NXP Semiconductors LPC86x MCU

LPC86x is a cost-effective 60 MHz Arm Cortex-M0+ based MCU family and supports up to 64KB of flash memory and up to 8 KB SRAM.

LPC86x features small footprint in popular packages and level shifting options thanks to its separate power rails. The peripheral complement includes a CRC engine, I2C-bus interface, I3C-bus interface, up to 3 USARTs, 2 SPI interface, 1 multi-rate timer, self-wake-up timer, 2 FlexTimer with hardware dead-time insertion and quadrature decoding, one 12-bit ADC, one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine and up to 54 general-purpose I/O pins.
