Z86C21开发板套件编程器的可编程适配器插座规格书PDF中文资料

Z86C21属于开发板套件编程器的可编程适配器插座。由Zilog, Inc.制造生产的Z86C21可编程适配器，插座该系列产品旨在简化与微控制器和可编程振荡器等器件的电气连接，这些器件必须在使用前进行电子配置。此类器件通常在产品开发过程中使用，或者用于允许将通用配置工具与各种物理封装的可编程器件一起使用，通常设计成允许无损插拔所要编程的器件。

GENERAL DESCRIPTION

The Z86C21 microcontroller is a member of the Z8 single-chip microcontroller family with 8 Kbytes of ROM and 236 bytes of RAM. The device is packaged in a 40-pin DIP, 44-pin PLCC, or a 44-pin QFP with a ROMless pin option available on the 44-pin versions only. With the ROM/ROMless feature selectively, the Z86C21 offers both external memory and preprogrammed ROM, making it wellsuited for high-volume applications or where code flexibility is required.
