[原创] Microchip dsPIC33FJ128GP脉搏血氧仪设计方案

Microchip公司的dsPIC33FJ128GP是集成了高达128KB闪存和16KB SRAM以及先进模拟特性的16位数字信号处理器(DSC),内核性能高达40MIPS,主要用在高效率马达驱动,铂级数字电源和低功耗长寿命手持设备.本文介绍了dsPIC33FJ128GP主要特性,框图,已及采用dsPIC DSC的脉搏血氧仪设计方案主要亮点,系统框图和电路图.

Microchip’s 16-bitdsPIC® Digital Signal Controllers provide designers with an easy upgrade path from 8-bitPIC® microcontrollers and a cost effective option to 32-bit MCUs. The broad product line includes everything from eXtreme Low Power microcontrollers to high performance digital signal controllers. With single cycle execution, deterministic interrupt response, zero overhead looping, and fast DMA, the dsPIC family also adds a single cycle 16x16 MAC and 40-bit accumulators, ideal for math intensive applications like motor control and digital power.
