    Intro to Low-Power Cortex-M0 LPC1100 MCU (NXP eLearning)


The LPC1114FA44 is an ARM Cortex-M0 microcontroller and it can operate up to 50 MHz. The peripheral complement of the LPC1114FA44 includes 32 kB of flash memory, 8 kB of data memory, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 UART, two SPI interfaces with SSP features, four general purpose counter/timers, a 10-bit ADC, and 38 general purpose I/O pins. In addition, the LPC1114FA44 features unique on-chip API-driven power profiles which provide users with ready-to-use power management templates. Optimized for CPU performance, CPU efficiency and lowest active current, the power profiles enable maximum operating frequency through the entire voltage range from 1.8 V to 3.6 V without compromising speed or functionality.
