LPC812M101JD20J

The LPC81xM is a family of low-cost, 32-bit MCUs based on the ARM Cortex-M0+, operating at CPU frequencies up to 30 MHz. The LPC81xM supports up to 16 kB of flash memory and 4 kB of SRAM. Peripherals include: a CRC engine, an I2C bus interface, up to three USARTs, up to two SPI interfaces, a multi-rate timer, a self-wake-up timer, a state-configurable timer, a comparator, function-configurable I/O ports with a switch matrix, an input pattern match engine, and up to 18 general-purpose I/O pins.
