LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller

Other peripherals:

Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down

resistors.

Four general purpose counter/timers with a total of four capture inputs and 13

match outputs.

Programmable WatchDog Timer (WDT).

System tick timer.

Serial Wire Debug and Serial Wire Trace port.

High-current output driver (20 mA) on one pin.

High-current sink drivers (20 mA) on two I2C-bus pins in Fast-mode Plus.

Integrated PMU (Power Management Unit) to minimize power consumption during

Sleep, Deep-sleep, and Deep power-down modes.

Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.

Single power supply (2.0 V to 3.6 V).

10-bit ADC with input multiplexing among 8 pins.

GPIO pins can be used as edge and level sensitive interrupt sources.

Clock output function with divider that can reflect the system oscillator clock, IRC

clock, CPU clock, or the watchdog clock.

Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 40 of

the functional pins.

Brownout detect with four separate thresholds for interrupt and one threshold for

forced reset.

Power-On Reset (POR).

Integrated oscillator with an operating range of 1 MHz to 25 MHz.

12 MHz internal RC oscillator trimmed to 1 % accuracy over the entire temperature

and voltage range that can optionally be used as a system clock.

Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8 MHz.

System PLL allows CPU operation up to the maximum CPU rate without the need for a

high-frequency crystal. May be run from the system oscillator or the internal RC

oscillator.

For USB (LPC1342/43), a second, dedicated PLL is provided.

Code Read Protection (CRP) with different security levels.

Unique device serial number for identification.

Available as 48-pin LQFP package and 33-pin HVQFN package.
