be any of the memory mapped modules existent in the PIC32, such as Peripheral Bus devices: SPI, UART, PMP, etc., or memory itself. Figure 9-1 show a block diagram of the DMA Controller module. The DMA Controller module has the following key features: * Four identical channels, each featuring: - Auto-increment source and destination address registers - Source and destination pointers - Memory to memory and memory to peripheral transfers * Automatic word-size detection: - Transfer granularity, down to byte level - Bytes need not be word-aligned at source and destination FIGURE 9-1: DMA BLOCK DIAGRAM Interrupt Controller System IRQ Peripheral Bus Address Decoder * Fixed priority channel arbitration * Flexible DMA channel operating modes: - Manual (software) or automatic (interrupt) DMA requests - One-Shot or Auto-Repeat Block Transfer modes - Channel-to-channel chaining * Flexible DMA requests: - A DMA request can be selected from any of the peripheral interrupt sources - Each channel can select any (appropriate) observable interrupt as its DMA request source - A DMA transfer abort can be selected from any of the peripheral interrupt sources - Pattern (data) match transfer termination * Multiple DMA channel status interrupts: - DMA channel block transfer complete - Source empty or half empty - Destination full or half full - DMA transfer aborted due to an external event - Invalid DMA address generated * DMA debug support features: - Most recent address accessed by a DMA channel - Most recent DMA channel to transfer data * CRC Generation module: - CRC module can be assigned to any of the available channels - CRC module is highly configurable Channel 0 Control SE I0 L Channel 1 Control I1 Y Bus Interface Device Bus and Bus Arbitration I2 Global Control (DMACON) Channel n Control In L SE Channel Priority Arbitration 2011-2018 Microchip Technology Inc.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 10.0 Note: USB ON-THE-GO (OTG) This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 27. "USB On-TheGo (OTG)" (DS60001126), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). The Universal Serial Bus (USB) module contains analog and digital components to provide a USB 2.0 Full-Speed and Low-Speed embedded host, FullSpeed device or OTG implementation with a minimum of external components. This module in Host mode is intended for use as an embedded host and therefore does not implement a UHCI or OHCI controller. The USB module consists of the clock generator, the USB voltage comparators, the transceiver, the Serial Interface Engine (SIE), a dedicated USB DMA controller, pull-up and pull-down resistors, and the register interface. A block diagram of the PIC32 USB OTG module is presented in Figure 10-1. The PIC32 USB module includes the following features: * * * * * * * * * USB Full-Speed support for Host and Device Low-Speed Host support USB OTG support Integrated signaling resistors Integrated analog comparators for VBUS monitoring Integrated USB transceiver Transaction handshaking performed by hardware Endpoint buffering anywhere in system RAM Integrated DMA to access system RAM and Flash Note: The implementation and use of the USB specifications, as well as other third party specifications or technologies, may require licensing; including, but not limited to, USB Implementers Forum, Inc., also referred to as USB-IF (www.usb.org). The user is fully responsible for investigating and satisfying any applicable licensing obligations. The clock generator provides the 48 MHz clock required for USB Full-Speed and Low-Speed communication. The voltage comparators monitor the voltage on the VBUS pin to determine the state of the bus. The transceiver provides the analog translation between the USB bus and the digital logic. The SIE is a state machine that transfers data to and from the endpoint buffers and generates the hardware protocol for data transfers. The USB DMA controller transfers data between the data buffers in RAM and the SIE. The integrated pull-up and pull-down resistors eliminate the need for external signaling components. The register interface allows the CPU to configure and communicate with the module. 2011-2018 Microchip Technology Inc.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 11.0 These functions depend on which peripheral features are on the device. In general, when a peripheral is functioning, that pin may not be used as a general purpose I/O pin. I/O PORTS Note: This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 12. "I/O Ports" (DS60001120), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). Key features of this module include: * Individual output pin open-drain enable/disable * Individual input pin weak pull-up and pull-down * Monitor selective inputs and generate interrupt when change in pin state is detected * Operation during Sleep and Idle modes * Fast bit manipulation using CLR, SET, and INV registers Figure 11-1 illustrates a block diagram of a typical multiplexed I/O port. General purpose I/O pins are the simplest of peripherals. They allow the PIC(R) MCU to monitor and control other devices. To add flexibility and functionality, some pins are multiplexed with alternate functions.

