Z86C96

CPS DC-4049-02

GENERAL DESCRIPTION

The Z86C96 microcontroller introduces a new level of
sophistication to single-chip architecture. The Z86C96 is a
member of the Z8 single-chip microcontroller family with
256 bytes of general-purpose RAM.

The MCU is housed in 64-pin DIP and 68-pin Leaded Chip­Carrier packages and is manufactured in CMOS technol­ogy.

Zilog’s CMOS microcontroller 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.

The Z86C96 architecture is characterized by Zilog’s 8-bit
microcontroller core. The device offers a flexible I/O
scheme, an efficient register and address space structure,
multiplexed capabilities between address/data, I/O, and a
number of ancillary features that are useful in many indus­trial and advanced consumer applications.

The device applications demand powerful I/O capabilities.
The Z86C96 fulfills this with 52 pins dedicated to input and
output. These lines are grouped into six 8-bit ports and one

DC-4049-02 (6-8-93)

4-bit port. The ports are configurable under software
control to provide timing, status signals, serial or parallel
I/O with or without handshake, and an address/data bus
for interfacing external memory.

There are three basic address spaces available to support
this wide range of configuration: program memory, data
memory and 236 general-purpose registers.

To unburden the program from coping with the real-time
problems such as counting/timing and serial data commu­nication, the Z86C96 offers two on-chip Counter/Timers
with a large number of user selectable modes, and a
Asynchronous Receiver/Transmitter (UART - see block
diagram).

Notes:

All Signals with a preceding front slash, "/", are active Low, e.g.:
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
