NXP LPC1112JHN33/203E

The LPC1111/12/13/14 is a family of low-cost microcontrollers based on the ARM Cortex-M0 core, designed as drop-in replacements for existing 8-bit/16-bit applications. They deliver high performance, low power consumption, an easy-to-use instruction set and memory address space, and more compact code size compared to existing 8-bit/16-bit architectures. The LPC1111/12/13/14 operates at up to 50MHz. Peripherals include: up to 32kB Flash, 8kB data memory, one Fast-mode Plus I²C bus interface, one RS-485/EIA-485 UART, two SPI interfaces with SSP support, four general-purpose timers, one 10-bit ADC, and up to 42 GPIO pins.
