LPC1227FBD48/301,1

ARM微控制器 - MCU CORTEX M0 128K FL 8K DMA CRC ADC COMPARTR

32-bit ARM Cortex-M0 microcontroller; up to 128 kB flash and  8 kB SRAM

General description

The LPC1227FBD48/301,1 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.