DS60001168K-page 129 PIC32MX1XX/2XX 28/36/44-PIN FAMILY 11.1 Parallel I/O (PIO) Ports All port pins have 10 registers directly associated with their operation as digital I/O. The data direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx) read the latch. Writes to the latch write the latch. Reads from the port (PORTx) read the port pins, while writes to the port pins write the latch. 11.1.1 OPEN-DRAIN CONFIGURATION In addition to the PORTx, LATx, and TRISx registers for data control, some port pins can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Control register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs higher than VDD (e.g., 5V) on any desired 5Vtolerant pins by using external pull-up resistors. The maximum open-drain voltage allowed is the same as the maximum VIH specification. See the "Pin Diagrams" section for the available pins and their functionality. 11.1.2 CONFIGURING ANALOG AND DIGITAL PORT PINS The ANSELx register controls the operation of the analog port pins. The port pins that are to function as analog inputs must have their corresponding ANSEL and TRIS bits set. In order to use port pins for I/O functionality with digital modules, such as Timers, UARTs, etc., the corresponding ANSELx bit must be cleared. The ANSELx register has a default value of 0xFFFF; therefore, all pins that share analog functions are analog (not digital) by default. If the TRIS bit is cleared (output) while the ANSELx bit is set, the digital output level (VOH or VOL) is converted by an analog peripheral, such as the ADC module or Comparator module. When the PORT register is read, all pins configured as analog input channels are read as cleared (a low level). Pins configured as digital inputs do not convert an analog input. Analog levels on any pin defined as a digital input (including the ANx pins) can cause the input buffer to consume current that exceeds the device specifications. 11.1.3 11.1.4 INPUT CHANGE NOTIFICATION The input change notification function of the I/O ports allows the PIC32MX1XX/2XX 28/36/44-pin Family devices to generate interrupt requests to the processor in response to a change-of-state on selected input pins. This feature can detect input change-of-states even in Sleep mode, when the clocks are disabled. Every I/O port pin can be selected (enabled) for generating an interrupt request on a change-of-state. Five control registers are associated with the CN functionality of each I/O port. The CNENx registers contain the CN interrupt enable control bits for each of the input pins. Setting any of these bits enables a CN interrupt for the corresponding pins. The CNSTATx register indicates whether a change occurred on the corresponding pin since the last read of the PORTx bit. Each I/O pin also has a weak pull-up and a weak pull-down connected to it. The pull-ups act as a current source or sink source connected to the pin, and eliminate the need for external resistors when push-button or keypad devices are connected. The pull-ups and pull-downs are enabled separately using the CNPUx and the CNPDx registers, which contain the control bits for each of the pins. Setting any of the control bits enables the weak pull-ups and/or pull-downs for the corresponding pins. Note: Pull-ups and pull-downs on change notification pins should always be disabled when the port pin is configured as a digital output. An additional control register (CNCONx) is shown in Register 11-3. 11.2 CLR, SET and INV Registers Every I/O module register has a corresponding CLR (clear), SET (set) and INV (invert) register designed to provide fast atomic bit manipulations. As the name of the register implies, a value written to a SET, CLR or INV register effectively performs the implied operation, but only on the corresponding base register and only bits specified as `1' are modified. Bits specified as `0' are not modified. Reading SET, CLR and INV registers returns undefined values. To see the affects of a write operation to a SET, CLR, or INV register, the base register must be read. I/O PORT WRITE/READ TIMING One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically this instruction would be a NOP. DS60001168K-page 130 2011-2018 Microchip Technology Inc. PIC32MX1XX/2XX 28/36/44-PIN FAMILY 11.3 Peripheral Pin Select A major challenge in general purpose devices is providing the largest possible set of peripheral features while minimizing the conflict of features on I/O pins. The challenge is even greater on low pin-count devices. In an application where more than one peripheral needs to be assigned to a single pin, inconvenient workarounds in application code or a complete redesign may be the only option. The Peripheral Pin Select (PPS) configuration provides an alternative to these choices by enabling peripheral set selection and their placement on a wide range of I/O pins. By increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. The PPS configuration feature operates over a fixed subset of digital I/O pins. Users may independently map the input and/or output of most digital peripherals to these I/O pins. PPS is performed in software and generally does not require the device to be reprogrammed. