1. General description
The LPC11U6x are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at
CPU frequencies of up to 50 MHz. The LPC11U6x support up to 256 KB of flash memory,
a 4 KB EEPROM, and 36 KB of SRAM.
The ARM Cortex-M0+ is an easy-to-use, energy-efficient core using a two-stage pipeline
and fast single-cycle I/O access.
The peripheral complement of the LPC11U6x includes a DMA controller, a CRC engine,
one full-speed USB device controller with XTAL-less low-speed mode, two I

interfaces, up to five USARTs, two SSP interfaces, PWM/timer subsystem with six
configurable multi-purpose timers, a Real-Time Clock, one 12-bit ADC, temperature
sensor, function-configurable I/O ports, and up to 80 general-purpose I/O pins.
For additional documentation related to the LPC11U6x parts, see
Section 17
“References”.
