NXP LPC15xx系列MCU马达控制方案

来源:    编辑:    发布时间:2016-09-08 06:28:51    浏览量:

NXP企业的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.本文先容了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.

The LPC15xx includes up to 256 kB of flash memory, 32 kB of ROM, a 4 kB EEPROM,and up to 36 kB of SRAM. The peripheral complement includes one full-speed USB 2.0 device, two SPI interfaces, three USARTs, one Fast-mode Plus I2C-bus interface, one C_CAN module, PWM/timer subsystem with four configurable, multi-purpose State Configurable Timers (SCTimer/PWM) with input pre-processing unit, a Real-time clock module with independent power supply and a dedicated oscillator, two 12-channel/12-bit,2 Msamples/s ADCs, one 12-bit, 500 kSamples/s DAC, four voltage comparators with internal voltage reference, and a temperature sensor. A DMA engine can service most peripherals.

LPC15xx主要特性:
? System:
? ARM Cortex-M3 processor (version r2p1), running at frequencies of up to 72 MHz.
? ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
? System tick timer.

焊盘的大小圆形焊盘的大小尺寸主要取决于引线孔的直径和焊盘的外径(其它焊盘种类可参考其确定)。
(1)引线孔的直径
引线孔钻在焊盘中心,孔径应该比焊接的元器件引线的直径略大一些,这样才
