NXP Semiconductors LPC185x/3x/2x/1x

32-bit ARM Cortex-M3 microcontroller

7. 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 em ployed so that all p arts of the processing and memory system s

can operate continuously. Typically, while one instruction is being executed, it s successo r

is being decoded, and a thir d 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.

7.4 AHB multilayer matrix

7.5 Nested Vectored Interrupt Controller (NVIC)

The NVIC is part of the Cortex-M3. The tight coupling to the CPU allows for low interrupt

latency and efficient processing of late arriving interrupts.

•Non-Maskable Interrupt (NMI).

•Software interrupt generation .

7.5.2 Interrupt sources

Each peripheral device h as one interrupt line conn ected to the NVIC but can have severa l

interrupt flags. 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 a nd/or create an inter rupt:

•External pins WAKEUP0/1/2/3 and RESET

•Alarm timer, RTC (32 kHz oscillator running)

The following events if enab led in the event router can create a wa ke-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 gener ation 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 throughpu t and individual power control for low-power operation.

7.9 On-chip flash memory

The LPC185x/3x/2x/1x contain up to 1 MB of dual-bank flash program memory. 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) routine s 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 memor y 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 bo oting from external st atic memory such as NOR flash, SPI flash, quad SPI

flash, USB0, and USB1.

•Includes API for OTP progra mming.

•Includes a flexible USB device stack that supports Human Interfa ce Devic e (HI D),

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.

NXP Semiconductors LPC185x/3x/2x/1x

32-bit ARM Cortex-M3 microcontroller

7.13 One-Time Programmable (OTP) memory

The OTP provides 64 bit+ 256 bit of memory for general-purpose use.

7.14 General-Purpose I/O (GPIO)

The LPC185x/3x/2x/1x provides 8 GPIO ports with up to 31 GPIO pins each.

Device pins that are not connected to a specific perip heral function are controlled by the

GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate

registers allow setting or clearing any numbe r of outp uts simultan eou sly. 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 SCT imer/PWM allows a wide variety of timi ng, counting, output modulation, an d input

capture operations. The inputs and outputs of the SCTimer/PWM are shared with the

capture and mat ch inp u ts/outpu ts of the 32-b it ge ne r al- pu rp o se co un te r/ tim er s.

The SCT imer/PWM can be co nfigured 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:

•Clock selection

•Inputs

•Events

•Outputs

•Interrupts

7.15.1.1 Features

•Two 16-bit counters or one 32-bit counter.

•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 cond ition, an input (or

output) condition, a combination of a match and/or and input/output condition in a

specified state.

•Events control outputs, inter rupts, 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 an ot he r qu a lifyin g ev en t 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 perip heral-to memory, memory-to-peripheral,

peripheral- to -p e riphe ra l, an d m em o ry- to -m e mo ry tran sa ct ion s. Eac h DM A stre am

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 requ est 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

periphera l-to -p e rip he ra l tra ns fe rs ar e su pp or te d.

Product data sheet Rev. 5.2 — 8 March 2016 69 of 155

NXP Semiconductors LPC185x/3x/2x/1x

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 area s 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-b it wid e tra n sac tio ns .

•Big-endian and little-endian support. The DMA Controller defaults to little-endian

mode on reset.

•An interrupt to the pr ocessor ca n be gene rated o n a DMA comp letion 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 seria l flash memories to be co nnected to the ARM

Cortex-M3 pr oc es sor with little per form a nc e pe na lty 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 d evices use a half-duplex command-dr iven SPI protocol for device setup

and initialization and then move to a half-duplex, command-driven 4-bit protocol for

normal operation. Different seria l 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 bidir ec tio na l seria l proto co l s.

•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.

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 ca n track the position, direction of rotation,

and velocity. In addition, a third channel, or ind ex signal, can be u sed to rese t th e position

counter. The quadrature encoder interface decodes the digital pulses fro m 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.

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 fun ction and el ectrical mode o f the digit al pin s. By

default function 0 is selected for all pins with pull-up enabled. For pins that support a

digital an d analog function, the ADC function select registers in the SCU enable the

analog function.

A separa te set of analog I/Os for the ADCs and the DAC as well as most USB pins are

located on separate pad s and are not controlled through the SCU.

CPU clock is referred to as CCLK.

Multiple branch cloc ks ar e de riv ed fro m each bas e cloc k. Th e branc h cloc ks offer flexible

control for power-managem ent 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 freque ncy 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 an y chip reset, the LPC185x/ 3x/2x/1x use the IRC as the cl ock source.

The boot loader then configu res 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.

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 whil e 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 outp ut clock. Since the minimum output divider value is 2, it is

insured that the PL L 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 th e PL L, wait fo r th e PLL to lo ck, an d then con nect 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.

NXP Semiconductors LPC185x/3x/2x/1x

32-bit ARM Cortex-M3 microcontroller

The LPC185x/3x/2x/1x support four reduced power modes: Sleep, Deep-sleep ,

Power-down, and Deep power-down.

