[原创] NXP LPC1549马达控制方案

NXP公司的LPC15xx系列是基于ARM Cortex-M3核的微控制器(MCU),具有丰富外设和非常低的功耗,CPU频率高达72MHz,采用3级流水线和哈佛架构,多达256KB片上编程的闪存,36KB SRAM和4KB EEPROM,主要用在马达控制,太阳能逆变器,马达驱动器,家用电器,建筑物和工厂自动化,工业和蔼医疗以及数字电源.本文介绍了LPC15xx系列主要特性和优势,框图,以及LPC1549马达控制板主要特性,框图和电路图.

The LPC15xx are ARM Cortex-M3 based microcontrollers for embedded applications featuring a rich peripheral set with very 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 LPC15xx operate at CPU frequencies of up to 72 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.
