LPC1112FD20/102,52 Datasheet PDF - NXP

●Overview

●The LPC1112FD20 is an ARM Cortex-M0 based, low-cost 32-bit MCU, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The LPC1112FD20 operates at CPU frequencies of up to 50 MHz. The LPC1112FD20 includes up to 16 kB of flash memory, up to 4 kB of data memory, one Fastmode Plus I²C-bus interface, one RS-485/EIA-485 UART, one SPI interface with SSP features, four general purpose counter/timers, a 10-bit ADC, and up to 16 general purpose I/O pins.
