and 4 kB SRAM
Rev. 4.7 — 19 March 2021
Product data sheet
1. General description
The LPC81xM are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at
CPU frequencies of up to 30 MHz. The LPC81xM support up to 16 kB of flash memory
and 4 kB of SRAM.
The peripheral complement of the LPC81xM includes a CRC engine, one I2C-bus
interface, up to three USARTs, up to two SPI interfaces, one multi-rate timer, self wake-up
timer, and state-configurable timer, one comparator, function-configurable I/O ports
through a switch matrix, an input pattern match engine, and up to 18 general-purpose I/O
pins.
