The LPC1227FBD48/301 is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 30MHz. Benefitting from the ARM Cortex-M0 thumb instruction set have up to 50% higher code density compared to common 16-bit microcontroller performing typical tasks. The LPC122x also feature an optimized ROM-based divide library for Cortex-M0, which offers several times the arithmetic performance of software-based libraries, as well as highly deterministic cycle time combined with reduced flash code size. The device incorporates 128kB internal flash, 8kB internal RAM, 8-channel 10-bit A/D converter with sample rates of up to 400ksps, four general purpose counters/timers and 39 general-purpose I/O pins. This device also features peripherals like two USARTs, one inter-integrated circuit (I2C) and one serial peripheral interface (SPI) module.
