LPC1227

LPC122x 32-bit ARM Cortex-M0 microcontroller; up to 128 kB flash and 8 kB SRAM Rev. 2 — 26 August 2011 Product data sheet 1. General description The LPC122x extend NXP's 32-bit ARM microcontroller continuum and target a wide range of industrial applications in the areas of factory and home automation. Benefitting from the ARM Cortex-M0 Thumb instruction set, the LPC122x have up to 50 % higher code density compared to common 8/16-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 ARM Cortex-M0 efficiency also helps the LPC122x achieve lower average power for similar applications. The LPC122x operate at CPU frequencies of up to 45 MHz.They offer a wide range of flash memory options, from 32 kB to 128 kB. The small 512-byte page erase of the flash memory brings multiple design benefits, such as finer EEPROM emulation, boot-load support from any serial interface and ease of in-field programming with reduced on-chip RAM buffer requirements. The peripheral complement of the LPC122x includes a 10-bit ADC, two comparators with output feedback loop, two UARTs, one SSP/SPI interface, one I2C-bus interface with Fast-mode Plus features, a Windowed Watchdog Timer, a DMA controller, a CRC engine, four general purpose timers, a 32-bit RTC, a 1 % int...
