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.
