Functional description 7.1 Architectural overview The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and the D-code bus. The I-code and D-code core buses allow for concurrent code and data accesses from different slave ports. The LPC185x/3x/2x/1x use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and other bus masters to peripherals. Flexible connections allow different bus masters to access peripherals that are on different slave ports of the matrix simultaneously. 7.2 ARM Cortex-M3 processor The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high performance and low-power consumption. The ARM Cortex-M3 offers many new features, including a Thumb-2 instruction set, low interrupt latency, hardware division, hardware single-cycle multiply, interruptable/continuable multiple load and store instructions, automatic state save and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt controller, and multiple core buses capable of simultaneous accesses. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical Reference Manual. 7.3 System Tick timer (SysTick) The ARM Cortex-M3 includes a system tick timer (SYSTICK) that is intended to generate a dedicated SYSTICK exception at a 10 ms interval.

Individual interrupt flags can also represent more than one interrupt source. 7.6 Event router The event router combines various internal signals, interrupts, and the external interrupt pins (WAKEUP[3:0]) to create an interrupt in the NVIC, if enabled. In addition, the event router creates a wake-up signal to the ARM core and the CCU for waking up from Sleep, Deep-sleep, Power-down, and Deep power-down modes. Individual events can be configured as edge or level sensitive and can be enabled or disabled in the event router. The event router can be battery powered. The following events if enabled in the event router can create a wake-up signal from sleep, deep-sleep, power-down, and deep power-down modes and/or create an interrupt: * External pins WAKEUP0/1/2/3 and RESET * Alarm timer, RTC (32 kHz oscillator running) The following events if enabled in the event router can create a wake-up signal from sleep mode only and/or create an interrupt: * * * * WWDT, BOD interrupts. C_CAN0/1 and QEI interrupts. Ethernet, USB0, USB1 signals. Selected outputs of combined timers (SCTimer/PWM and timer0/1/3). Remark: Any interrupt can wake up the ARM Cortex-M3 from sleep mode if enabled in the NVIC. 7.7 Global Input Multiplexer Array (GIMA) The GIMA routes signals to event-driven peripheral targets like the SCTimer/PWM, timers, event router, or the ADCs. 7.7.1 Features * * * * * Single selection of a source. Signal inversion. Can capture a pulse if the input event source is faster than the target clock. Synchronization of input event and target clock. Single-cycle pulse generation for target. 7.8 On-chip static RAM The LPC185x/3x/2x/1x support up to 136 kB SRAM with separate bus master access for higher throughput and individual power control for low-power operation.

With dual-bank flash memory, the user code can write or erase one flash bank while reading the other flash bank without interruption. A two-port flash accelerator maximizes the flash performance. In-System Programming (ISP) and In-Application Programming (IAP) routines for programming the flash memory are provided in the Boot ROM. 7.10 EEPROM The LPC185x/3x/2x/1x contain up to 16 kB of on-chip byte-erasable and byte-programmable EEPROM memory. The EEPROM memory is divided into 128 pages. The user can access pages 1 through 127. Page 128 is protected. 7.11 Boot ROM The internal ROM memory is used to store the boot code of the LPC185x/3x/2x/1x. After a reset, the ARM processor will start its code execution from this memory. The boot ROM memory includes the following features: * The ROM memory size is 64 kB. * Supports booting from external static memory such as NOR flash, SPI flash, quad SPI flash, USB0, and USB1. * Includes API for OTP programming. * Includes a flexible USB device stack that supports Human Interface Device (HID), Mass Storage Class (MSC), and Device Firmware Upgrade (DFU) drivers. The default boot source is the flash memory. Several other boot modes are available if P2_7 is LOW on reset depending on the values of the OTP bits BOOT_SRC. If the OTP memory is not programmed or the BOOT_SRC bits are all zero, the states of the boot pins P2_9, P2_8, P1_2, and P1_1 determine the boot mode. Table 4.

Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of outputs simultaneously. The value of the output register may be read back as well as the current state of the port pins. All GPIO pins default to inputs with pull-up resistors enabled and input buffer disabled on reset. The input buffer must be turned on in the system control block SFS register before the GPIO input can be read. 7.14.1 Features * Accelerated GPIO functions: - GPIO registers are located on the AHB so that the fastest possible I/O timing can be achieved. - Mask registers allow treating sets of port bits as a group, leaving other bits unchanged. - All GPIO registers are byte and half-word addressable. - Entire port value can be written in one instruction. * Bit-level set and clear registers allow a single instruction set or clear of any number of bits in one port. * Direction control of individual bits. * Up to eight GPIO pins can be selected from all GPIO pins to create an edge- or level-sensitive GPIO interrupt request. * Two GPIO group interrupts can be triggered by any pin or pins in each port. 7.15 AHB peripherals 7.15.1 State Configurable Timer/PWM (SCTimer/PWM) subsystem The SCTimer/PWM allows a wide variety of timing, counting, output modulation, and input capture operations. The inputs and outputs of the SCTimer/PWM are shared with the capture and match inputs/outputs of the 32-bit general-purpose counter/timers. The SCTimer/PWM can be configured as two 16-bit counters or a unified 32-bit counter. In the two-counter case, in addition to the counter value the following operational elements are independent for each half: * State variable. * Limit, halt, stop, and start conditions. * Values of Match/Capture registers, plus reload or capture control values. In the two-counter case, the following operational elements are global to the SCTimer/PWM, but the last three can use match conditions from either counter: LPC185X_3X_2X_1X Product data sheet All information provided in this document is subject to legal disclaimers.

Counters clocked by bus clock or selected input. Up counters or up-down counters. State variable allows sequencing across multiple counter cycles. The following conditions define an event: a counter match condition, an input (or output) condition, a combination of a match and/or and input/output condition in a specified state. * Events control outputs, interrupts, and DMA requests. - Match register 0 can be used as an automatic limit. - In bi-directional mode, events can be enabled based on the count direction. - Match events can be held until another qualifying event occurs. * Selected events can limit, halt, start, or stop a counter. * Supports: - 8 inputs - 16 outputs - 16 match/capture registers - 16 events - 32 states - Match register 0 to 5 support a fractional component for the dither engine 7.15.2 General-Purpose DMA The DMA controller allows peripheral-to memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream provides unidirectional serial DMA transfers for a single source and destination. For example, a bidirectional port requires one stream for transmit and one for receives. The source and destination areas can each be either a memory region or a peripheral for master 1, but only memory for master 0. 7.15.2.1 Features * Eight DMA channels. Each channel can support a unidirectional transfer. * 16 DMA request lines. * Single DMA and burst DMA request signals. Each peripheral connected to the DMA Controller can assert either a burst DMA request or a single DMA request. The DMA burst size is set by programming the DMA Controller. * Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and peripheral-to-peripheral transfers are supported.

All rights reserved. 68 of 155 LPC185x/3x/2x/1x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller * Scatter or gather DMA is supported through the use of linked lists. This means that the source and destination areas do not have to occupy contiguous areas of memory. * Hardware DMA channel priority. * AHB slave DMA programming interface. The DMA Controller is programmed by writing to the DMA control registers over the AHB slave interface. * Two AHB bus masters for transferring data. These interfaces transfer data when a DMA request goes active. Master 1 can access memories and peripherals, master 0 can access memories only. * 32-bit AHB master bus width. * Incrementing or non-incrementing addressing for source and destination. * Programmable DMA burst size. The DMA burst size can be programmed to more efficiently transfer data. * Internal four-word FIFO per channel. * Supports 8, 16, and 32-bit wide transactions. * Big-endian and little-endian support. The DMA Controller defaults to little-endian mode on reset. * An interrupt to the processor can be generated on a DMA completion or when a DMA error has occurred. * Raw interrupt status. The DMA error and DMA count raw interrupt status can be read prior to masking. 7.15.3 SPI Flash Interface (SPIFI) The SPI Flash Interface allows low-cost serial flash memories to be connected to the ARM Cortex-M3 processor with little performance penalty compared to parallel flash devices with higher pin count. After a few commands configure the interface at startup, the entire flash content is accessible as normal memory using byte, halfword, and word accesses by the processor and/or DMA channels. Simple sequences of commands handle erasure and programming. Many serial flash devices use a half-duplex command-driven SPI protocol for device setup and initialization and then move to a half-duplex, command-driven 4-bit protocol for normal operation. Different serial flash vendors and devices accept or require different commands and command formats. SPIFI provides sufficient flexibility to be compatible with common flash devices and includes extensions to help insure compatibility with future devices. 7.15.3.1 Features * * * * Interfaces to serial flash memory in the main memory map. Supports classic and 4-bit bidirectional serial protocols. Half-duplex protocol compatible with various vendors and devices. Quad SPI Flash Interface (SPIFI) with 1-, 2-, or 4-bit data at rates of up to 52 MB per second. * Supports DMA access.

All rights reserved. 75 of 155 LPC185x/3x/2x/1x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller The I2S-bus provides a standard communication interface for digital audio applications. The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. The basic I2S-bus connection has one master, which is always the master, and one slave.