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 11.3.1 AVAILABLE PINS The number of available pins is dependent on the particular device and its pin count. Pins that support the PPS feature include the designation "RPn" in their full pin designation, where "RP" designates a remappable peripheral and "n" is the remappable port number. 11.3.2 Priority is given regardless of the type of peripheral that is mapped. Remappable peripherals never take priority over any analog functions associated with the pin. 11.3.3 PPS features are controlled through two sets of SFRs: one to map peripheral inputs, and one to map outputs. Because they are separately controlled, a particular peripheral's input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. The association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on whether an input or output is being mapped. 11.3.4 INPUT MAPPING The inputs of the PPS options are mapped on the basis of the peripheral. That is, a control register associated with a peripheral dictates the pin it will be mapped to. The [pin name]R registers, where [pin name] refers to the peripheral pins listed in Table 11-1, are used to configure peripheral input mapping (see Register 11-1). Each register contains sets of 4 bit fields. Programming these bit fields with an appropriate value maps the RPn pin with the corresponding value to that peripheral. For any given device, the valid range of values for any bit field is shown in Table 11-1. For example, Figure 11-2 illustrates the remappable pin selection for the U1RX input. FIGURE 11-2: AVAILABLE PERIPHERALS The peripherals managed by the PPS are all digitalonly peripherals. These include general serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. CONTROLLING PERIPHERAL PIN SELECT REMAPPABLE INPUT EXAMPLE FOR U1RX U1RXR<3:0> 0 RPA2 1 In comparison, some digital-only peripheral modules are never included in the PPS feature. This is because the peripheral's function requires special I/O circuitry on a specific port and cannot be easily connected to multiple pins. These modules include I2C among others. A similar requirement excludes all modules with analog inputs, such as the Analog-to-Digital Converter (ADC). RPB6 A key difference between remappable and non-remappable peripherals is that remappable peripherals are not associated with a default I/O pin. The peripheral must always be assigned to a specific I/O pin before it can be used. In contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. RPn 2 RPA4 U1RX input to peripheral n Note: For input only, PPS functionality does not have priority over TRISx settings. Therefore, when configuring RPn pin for input, the corresponding bit in the TRISx register must also be configured for input (set to `1'). When a remappable peripheral is active on a given I/O pin, it takes priority over all other digital I/O and digital communication peripherals associated with the pin. 2011-2018 Microchip Technology Inc.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 11.3.5 OUTPUT MAPPING 11.3.6.1 In contrast to inputs, the outputs of the PPS options are mapped on the basis of the pin. In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPnR registers (Register 11-2) are used to control output mapping. Like the [pin name]R registers, each register contains sets of 4 bit fields. The value of the bit field corresponds to one of the peripherals, and that peripheral's output is mapped to the pin (see Table 11-2 and Figure 11-3). A null output is associated with the output register reset value of `0'. This is done to ensure that remappable outputs remain disconnected from all output pins by default. FIGURE 11-3: EXAMPLE OF MULTIPLEXING OF REMAPPABLE OUTPUT FOR RPA0 RPA0R<3:0> Default U1TX Output U1RTS Output 0 1 2 RPA0 Output Data Control Register Lock Sequence Under normal operation, writes to the RPnR and [pin name]R registers are not allowed. Attempted writes appear to execute normally, but the contents of the registers remain unchanged. To change these registers, they must be unlocked in hardware. The register lock is controlled by the Configuration bit, IOLOCK (CFGCON<13>). Setting IOLOCK prevents writes to the control registers; clearing IOLOCK allows writes. To set or clear the IOLOCK bit, an unlock sequence must be executed. Refer to Section 6. "Oscillator" (DS60001112) in the "PIC32 Family Reference Manual" for details. 11.3.6.2 Configuration Bit Select Lock As an additional level of safety, the device can be configured to prevent more than one write session to the RPnR and [pin name]R registers. The Configuration bit, IOL1WAY (DEVCFG3<29>), blocks the IOLOCK bit from being cleared after it has been set once. If IOLOCK remains set, the register unlock procedure does not execute, and the PPS control registers cannot be written to. The only way to clear the bit and reenable peripheral remapping is to perform a device Reset. In the default (unprogrammed) state, IOL1WAY is set, restricting users to one write session. 