Z86C90集成电路（IC）的微控制器规格书PDF中文资料

Z86C90属于集成电路（IC）的微控制器。由Zilog, Inc.制造生产的Z86C90微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。

GENERAL DESCRIPTION

The Z86C90/C89 CCP™ (Consumer Controller Processor) introduces a new level of sophistication to single-chip architecture. The Z86C90/C89 are ROMless members of the Z8 single-chip microcontroller family with 236 bytes of general purpose RAM.

The only difference that exists between the Z86C89 and the Z86C90 is that the on-chip oscillator of the Z86C89 can accept an external RC network or other external clock source, while the Z86C90s on-chip oscillator accepts a crystal, ceramic resonator, LC, or external clock source drive. The CCP controllers are housed in a 40-pin DIP, 44-pin Leaded Chip Carrier, or a 44-pin Quad Flat Pack, and are CMOS compatible. The CCP offers the use of external memory which enables this Z8 microcomputer to be used where code flexibility is required. Zilogs CMOS microcomputer offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
