The LPC1200 series extends NXP’s 32-bit ARM microcontroller continuum by targeting a wide range of industrial applications in the areas of factory and home automation. The series offers a wide range of Flash memory sizes, from 32 to 128 KB, with 512 Bytes page erase. Benefitting from the ARM Cortex-M0 Thumb instruction set, the LPC1200 has up to 50% higher code density compared to common 8/16-bit MCUs performing typical tasks. The LPC1200 also features an optimized` ROM-based divide library for Cortex-M0, which offers code size saving and several times the arithmetic performance of software based libraries. The high efficiency of the Cortex-M0 core also helps the LPC1200 achieve lower average power for similar applications. The LPC1200 has up to 55 GPIO and new onboard peripherals including DMA, CRC, comparators, an RTC, and a 1% internal oscillator, which provides the accuracy needed for Baud rate generation.