14 15 11.3.6 CONTROLLING CONFIGURATION CHANGES Because peripheral remapping can be changed during run time, some restrictions on peripheral remapping are needed to prevent accidental configuration changes. PIC32 devices include two features to prevent alterations to the peripheral map: * Control register lock sequence * Configuration bit select lock 2011-2018 Microchip Technology Inc.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 15.0 Note: * Prescaler capture event modes: - Capture timer value on every 4th rising edge of input at ICx pin - Capture timer value on every 16th rising edge of input at ICx pin INPUT CAPTURE This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 15. "Input Capture" (DS60001122), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). Each input capture channel can select between one of two 16-bit timers (Timer2 or Timer3) for the time base, or two 16-bit timers (Timer2 and Timer3) together to form a 32-bit timer. The selected timer can use either an internal or external clock. Other operational features include: * Device wake-up from capture pin during Sleep and Idle modes * Interrupt on input capture event * 4-word FIFO buffer for capture values (interrupt optionally generated after 1, 2, 3, or 4 buffer locations are filled) * Input capture can also be used to provide additional sources of external interrupts The Input Capture module is useful in applications requiring frequency (period) and pulse measurement. The Input Capture module captures the 16-bit or 32-bit value of the selected Time Base registers when an event occurs at the ICx pin. The following events cause capture events: * Simple capture event modes: - Capture timer value on every rising and falling edge of input at ICx pin - Capture timer value on every edge (rising and falling) - Capture timer value on every edge (rising and falling), specified edge first.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 18.0 Note: INTER-INTEGRATED CIRCUIT (I2C) This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 24. "InterIntegrated Circuit (I2C)" (DS60001116), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). 2011-2018 Microchip Technology Inc. The I2C module provides complete hardware support for both Slave and Multi-Master modes of the I2C serial communication standard. Figure 18-1 illustrates the I2C module block diagram. Each I2C module has a 2-pin interface: the SCLx pin is clock and the SDAx pin is data. Each I2C module offers the following key features: * I2C interface supporting both master and slave operation * I2C Slave mode supports 7-bit and 10-bit addressing * I2C Master mode supports 7-bit and 10-bit addressing * I2C port allows bidirectional transfers between master and slaves * Serial clock synchronization for the I2C port can be used as a handshake mechanism to suspend and resume serial transfer (SCLREL control) * I2C supports multi-master operation; detects bus collision and arbitrates accordingly * Provides support for address bit masking DS60001168K-page 175 PIC32MX1XX/2XX 28/36/44-PIN FAMILY FIGURE 18-1: I2C BLOCK DIAGRAM Internal Data Bus I2CxRCV Read SCLx Shift Clock I2CxRSR LSB SDAx Address Match Match Detect Write I2CxMSK Write Read I2CxADD Read Start and Stop bit Detect Write Start and Stop bit Generation Control Logic I2CxSTAT Collision Detect Read Write I2CxCON Acknowledge Generation Read Clock Stretching Write I2CxTRN LSB Read Shift Clock Reload Control BRG Down Counter Write I2CxBRG Read PBCLK DS60001168K-page 176 2011-2018 Microchip Technology Inc.

"Charge Time Measurement Unit (CTMU)" (DS60001167), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). Note: The Charge Time Measurement Unit (CTMU) is a flexible analog module that has a configurable current source with a digital configuration circuit built around it. The CTMU can be used for differential time measurement between pulse sources and can be used for generating an asynchronous pulse. By working with other on-chip analog modules, the CTMU can be used for high resolution time measurement, measure capacitance, measure relative changes in capacitance or generate output pulses with a specific time delay.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 26.0 Note: POWER-SAVING FEATURES This data sheet summarizes the features of the PIC32MX1XX/2XX 28/36/44-pin Family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 10. "PowerSaving Features" (DS60001130), which is available from the Documentation > Reference Manual section of the Microchip PIC32 web site (www.microchip.com/pic32). This section describes power-saving features for the PIC32MX1XX/2XX 28/36/44-pin Family. The PIC32 devices offer a total of nine methods and modes, organized into two categories, that allow the user to balance power consumption with device performance. In all of the methods and modes described in this section, power-saving is controlled by software. 