The timer/counter is designed to count cycles of the system derived clock or an externally supplied clock. It can optionally generate interrupts, generate timed DMA requests, or perform other actions at specified timer values, based on four match registers. Each timer/counter also includes two capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.17.1.1 Features * A 32-bit timer/counter with a programmable 32-bit prescaler. * Counter or timer operation. * Two 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event can also generate an interrupt. * Four 32-bit match registers that allow: - Continuous operation with optional interrupt generation on match. - Stop timer on match with optional interrupt generation. - Reset timer on match with optional interrupt generation. * Up to four external outputs corresponding to match registers, with the following capabilities: - Set LOW on match. - Set HIGH on match. - Toggle on match. - Do nothing on match. * Up to two match registers can be used to generate timed DMA requests. 7.17.2 Motor control PWM The motor control PWM is a specialized PWM supporting 3-phase motors and other combinations. Feedback inputs are provided to automatically sense rotor position and use that information to ramp speed up or down. An abort input causes the PWM to release all motor drive outputs immediately . At the same time, the motor control PWM is highly configurable for other generalized timing, counting, capture, and compare applications. 7.17.3 Quadrature Encoder Interface (QEI) A quadrature encoder, also known as a 2-channel incremental encoder, converts angular displacement into two pulse signals. By monitoring both the number of pulses and the relative phase of the two signals, the user code can track the position, direction of rotation, and velocity. In addition, a third channel, or index signal, can be used to reset the position counter. The quadrature encoder interface decodes the digital pulses from a quadrature encoder wheel to integrate position over time and determine direction of rotation. In addition, the QEI can capture the velocity of the encoder wheel. 7.17.3.1 Features * Tracks encoder position.

Any bits of the timer compare function can be masked such that they do not contribute to the match detection. The repetitive interrupt timer can be used to create an interrupt that repeats at predetermined intervals. 7.17.4.1 Features * 32-bit counter. Counter can be free-running or be reset by a generated interrupt. * 32-bit compare value. * 32-bit compare mask. An interrupt is generated when the counter value equals the compare value, after masking. This mechanism allows for combinations not possible with a simple compare. 7.17.5 Windowed WatchDog Timer (WWDT) The purpose of the watchdog is to reset the controller if software fails to periodically service it within a programmable time window. 7.17.5.1 Features * Internally resets chip if not periodically reloaded during the programmable time-out period. * Optional windowed operation requires reload to occur between a minimum and maximum time period, both programmable. * Optional warning interrupt can be generated at a programmable time prior to watchdog time-out. * Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. * Incorrect feed sequence causes reset or interrupt if enabled. * Flag to indicate watchdog reset. * Programmable 24-bit timer with internal prescaler.

RTC power supply is isolated from the rest of the chip. Calibration counter allows adjustment to better than 1 sec/day with 1 sec resolution. Periodic interrupts can be generated from increments of any field of the time registers. Alarm interrupt can be generated for a specific date/time. 7.19.2 Event monitor/recorder The event monitor/recorder allows recording and creating a time stamp of events related to the WAKEUP pins. Sensors report changes to the state of the WAKEUP pins, and the event monitor/recorder stores records of such events. The event recorder can be powered by the backup battery. The event monitor/recorder can monitor the integrity of the device and record any tampering events. 7.19.2.1 Features * Supports three digital event inputs in the VBAT power domain. * An event is defined as a level change at the digital event inputs. * For each event channel, two timestamps mark the first and the last occurrence of an event. Each channel also has a dedicated counter tracking the total number of events. Timestamp values are taken from the RTC. * Runs in VBAT power domain, independent of system power supply. The event/recorder/monitor can therefore operate in Deep power-down mode. * * * * Low power consumption. Interrupt available if system is running. A qualified event can be used as a wake-up trigger. State of event interrupts accessible by software through GPIO. 7.19.3 Alarm timer The alarm timer is a 16-bit timer and counts down at 1 kHz from a preset value generating alarms in intervals of up to 1 min. The counter triggers a status bit when it reaches 0x00 and asserts an interrupt, if enabled. The alarm timer is part of the RTC power domain and can be battery powered. 7.20 System control 7.20.1 Configuration registers (CREG) The following settings are controlled in the configuration register block: * * * * * LPC185X_3X_2X_1X Product data sheet BOD trip settings Oscillator output DMA-to-peripheral muxing Ethernet mode Memory mapping All information provided in this document is subject to legal disclaimers.

