Z8001

The Z8001 is a general-purpose 16-bit CPU belonging to the Z8001 family of microprocessors.Its architecture is centered around sixteen 16-bit general registers.The CPU deals with 23-bit address spaces and hence can address directly 8MB of memory.The 23-bit address consists of two components:7-bit segment number and 16-bit offset.Facilities are provided to maintain three distinct address spaces-code,data and stack.Is implements a powerful instruction set with flexible addressing modes.These instructions operate on several data types-bit,byte,word(16-bit),long word(32-bit),byte string and word string.The CPU can execute instructions in one of two modes-system and normal.Sometimes these modes are also known as privileged and non-privileged, respectively. The CPU also contains an on-chip memory refresh facility.The Z8001 is software compatible with the Z8002 microprocessor.

The absolute maximum ratings of Z8001 can be summarized as:(1)storage temperature:-65 to +150;(2)voltage at any pin:relative to Vss is -0.3 to +7.0 V;(3)power dissipation:2.5 W.If you want to know more information about Z8001,please download the datasheet in www.seekic.com and www.chinaicmart.com .