26.1 Power Saving with CPU Running When the CPU is running, power consumption can be controlled by reducing the CPU clock frequency, lowering the PBCLK and by individually disabling modules. These methods are grouped into the following categories: * FRC Run mode: the CPU is clocked from the FRC clock source with or without postscalers * LPRC Run mode: the CPU is clocked from the LPRC clock source * SOSC Run mode: the CPU is clocked from the SOSC clock source In addition, the Peripheral Bus Scaling mode is available where peripherals are clocked at the programmable fraction of the CPU clock (SYSCLK). 26.2 CPU Halted Methods The device supports two power-saving modes, Sleep and Idle, both of which Halt the clock to the CPU. These modes operate with all clock sources, as follows: * POSC Idle mode: the system clock is derived from the POSC. The system clock source continues to operate. Peripherals continue to operate, but can optionally be individually disabled. * FRC Idle mode: the system clock is derived from the FRC with or without postscalers. Peripherals continue to operate, but can optionally be individually disabled. * SOSC Idle mode: the system clock is derived from the SOSC. Peripherals continue to operate, but can optionally be individually disabled. 2011-2018 Microchip Technology Inc. * LPRC Idle mode: the system clock is derived from the LPRC. Peripherals continue to operate, but can optionally be individually disabled. This is the lowest power mode for the device with a clock running. * Sleep mode: the CPU, the system clock source and any peripherals that operate from the system clock source are Halted. Some peripherals can operate in Sleep using specific clock sources. This is the lowest power mode for the device. 26.3 Power-Saving Operation Peripherals and the CPU can be Halted or disabled to further reduce power consumption. 26.3.1 SLEEP MODE Sleep mode has the lowest power consumption of the device power-saving operating modes. The CPU and most peripherals are Halted. Select peripherals can continue to operate in Sleep mode and can be used to wake the device from Sleep. See the individual peripheral module sections for descriptions of behavior in Sleep. Sleep mode includes the following characteristics: * The CPU is halted * The system clock source is typically shutdown. See Section 26.3.3 "Peripheral Bus Scaling Method" for specific information. * There can be a wake-up delay based on the oscillator selection * The Fail-Safe Clock Monitor (FSCM) does not operate during Sleep mode * The BOR circuit remains operative during Sleep mode * The WDT, if enabled, is not automatically cleared prior to entering Sleep mode * Some peripherals can continue to operate at limited functionality in Sleep mode. These peripherals include I/O pins that detect a change in the input signal, WDT, ADC, UART and peripherals that use an external clock input or the internal LPRC oscillator (e.g., RTCC, Timer1 and Input Capture). * I/O pins continue to sink or source current in the same manner as they do when the device is not in Sleep * The USB module can override the disabling of the Posc or FRC. Refer to the USB section for specific details. * Modules can be individually disabled by software prior to entering Sleep in order to further reduce consumption DS60001168K-page 235 PIC32MX1XX/2XX 28/36/44-PIN FAMILY The processor will exit, or `wake-up', from Sleep on one of the following events: * On any interrupt from an enabled source that is operating in Sleep. The interrupt priority must be greater than the current CPU priority. * On any form of device Reset * On a WDT time-out If the interrupt priority is lower than or equal to the current priority, the CPU will remain Halted, but the PBCLK will start running and the device will enter into Idle mode. 26.3.2 IDLE MODE In Idle mode, the CPU is Halted but the System Clock (SYSCLK) source is still enabled. This allows peripherals to continue operation when the CPU is Halted. Peripherals can be individually configured to Halt when entering Idle by setting their respective SIDL bit. Latency, when exiting Idle mode, is very low due to the CPU oscillator source remaining active. Note 1: Changing the PBCLK divider ratio requires recalculation of peripheral timing. For example, assume the UART is configured for 9600 baud with a PB clock ratio of 1:1 and a POSC of 8 MHz. When the PB clock divisor of 1:2 is used, the input frequency to the baud clock is cut in half; therefore, the baud rate is reduced to 1/2 its former value. Due to numeric truncation in calculations (such as the baud rate divisor), the actual baud rate may be a tiny percentage different than expected. For this reason, any timing calculation required for a peripheral should be performed with the new PB clock frequency instead of scaling the previous value based on a change in the PB divisor ratio. 