LPC802

32-bit ARM Cortex-M0+ microcontroller



On-chip ROM APIs for integer divide.



Free Running Oscillator (FRO) API.



Digital peripherals:



High-speed GPIO interface connected to the ARM Cortex-M0+ I/O bus with up to

17 General-Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors,

programmable open-drain mode, and input inverter. GPIO direction control

supports independent set/clear/toggle of individual bits.



High-current source output driver (20 mA) on three pins.



Switch matrix for flexible configuration of each I/O pin function.



CRC engine.



Timers:



One 32-bit general purpose counter/timer, with four match outputs and three

capture inputs. Supports PWM mode, and external count



Two channel Multi-Rate Timer (MRT) for repetitive interrupt generation at up to four

programmable, fixed rates.



Self-Wake-up Timer (WKT) clocked from either Free Running Oscillator (FRO), a

low-power, low-frequency internal oscillator, or an external clock input.



Windowed Watchdog timer (WWDT).



Analog peripherals:



One 12-bit ADC with up to 12 input channels with multiple internal and external

trigger inputs and with sample rates of up to 480 Ksamples/s. The ADC supports

two independent conversion sequences.



Comparator with four input pins and external or internal reference voltage.



Serial peripherals:



Two USART interfaces with pin functions assigned through the switch matrix and

one fractional baud rate generators.



One SPI controllers with pin functions assigned through the switch matrix.



One I2C-bus interface. Supports Standard mode and Fast mode.



Clock generation:



Free Running Oscillator (FRO). This oscillator provides a selectable

9 MHz, 12 MHz and 15 MHz outputs that can be used as a system clock. The FRO

is trimmed to ±1 % accuracy over the entire voltage and temperature range of 0 C

to 70 C.



1 MHz low power oscillator can be used as a clock source.



Clock output function with divider that can reflect all internal clock sources.



Power control:



Reduced power modes: sleep mode, deep-sleep mode, power-down mode, and

deep power-down mode.



Wake-up from deep-sleep and power-down modes on activity on USART, SPI, and

I2C peripherals.



Wake-up from deep power-down mode on multiple pins.



Timer-controlled self wake-up from sleep, deep-sleep, and power-down modes.



Power-On Reset (POR).



Brownout detect (BOD).
