LPC5410x

32-bit ARM Cortex-M4/M0+ microcontroller



Up to 50 General-Purpose Input/Output (GPIO) pins. Most GPIOs have

configurable pull-up/pull-down resistors, programmable open-drain mode, and

input inverter.



GPIO registers are located on the AHB for fast access. The DMA supports GPIO

ports.



Up to eight GPIOs (pin interrupts) can be selected as edge-sensitive (rising or

falling edges or both) interrupt requests or level-sensitive (active low or active high)

interrupt requests. In addition, up to eight GPIOs can be selected to contribute a

boolean expression and interrupt generation using the pattern match engine block.



Two GPIO grouped interrupts (GINT) enable an interrupt based on a logical

(AND/OR) combination of input states.



CRC engine.



Timers:



Five 32-bit standard general purpose timers/counters, four of which support up to 4

capture inputs and 4 compare outputs, PWM mode, and external count input.

Specific timer events can be selected to generate DMA requests. The fifth timer

does not have external pin connections and may be used for internal timing

operations.



One State Configurable Timer/PWM (SCT/PWM) with 8 inputs (6 external inputs

and 2 internal inputs) and 8 output functions (including capture and match). Inputs

and outputs can be routed to/from external pins and internally to/from selected

peripherals. Internally, the SCT supports 13 captures/matches, 13 events and 13

states.



32-bit Real-time clock (RTC) with 1 s resolution running in the always-on power

domain. A timer in the RTC can be used for wake-up from all low power modes

including deep power-down, with 1 ms resolution.



Multiple-channel multi-rate 24-bit timer (MRT) for repetitive interrupt generation at

up to four programmable, fixed rates.



Windowed Watchdog Timer (WWDT).



Ultra-low power Micro-tick Timer, running from the Watchdog oscillator, that can be

used to wake up the device from low power modes.



Repetitive Interrupt Timer (RIT) for debug time-stamping and general-purpose use.



Analog peripheral: 12-bit, 12-channel, Analog-to-Digital Converter (ADC) supporting

5.0 Msamples/s. The ADC supports two independent conversion sequences.



Clock generation:



12 MHz internal RC oscillator.



External clock input for clock frequencies of up to 25 MHz.



Internal low-power, watchdog oscillator (WDOSC) with a nominal frequency of 500

kHz.



32 kHz low-power RTC oscillator.



System PLL allows CPU operation up to the maximum CPU rate. May be run from

the internal RC oscillator, the external clock input CLKIN, or the RTC oscillator.



Clock output function for monitoring internal clocks.



Frequency measurement unit for measuring the frequency of any on-chip or

off-chip clock signal.
