采用dsPIC33F和PIC24H的Microstick開發(fā)方案設(shè)計

本文 首先介紹了PIC24H系列16 位高性能單片機主要特性，方框圖，接著介紹了Microstick 開發(fā)板主要特性及其電路圖。
Microstick 開發(fā)板是Microchip 公司的用來開發(fā)16位數(shù)字信號控制器（DSC）dsPIC33F 和16位MCU PIC24H，主要用來開發(fā)智能傳感器和其它嵌入式控制應(yīng)用。Microstick 開發(fā)板的成本很低，它集成了編程器/調(diào)試器，可以單獨使用，也可以插入原型板進行開發(fā)，成本很低。

PIC24H系列16 位高性能單片機主要特性：

通信模塊：

• 4 線SPI （最多2 個模塊）：

- 幀支持與簡單編解碼器的I/O 接口

- 支持8 位和16 位數(shù)據(jù)

- 支持所有串行時鐘格式和采樣模式

比較器模塊：

• 帶可編程輸入/ 輸出配置的兩個模擬比較器

CMOS 閃存技術(shù)：

• 低功耗高速閃存技術(shù)

• 全靜態(tài)設(shè)計

• 3.3V （±10%）工作電壓

• 工業(yè)級和擴展級溫度

• 低功耗

封裝：

• 28 引腳SPDIP/SOIC/QFN-S

• 44 引腳TQFP/QFN