2: Oscillator start-up and PLL lock delays are applied when switching to a clock source that was disabled and that uses a crystal and/or the PLL. For example, assume the clock source is switched from POSC to LPRC just prior to entering Sleep in order to save power. No oscillator startup delay would be applied when exiting Idle. However, when switching back to POSC, the appropriate PLL and/or oscillator start-up/lock delays would be applied. DS60001168K-page 236 The device enters Idle mode when the SLPEN (OSCCON<4>) bit is clear and a WAIT instruction is executed. The processor will wake or exit from Idle mode on the following events: * On any interrupt event for which the interrupt source is enabled. The priority of the interrupt event must be greater than the current priority of the CPU. If the priority of the interrupt event is lower than or equal to current priority of the CPU, the CPU will remain Halted and the device will remain in Idle mode. * On any form of device Reset * On a WDT time-out interrupt 26.3.3 PERIPHERAL BUS SCALING METHOD Most of the peripherals on the device are clocked using the PBCLK. The Peripheral Bus can be scaled relative to the SYSCLK to minimize the dynamic power consumed by the peripherals. The PBCLK divisor is controlled by PBDIV<1:0> (OSCCON<20:19>), allowing SYSCLK to PBCLK ratios of 1:1, 1:2, 1:4 and 1:8. All peripherals using PBCLK are affected when the divisor is changed. Peripherals such as the USB, Interrupt Controller, DMA, and the bus matrix are clocked directly from SYSCLK. As a result, they are not affected by PBCLK divisor changes. Changing the PBCLK divisor affects: * The CPU to peripheral access latency. The CPU has to wait for next PBCLK edge for a read to complete. In 1:8 mode, this results in a latency of one to seven SYSCLKs. * The power consumption of the peripherals. Power consumption is directly proportional to the frequency at which the peripherals are clocked. The greater the divisor, the lower the power consumed by the peripherals. To minimize dynamic power, the PB divisor should be chosen to run the peripherals at the lowest frequency that provides acceptable system performance. When selecting a PBCLK divider, peripheral clock requirements, such as baud rate accuracy, should be taken into account. For example, the UART peripheral may not be able to achieve all baud rate values at some PBCLK divider depending on the SYSCLK value. 2011-2018 Microchip Technology Inc. PIC32MX1XX/2XX 28/36/44-PIN FAMILY 26.4 To disable a peripheral, the associated PMDx bit must be set to `1'. To enable a peripheral, the associated PMDx bit must be cleared (default). See Table 26-1 for more information. Peripheral Module Disable The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled using the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers do not have effect and read values are invalid. TABLE 26-1: Note: Disabling a peripheral module while it's ON bit is set, may result in undefined behavior. The ON bit for the associated peripheral module must be cleared prior to disable a module via the PMDx bits.

The module must not be busy after clearing the associated ON bit and prior to setting the USBMD bit. 2011-2018 Microchip Technology Inc. DS60001168K-page 237 PIC32MX1XX/2XX 28/36/44-PIN FAMILY 26.4.1 CONTROLLING CONFIGURATION CHANGES Because peripherals can be disabled during run time, some restrictions on disabling peripherals are needed to prevent accidental configuration changes. PIC32 devices include two features to prevent alterations to enabled or disabled peripherals: * Control register lock sequence * Configuration bit select lock 26.4.1.1 Control Register Lock Under normal operation, writes to the PMDx registers are not allowed. Attempted writes appear to execute normally, but the contents of the registers remain unchanged. To change these registers, they must be unlocked in hardware. The register lock is controlled by the Configuration bit, PMDLOCK (CFGCON<12>). Setting PMDLOCK prevents writes to the control registers; clearing PMDLOCK allows writes. To set or clear PMDLOCK, an unlock sequence must be executed. Refer to Section 6. "Oscillator" (DS60001112) in the "PIC32 Family Reference Manual" for details. 26.4.1.2 Configuration Bit Select Lock As an additional level of safety, the device can be configured to prevent more than one write session to the PMDx registers. The Configuration bit, PMDL1WAY (DEVCFG3<28>), blocks the PMDLOCK bit from being cleared after it has been set once. If PMDLOCK remains set, the register unlock procedure does not execute, and the peripheral pin select control registers cannot be written to. The only way to clear the bit and re-enable PMD functionality is to perform a device Reset. DS60001168K-page 238 2011-2018 Microchip Technology Inc.

