Scalable Entry Level 32-bit Microcontroller (MCU) based on Arm® Cortex®-M0+ and Cortex®-M0 Cores

Overview

The LPC11Uxx MCU Family is an Arm^® Cortex^®-M0+ and Cortex-M0 based- low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11Uxx MCU family is designed for 8/16-bit microcontroller operations, offering performance, low power, simple instruction set reduce code size compared to existing 8/16-bit architectures.

Equipped with a highly flexible and configurable full-speed USB 2.0 device controller, the LPC11Uxx family brings design flexibility and seamless integration to today’s demanding connectivity solutions. The peripheral complement of the LPC11Uxx family includes up to 256KB of flash memory, up to 32 KB of SRAM, up to two I2C-bus interfaces, up to five USARTs, up to two SSP, PWM/timer subsystem with up to six configurable multi-purpose timers, an Analog to Digital Converter, and up to 80 general purpose I/O pins.