All rights reserved. 80 of 155 LPC185x/3x/2x/1x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller * Timer/USART inputs * Enabling the USB controllers In addition, the CREG block contains the part identification and part configuration information. 7.20.2 System Control Unit (SCU) The system control unit determines the function and electrical mode of the digital pins. By default function 0 is selected for all pins with pull-up enabled. For pins that support a digital and analog function, the ADC function select registers in the SCU enable the analog function. A separate set of analog I/Os for the ADCs and the DAC as well as most USB pins are located on separate pads and are not controlled through the SCU. In addition, the clock delay register for the SDRAM EMC_CLK pins and the registers that select the pin interrupts are located in the SCU. 7.20.3 Clock Generation Unit (CGU) The Clock Generator Unit (CGU) generates several base clocks. The base clocks can be unrelated in frequency and phase and can have different clock sources within the CGU. One CGU base clock is routed to the CLKOUT pins. The base clock that generates the CPU clock is referred to as CCLK. Multiple branch clocks are derived from each base clock. The branch clocks offer flexible control for power-management purposes. All branch clocks are outputs of one of two Clock Control Units (CCUs) and can be controlled independently. Branch clocks derived from the same base clock are synchronous in frequency and phase. 7.20.4 Internal RC oscillator (IRC) The IRC is used as the clock source for the WWDT and/or as the clock that drives the PLLs and the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1.5 % accuracy for Tamb = 0 C to 85 C and 3% accuracy for Tamb = -40 C to 0 C and Tamb = 85 C to 105 C. Upon power-up or any chip reset, the LPC185x/3x/2x/1x use the IRC as the clock source. The boot loader then configures the PLL1 to provide a 96 MHz clock for the core and the PLL0USB or PLL0AUDIO as needed if an external boot source is selected. 7.20.5 PLL0USB (for USB0) PLL0 is a dedicated PLL for the USB0 High-speed controller. PLL0 accepts an input clock frequency from an external oscillator in the range of 14 kHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The CCO operates in the range of 4.3 MHz to 550 MHz. 7.20.6 PLL0AUDIO (for audio) The audio PLL PLL0AUDIO is a general-purpose PLL with a small step size. This PLL accepts an input clock frequency derived from an external oscillator or internal IRC. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). A sigma-delta converter modulates the PLL divider ratios to obtain the desired LPC185X_3X_2X_1X Product data sheet All information provided in this document is subject to legal disclaimers.

The output frequency can be set as a multiple of the sampling frequency fs to 32fs, 64fs, 128 fs, 256 fs, 384 fs, 512 fs and the sampling frequency fs can range from 16 kHz to 192 kHz (16, 22.05, 32, 44.1, 48, 96,192) kHz. Many other frequencies are possible as well using the integrated fractional divider. 7.20.7 System PLL1 The PLL1 accepts an input clock frequency from an external oscillator in the range of 1 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz. This range is possible through an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider can be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset. After reset, software can enable the PLL. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s. 7.20.8 Reset Generation Unit (RGU) The RGU allows generation of independent reset signals for individual blocks and peripherals. 7.20.9 Power control The LPC185x/3x/2x/1x feature several independent power domains to control power to the core and the peripherals (see Figure 9). The RTC and its associated peripherals (the alarm timer, the CREG block, the OTP controller, the back-up registers, and the event router) are located in the RTC power-domain. The main regulator or a battery supply can power the RTC. A power selector switch ensures that the RTC block is always powered on.

The LPC185x/3x/2x/1x can wake up from Deep-sleep, Power-down, and Deep power-down modes via the WAKEUP[3:0] pins and interrupts generated by battery powered blocks in the RTC power domain. 7.20.10 Code security (Code Read Protection - CRP) CRP enables different levels of security so that access to the on-chip flash and use of the JTAG and ISP can be restricted. CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by CRP.

All rights reserved. 83 of 155 LPC185x/3x/2x/1x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller There are three levels of the Code Read Protection: * In level CRP1, access to the chip via the JTAG is disabled. Partial flash updates are allowed (excluding flash sector 0) using a limited set of the ISP commands. This level is useful when CRP is required and flash field updates are needed. CRP1 does prevent the user code from erasing all sectors. * In level CRP2, access to the chip via the JTAG is disabled. Only a full flash erase and update using a reduced set of the ISP commands is allowed. * In level CRP3, any access to the chip via the JTAG pins or the ISP is disabled. This mode also disables the ISP override using P2_7 pin. If necessary, the application code must provide a flash update mechanism using the IAP calls or using the reinvoke ISP command to enable flash update via USART0. See Table 5. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. 7.21 Emulation and debugging Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and trace functions are supported in addition to a standard JTAG debug and parallel trace functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four watch points.

