NXP LPC15xx系列MCU马达控制方案
NXP公司的LPC15xx系列是基于72MHz的ARM Cortex-M3内核的MCU,采用三级流水线和哈佛架构,集成了256KB闪存,32KB ROM，4KB EEPROM和多达36KB SRAM，以及多种外设,主要用在嵌入应用如马达控制,太阳能逆变器,家用电器,医疗设备,建筑物和工厂自动化,数字电源.本文介绍了LPC15xx主要特性,框图和LPCXpressoBLDC马达控制板主要特性和电路图.
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.
