Z86E21
CMOS Z8® OTP
MICROCONTROLLER
GENERAL DESCRIPTION
The Z86E21 microcontroller (MCU) introduces the next
level of sophistication to single-chip architecture. The
Z86E21 is a member of the Z8 single-chip microcontroller
family with 8 Kbytes of EPROM and 236 bytes of general
purpose RAM.
ThedeviceapplicationsdemandpowerfulI/Ocapabilities.
The Z86E21 fulfills this with 32-pin dedicated to input and
output. These lines are grouped into four ports. Each port
consists of eight lines, and is 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.
TheZ86E21isapincompatible,One-Time-Programmable
(OTP) version of the Z86C21. The Z86E21 contains 8
Kbytes of EPROM memory in place of the 8 Kbyte of ROM
on the Z86C21.
Therearethreebasicaddressspacesavailabletosupport
this wide range of configuration: Program Memory, Data
Memory and 236 General-Purpose registers.
The MCU is housed in a 40-pin DIP, 44-pin Leaded Chip-
Carrier, or a 44-pin Quad Flat Pack, and is manufactured
in CMOS technology. The ROMless pin option is available
on the 44-pin versions only. The MCU can address both
external memory and preprogrammed ROM which en-
ables this Z8 microcomputer to be used in high volume
applications or where code flexibility is required.
To unburden the program from coping with real-time
problemssuchascounting/timingandserialdatacommu-
nication,theZ86E21offerstwoon-chipcounter/timerswith
a large number of user selectable modes, and an asyn-
chronousreceiver/transmitter(UART)(seeFunctionalBlock
Description).
Zilog’s CMOS microcontroller offers fast execution, effi-
cientuseofmemory,sophisticatedinterrupts,input/output
bit manipulation capabilities, and easy hardware/software
system expansion along with low cost and low power
consumption.
In ROM Protect Mode, the instructions LDC, LDCI, LDE
and LDEI are disabled when reading address locations
%0000 to %1FFF.
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).
The Z86E21 architecture is based on Zilog’s 8-bit
microcontroller core. The device offers a flexible I/O
scheme,anefficientregisterandaddressspacestructure,
multiplexed capabilities between address/data, I/O, and a
number of ancillary features that are useful in many indus-
trial and advanced scientific applications.

ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the de-
vice. This is a stress rating only; operation of the device at
any condition above those indicated in the operational
sections of these specifications is not implied. Exposure to
absolute maximum rating conditions for an extended pe-
riod may affect device reliability.
