LPC11U6x 32-bit ARM Cortex-M0+ microcontroller up to 256 KB flash and 36 KB SRAM 4 KB EEPROM USB 12-bit ADC Rev. 1.5 12 August 2020 Product data sheet 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, 2 one full-speed USB device controller with XTAL-less low-speed mode, two I C-bus 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. 2.
