The LPC804 are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at CPU frequencies of up to 15MHz. The LPC804 supports 32KB of flash memory and 4 KB of SRAM. The peripheral complement of the LPC804 includes a CRC engine, two I2C-bus interfaces, up to two USARTs, one SPI interface, Capacitive Touch Interface (Cap Touch), one multi-rate timer, self-wake-up timer, one general purpose 32-bit counter/timer, one 12-bit ADC, one 10-bit DAC, one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine, Programmable Logic Unit (PLU), and up to 30 general-purpose I/O pins.
