摘　　要：介绍了ATmega128单片机与CPLD在数字继电保护保护装置中的硬件设计与应用。单片机与CPLD配合应用,改善了原来传统的由单片机、程序存储器、数据存储器、数据驱动芯片、锁存器、地址译码器等一些外围芯片组成的硬件结构,形成了结构简单而功能全面的CPU+CPLD结构。大大简化了硬件从而提高了系统的可靠性和抗干扰能力,缩短了开发周期和降低了产品成本。且制造出商用产品,产生了良好的社会和经济效益。This paper introduces the ATmega128 MCU and CPLD Relay protection device in the digital hardware design and application. MCU and CPLD applications with improved from the original traditional microcontroller, program memory, data memory, data-driven chip latch, address decoder chip peripherals such as the composition of the hardware structure, forming a structure of easy The full-featured structure of CPU ＋ CPLD. Greatly simplifies the hardware in order to improve the reliability of the system and anti-jamming capabilities, shortening the development cycle and reduces the cost of the product. And to create commercial products, have had a good social and economic benefits.