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 dif ferent levels o f 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.

NXP Semiconductors LPC185x/3x/2x/1x

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. CR P1 do es

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 redu ced 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 us ing 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.

7.21 Emulation and debugging

Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug a nd

trace functions are su pported 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.

CAUTION

If level three Code Read Protection (CRP3) is selected, no future factory testing can be

performed on the device.

8. Limiting values

[1] The following applies to the limiting values:

a) This product includes circuitry designed for the protection of its internal devices from the damaging effects of excessive static

charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.

b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless

otherwise noted.

[2] Including voltage on outputs in 3-state mode.

[3] The peak current is limited to 25 times the corresponding maximum current.

[4] Dependent on package type.

[5] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.

9. Thermal characteristics

The average chip junction temperature, Tj (C), can be calculated using the following

equation:

(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.

10.2 Peripheral power consumption

The typical power con sumption at T = 25 C for each individ ual periphera l is measured as

follows:

1. Enable all branch clock s and measure the curre n t 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 be tween measurement 1 and 2. The re sult is the peripheral

power consum p tio n.

Conditions: VDD(REG)(3V3) = 3.0 V; VBAT = 2.6 V to 3.6 V; CCLK = 12 MHz.

Remark: The recommended operating condition for the battery supply is

VDD(REG)(3V3) > VBAT + 0.2 V.

[2] Simulated using 10 cm of 50 Ω PCB trace with 5 pF receiver input. Rise and fall times measured between

80 % and 20 % of the full output signal level.

[3] The slew rate is configured in the system control block in the SFSP registers using the EHS bit. See the

LPC43xx user manual.

[4] CL = 20 pF. Rise and fall times measured between 90 % and 10 % of the full input signal level.

[5] The drive modes are configured in the system control block in the SFSP registers using the EHD bit. See

the LPC18xx user manual.

11.9 I2C-bus

[1] Parameters are valid over operating temperature range unless otherwise specified. 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.

[9] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 25 0 ns must then be met.

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. Also the acknowledg e timing must meet this set-up time.

11.10 I2S-bus interface

[1] Clock to the I2S-bus interface BASE_APB1_CLK = 150 MHz; peripheral clock to the I2S-bus interface

PCLK = BASE_APB1_CLK / 12. I2S clock cycle time Tcy(clk) = 79.2 ns, corresponds to the SCK signal in the

I2S-bus specification.

12. ADC/DAC electrical characteristics

[1] The ADC is monotonic, there are no missing codes.

[2] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 39.

[3] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after

appropriate adjustment of gain and offset errors. See Figure 39.

[4] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the

ideal curve. See Figure 39.

[5] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset

error, and the straight line which fits the ideal transfer curve. See Figure 39.

[6] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated

ADC and the ideal transfer curve. See Figure 39.

[7] Tamb = 25 C.

[8] Input resistance Ri depends on the sampling frequency fs: Ri = 2 k + 1 / (fs  Cia).

13.2 Crystal oscillator

The crystal oscillator is controlled by the XTAL_OSC_CTRL register in the CGU (see

LPC18xx user manual).

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 repres en t the fun d am ental

frequency). Capacitance CP in Figure 42 repr esent s the pa rallel p ackage cap acit ance

and must not be larger than 7 pF. Parameters FC, CL, RS and CP are supplied by the

crystal manufacturer.

13.3 RTC oscillator

In the RTC oscillator circuit, only the crystal (XTAL) and the capacitances CRTCX1 an d

CRTCX2 need to be connected externally. 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 lef t open. The recommended

amplitude of the clock signal is V i(RMS) = 100 mV to 200 mV with a coupling capacitance of

5 pF to 10 pF.

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 overton e

crystal usag e have a common ground plane . Also connect the exter nal 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 a nalog input function:

•Digital output driver enabled/ dis ab le d

•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.

NXP Semiconductors LPC185x/3x/2x/1x

32-bit ARM Cortex-M3 microcontroller

On the LPC185x/3x/2x/1x, USBn_VBUS pins ar e 5 V tolerant only wh en 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 direc tly to the VBUS pin on the USB con n ect or.

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 operat ing conditions

VBUSmax = 5.25 V

VDDIO = 3.6 V,

the voltage divider shou ld pr ov ide a red uc tio n of 3.6 V/5 .2 5 V or ~0. 68 6 V.

For bus-powered devices, a regulator powered by USB can provide 3.3 V to VDDIO

whenever bus power is presen t and ensu re th at 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.

Remark: If the VBUS function of the USB1 interface is not connected, configure the pin

function for GPIO using the function control bits in the SYSCON block.

Remark: In OTG mode, it is important to be able to detect the VBUS level and to charge

and discharge VBUS. This requires adding active devices that disconnect the link when

VDDIO is not present.
