AMD/VANTIS公司生产的MACH(Macro Array CMOSHigh-density)芯片是一种复杂的可编程阵列逻辑芯片(CPLD-Complex Programmable Logic Device),目前已有1～5个系列产品。其规模从32～512个宏单元,多达2万以上个等效PLD门,传输延时为25～4.5ns,封装为44～352个引脚,具有连续式的内部结构,容易消除竞争险象,是较为理想的可编程器件。它采用了CMOS电可擦除工艺结构,有两种编程方式:使用编程器编程和在系统可编程(ISP-In SystemProgrammability)。后者可通过下载电缆对已装在用户板上的
MACH (Macro Array CMOSHigh-density) chip manufactured by AMD / VANTIS Corporation is a complex programmable logic device (CPLD-Complex Programmable Logic Device), there are 1 to 5 series products. Its size from 32 to 512 macrocells, as many as 20,000 equivalent PLD gate, transmission delay of 25 ~ 4.5ns, package for the 44 ~ 352 pins, with a continuous internal structure, easy to eliminate competition risk , Is the ideal programmable device. It uses a CMOS electrically erasable technology structure, there are two programming methods: using programmer programming and in-system programming (ISP-In SystemProgrammability). The latter can be downloaded by downloading the cables already installed on the user board