To simplify system designs, most devices in the PIC32MX1XX/2XX 28/36/44-pin Family family incorporate an on-chip regulator providing the required core logic voltage from VDD. A low-ESR capacitor (such as tantalum) must be connected to the VCAP pin (see Figure 27-1). This helps to maintain the stability of the regulator. The recommended value for the filter capacitor is provided in Section 30.1 "DC Characteristics". It is important that the low-ESR capacitor is placed as close as possible to the VCAP pin. Note: 27.3.1 ON-CHIP REGULATOR AND POR It takes a fixed delay for the on-chip regulator to generate an output. During this time, designated as TPU, code execution is disabled. TPU is applied every time the device resumes operation after any power-down, including Sleep mode. 27.3.2 27.4 Programming and Diagnostics PIC32MX1XX/2XX 28/36/44-pin Family devices provide a complete range of programming and diagnostic features that can increase the flexibility of any application using them. These features allow system designers to include: * Simplified field programmability using two-wire In-Circuit Serial ProgrammingTM (ICSPTM) interfaces * Debugging using ICSP * Programming and debugging capabilities using the EJTAG extension of JTAG * JTAG boundary scan testing for device and board diagnostics PIC32 devices incorporate two programming and diagnostic modules, and a trace controller, that provide a range of functions to the application developer. Figure 27-2 illustrates a block diagram of programming, debugging, and trace ports. FIGURE 27-2: BLOCK DIAGRAM OF PROGRAMMING, DEBUGGING AND TRACE PORTS ON-CHIP REGULATOR AND BOR PIC32MX1XX/2XX 28/36/44-pin Family devices also have a simple brown-out capability. If the voltage supplied to the regulator is inadequate to maintain a regulated level, the regulator Reset circuitry will generate a Brown-out Reset. This event is captured by the BOR flag bit (RCON<1>). The brown-out voltage levels are specific in Section 30.1 "DC Characteristics".

Refer to Section 30.1 "DC Characteristics" for the full operating ranges of VDD. It is important that the low-ESR capacitor is placed as close as possible to the VCAP pin. The typical voltage on the VCAP pin is 1.8V. DS60001168K-page 252 2011-2018 Microchip Technology Inc.

DS60001168K-page 255 PIC32MX1XX/2XX 28/36/44-PIN FAMILY 29.2 MPLAB XC Compilers The MPLAB XC Compilers are complete ANSI C compilers for all of Microchip's 8, 16, and 32-bit MCU and DSC devices. These compilers provide powerful integration capabilities, superior code optimization and ease of use. MPLAB XC Compilers run on Windows, Linux or MAC OS X. For easy source level debugging, the compilers provide debug information that is optimized to the MPLAB X IDE. The free MPLAB XC Compiler editions support all devices and commands, with no time or memory restrictions, and offer sufficient code optimization for most applications. MPLAB XC Compilers include an assembler, linker and utilities. The assembler generates relocatable object files that can then be archived or linked with other relocatable object files and archives to create an executable file. MPLAB XC Compiler uses the assembler to produce its object file. Notable features of the assembler include: * * * * * * Support for the entire device instruction set Support for fixed-point and floating-point data Command-line interface Rich directive set Flexible macro language MPLAB X IDE compatibility 29.3 MPASM Assembler The MPASM Assembler is a full-featured, universal macro assembler for PIC10/12/16/18 MCUs. The MPASM Assembler generates relocatable object files for the MPLINK Object Linker, Intel(R) standard HEX files, MAP files to detail memory usage and symbol reference, absolute LST files that contain source lines and generated machine code, and COFF files for debugging. The MPASM Assembler features include: 29.4 MPLINK Object Linker/ MPLIB Object Librarian The MPLINK Object Linker combines relocatable objects created by the MPASM Assembler. It can link relocatable objects from precompiled libraries, using directives from a linker script. The MPLIB Object Librarian manages the creation and modification of library files of precompiled code. When a routine from a library is called from a source file, only the modules that contain that routine will be linked in with the application.

PIC32MX1XX/2XX 28/36/44-PIN FAMILY 31.0 50 MHz ELECTRICAL CHARACTERISTICS This section provides an overview of the PIC32MX1XX/2XX 28/36/44-pin Family electrical characteristics for devices operating at 50 MHz. The specifications for 50 MHz are identical to those shown in Section 30.0 "Electrical Characteristics", with the exception of the parameters listed in this chapter. Parameters in this chapter begin with the letter "M", which denotes 50 MHz operation. For example, parameter DC29a in Section 30.0 "Electrical Characteristics", is the up to 40 MHz operation equivalent for MDC29a. Absolute maximum ratings for the PIC32MX1XX/2XX 28/36/44-pin Family 50 MHz devices are listed below. Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at these or any other conditions, above the parameters indicated in the operation listings of this specification, is not implied.
