基于MSP430F169的最小系统设计

The Mini-system Design Based on MSP430F169

单片机最小系统,或称为最小应用系统,是指用最少的元件组成的单片机可以工作的系统。对于MSP430系列单片机来说,最小系统一般应该包括:单片机、晶振电路、复位电路。本文介绍了MSP430F169单片机的特点,设计了MSP430最小系统中电源模块、复位电路模块、晶振电路模块、JTAG接口模块、串口通讯模块的电路原理图,并介绍了各部分的功能。该最小系统可以进行在线下载、仿真和调试,经实验证明原理正确可靠,可以广泛应用于教学、科研和电子设计领域。

The mini-system,mini-application system,is made up of the minimum components.In regard to MSP430 series microcontrollers,the mini-system generally includes MSP430F169,oscillator circuit and reset circuit.In the paper,the characteristics of MSP430F169 are introduced.Also the schematic diagrams of circuit theory about those modules such as power module,reset circuit module,oscillator circuit module,TAG module,and series module are designed and presented.In addition,the functions of all modules are put forward.The minisystem can be used for on-line download,emulation and debug,and as proved by lots of experiments,it is scientific,dependable,and can be broadly adapted to the fields of the education,scientific research and electric design.
