The LPC822M101JDH20J is a 32-bit ARM Cortex-M0+ Microcontroller operating at CPU frequencies of up to 30MHz. The LPC82x support up to 32kB of flash memory and 8kB of SRAM. The peripheral complement of the LPC82x includes a CRC engine, four I2C-bus interfaces, up to three USARTs, up to two SPI interfaces, one multi-rate timer, self-wake-up timer and state-configurable timer with PWM function (SCTimer/PWM), a DMA, one 12-bit ADC and one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine and up to 29 general-purpose I/O pins. State configurable timer (SCTimer/PWM) with input and output functions (including capture and match) for timing and PWM applications. Each SCTimer/PWM input is multiplexed to allow selecting from several input sources such as pins, ADC interrupt or comparator output.
