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

Operating up to 50 MHz, the LPC1115FET48 is an ARM Cortex-M0 microcontroller that features unique onchip API-driven power profiles which provide users with ready-to-use power management templates. The peripheral complement of the LPC1115FET48 includes 64 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 42 general purpose I/O pins.

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. These optimize the CPU performance. PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the system oscillator or the internal RC oscillator.