Thermal characteristics The average chip junction temperature, Tj (C), can be calculated using the following equation: T j = T amb + P D R th j - a (1) * Tamb = ambient temperature (C), * Rth(j-a) = the package junction-to-ambient thermal resistance (C/W) * PD = sum of internal and I/O power dissipation The internal power dissipation is the product of IDD(REG)(3V3) and VDD(REG)(3V3). The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 8.

Typical battery supply current in Active mode 10.2 Peripheral power consumption The typical power consumption at T = 25 C for each individual peripheral is measured as follows: 1. Enable all branch clocks and measure the current IDD(REG)(3V3). 2. Disable the branch clock to the peripheral to be measured and keep all other branch clocks enabled. 3. Calculate the difference between measurement 1 and 2. The result is the peripheral power consumption. Table 12.

See the I2C-bus specification UM10204 for details. [2] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [3] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [4] Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall times are allowed. [5] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [6] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [7] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time. This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [8] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge.

This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released.

The crystal oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the PLL. The oscillator can operate in one of two modes: slave mode and oscillation mode. * In slave mode, couple the input clock signal with a capacitor of 100 pF (CC in Figure 41), with an amplitude of at least 200 mV (RMS). The XTAL2 pin in this configuration can be left unconnected. * External components and models used in oscillation mode are shown in Figure 42, and in Table 42 and Table 43. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (L, CL and RS represent the fundamental frequency). Capacitance CP in Figure 42 represents the parallel package capacitance and must not be larger than 7 pF. Parameters FC, CL, RS and CP are supplied by the crystal manufacturer. Table 42.

Typical capacitance values for CRTCX1 and CRTCX2 are CRTCX1/2 = 20 (typical) 4 pF. An external clock can be connected to RTCX1 if RTCX2 is left open. The recommended amplitude of the clock signal is Vi(RMS) = 100 mV to 200 mV with a coupling capacitance of 5 pF to 10 pF. LPC18xx RTCX1 RTCX2 XTAL CRTCX1 CRTCX2 002aah066 Fig 43. RTC 32 kHz oscillator circuit 13.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines Connect the crystal on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors CX1, CX2, and CX3 in case of third overtone crystal usage have a common ground plane. Also connect the external components to the ground plain. To keep the noise coupled in via the PCB as small as possible, make loops and parasitics as small as possible. Choose smaller values of CX1 and CX2 if parasitics increase in the PCB layout. Ensure no high-speed or high-drive signals are near the RTCX1/2 signals. 13.5 Standard I/O pin configuration Figure 44 shows the possible pin modes for standard I/O pins with analog input function: * * * * * * Digital output driver enabled/disabled Digital input: Pull-up enabled/disabled Digital input: Pull-down enabled/disabled Digital input: Repeater mode enabled/disabled Digital input: Input buffer enabled/disabled Analog input The default configuration for standard I/O pins is input buffer disabled and pull-up enabled. The weak MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.

All rights reserved. 135 of 155 LPC185x/3x/2x/1x NXP Semiconductors 32-bit ARM Cortex-M3 microcontroller On the LPC185x/3x/2x/1x, USBn_VBUS pins are 5 V tolerant only when VDDIO is applied and at operating voltage level. Therefore, if the USBn_VBUS function is connected to the USB connector and the device is self-powered, the USBn_VBUS pins must be protected for situations when VDDIO = 0 V. If VDDIO is always at operating level while VBUS = 5 V, the USBn_VBUS pin can be connected directly to the VBUS pin on the USB connector. For systems where VDDIO can be 0 V and VBUS is directly applied to the USBn_VBUS pins, precautions must be taken to reduce the voltage to below 3.6 V, which is the maximum allowable voltage on the USBn_VBUS pins in this case. One method is to use a voltage divider to connect the USBn_VBUS pins to VBUS on the USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be greater than 0.7VDDIO to indicate a logic HIGH while below the 3.6 V allowable maximum voltage. For the following operating conditions VBUSmax = 5.25 V VDDIO = 3.6 V, the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V. For bus-powered devices, a regulator powered by USB can provide 3.3 V to VDDIO whenever bus power is present and ensure that power to the USBn_VBUS pins is always present when the 5 V VBUS signal is applied. See Figure 47. Remark: Applying 5 V to the USBn_VBUS pins for a short time while the regulator ramps up might compromise the long-term reliability of the part but does not affect its function.
