LPC1342FHN33中文资料基于ARM® Cortex®-M3内核的入门级32位微控制器(MCU)数据手册恩XP规格书

描述 Description

The LPC1342FHN33 is an Arm Cortex-M3 based microcontroller for embedded applications featuring a high level of integration and low power consumption. The Arm Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The Arm Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The Arm Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching.
