NXP Keil LPC1768 ARM Cortex－M3 MCU开发方案

NXP公司的LPC1769/68/67/66/65/64/63是基于ARM Cortex－M3核的微控制器,具有高度集成和低功耗,工作频率高达100MHz/120MHz,采用三级流水线和哈佛架构,具有独立的本地指令,数据总线和用于外设的第三总线,高达512KB闪存,主要用在电表,告警系统,照明系统,白色家电,工业网络和马达控制.本文介绍了LPC1769/68/67/66/65/64/63主要特性和优势,框图,以及Keil LPC1768评估板MCB1700主要特性和电路图.

The LPC1769/68/67/66/65/64/63 are ARM Cortex-M3 based microcontrollers 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 LPC1768/67/66/65/64/63 operate at CPU frequencies of up to 100 MHz. The LPC1769 operates at CPU frequencies of up to 120 MHz. 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.
