[原创]Embest NXP LPC1788 32位ARM Cortex-M3 MCU开发方案

Embest公司的EM-LPC1788开发板是基于NXP公司的LPC1788 32位ARM Cortex-M3 MCU,采用JTAG仿真和调试以及ISP编程,支持各种电源如USB2UART mini USB/USB1/USB2/EXT 5V,主要用在通信如POS终端,网络服务器和多协议桥,工业/医疗如自动化控制,应用控制,机器人控制,HVAC PLC和逆变器等,消费类电子如音频,MP3译码,告警系统,显示器,打印机和小型设备以及汽车电子如汽车告警,GPS监视器等.本文介绍了LPC178x/7x系列主要特性和优势,框图,EM-LPC1788开发板硬件指标和软件指标,框图和电路图.

The LPC178x/7x is an ARM Cortex-M3 based microcontroller for embedded applications requiring a high level of integration and low power dissipation.

The Cortex-M3 is a next generation core that offers better performance than the ARM7 at the same clock rate and other system enhancements such as modernized debug features and a higher level of support block integration. The Cortex-M3 CPU incorporates a 3-stage pipeline and has a Harvard architecture with separate local instruction and data buses, as well as a third bus with slightly lower performance for peripherals. The Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branches.

The LPC178x/7x adds a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. The LPC178x/7x operates at up to 120 MHz CPU frequency.
