GENERAL DESCRIPTION

The Z86E47 Digital Television Controller (DTC) introduce

a new level of sophistication to single-chip architecture.

The Z86E47 is a member of the Z8 single-chip

microcontroller family with 16 Kbytes of OTP (One-Time-

Programmable) ROM and 236 bytes of RAM. The device

is housed in a 64-pin DIP package, and is CMOS compat-

ible. The part features ROMs for program storage and

character generation. The Z86E47 microcontroller may be

used in prototyping, low volume applications or where

code development is required. Zilog’s DTC offers fast

execution, efficient use of memory, sophisticated inter-

rupts, input/output bit manipulation capabilities, and easy

hardware/software system expansion along with low cost

and low power consumption. The device provides an ideal

performance and reliability solution for consumer and

industrial television applications.

The Z86E47 architecture utilizes Zilog’s advanced

Superintegration™ design methodology. The device has

an 8-bit internal data path controlled by a Z8 microcontroller,

On-Screen Display (OSD) logic circuits/Pulse Width Modu-

lators (PWM). On-chip peripherals include five register/

memory mapped I/O ports (Ports 2, 3, 4, 5, and 6), Interrupt

control logic (1 software, 2 external and 3 internal inter-

rupts) and a standby mode recovery input port (Port 3, pin

P30).

The OSD control circuits support eight rows by 20 columns

for 128 kinds of characters. The character color is speci-

fied by row. One of the eight rows is assigned to show two

kinds of colors for bar type displays such as volume

control. The OSD is capable of displaying high resolution

(11x15 dot pattern) characters.

A 14-bit PWM port provides enough voltage resolution for

a voltage synthesizer tuning system. Seven 6-bit PWM

ports are used for controlling audio signal level. Five 8-bit

PWM ports are used to vary picture levels.

DTC applications demand powerful I/O capabilities. The

Z86E47 fulfills this with 35 I/O pins dedicated to input and

output. These lines are grouped into five ports, and are

configurable under software control to provide timing,

status signals, parallel I/O and an address/data bus for

interfacing to external memory.

There are three basic address spaces available to support

this wide range of configurations: Program Memory, Reg-

ister File and Data Memory. The Data Memory address

space contains a number of control registers for the

PWMs, OSD, and I/O Ports 4, 5, and 6. Specifically, there

are 13 PWM and eight OSD control registers mapped into

the external memory address space. Three I/O registers

for Ports 4, 5, and 6 reside in data memory space as well.

The Register File is composed of 236 bytes of general

purpose register, two I/O Port registers and 15 control and

status registers.

To unburden the program from coping with the real-time

problems such as counting/timing and data communica-

tion, the DTC’s offer two on-chip counter/timers with a large

number of user selectable modes (see block diagram).

Note: 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).
