Z8018008VSG屬于集成電路（IC）的微處理器。由Zilog, Inc.制造生產(chǎn)的Z8018008VSG微處理器微處理器產(chǎn)品是用于信息和數(shù)據(jù)處理的集成電路。與主要按照制造商所選術(shù)語而視為微控制器的類似產(chǎn)品相比，這些器件有所不同。但是按照傳統(tǒng)，微處理器不會在設(shè)備內(nèi)集成工作存儲器，不太可能集成混合信號外設(shè)，并且可能在更為復(fù)雜的軟件范式下使用，這些范式涉及使用操作系統(tǒng)來管理多任務(wù)同時執(zhí)行。

General Description

The Z80180? is an 8-bit MPU which provides the benefits of reduced system costs and also provides full backward compatibility with existing ZiLOG Z80 devices. Reduced system costs are obtained by incorporating several key system functions on-chip with the CPU. These key functions include I/O devices such as DMA, UART, and timer channels. Also included on-chip are wait-state generators, a clock oscillator, and an interrupt controller.

The Z80180? is housed in 80-pin QFP, 68-pin PLCC, and 64-pin DIP packages.
