一、概述Mos tek 公司在M68000的基础上开发了一种16位高性能单片微型计算机,称为 MK68200,它有两个产品 MK68200和 MK68E200,两者区别在于前者有片内 ROM,后者片内无ROM,使用时需外接 EPROM;前者采用48脚双列直插式封装,后者采用方形直插式封装·其引脚功能如图1所示。由于 MK68200具有扩展总线功能,使用方式不同,其引脚功能也有所不同。 I. Overview Mostek developed a 16-bit high-performance monolithic microcomputer based on the M68000 called the MK68200, which has two products, the MK68200 and the MK68E200, with the difference that the former has an on-chip ROM and the latter No ROM inside, the need to use an external EPROM; the former 48-pin dual in-line package, the latter with a square in-line package · pin function shown in Figure 1. As the MK68200 has extended bus functions, use different ways, the pin functions are also different.
