GENERAL DESCRIPTION

The Z86C27 and Z86C97 Digital Television Controller

(DTC)introduceanewlevelofsophisticationtosingle-chip

architecture. The Z86C27/C97 are members of the Z8

single-chip microcontroller family with 8 Kbytes of ROM

(Z86C27), ROMless(Z86C97)and236bytesofRAM. Both

devices are housed in a 64-pin DIP package, and are

CMOS compatible. Having the ROM/ROMless selectivity,

theDTCoffersbothexternalmemoryandpre-programmed

ROM which enables the Z8 microcontroller to be used in a

high volume production application device embedded

with a custom program (customer supplied program). The

Z86C97 ROMless offers the use of external memory rather

than a preprogrammed ROM. This enables the Z8

microcontroller to be used in prototyping, low volume

applications or where code flexibility is required. Zilog’s

DTC offers fast execution, efficient use of memory, sophis-

ticated interrupts, input/output bit manipulation capabili-

ties, 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.

by row. One of the 8 rows is assigned to show two kinds of

colors for bar type displays such as volume control. The

OSD is capable of displaying either low resolution (5x7 dot

pattern) or high resolution (11x15 dot pattern) characters.

The Z86C97 currently supports high resolution char-

acters only.

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.

The DTC applications demand powerful I/O capabilities.

The Z86C27/C97 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.

Therearethreebasicaddressspacesavailabletosupport

this wide range of configurations: Program Memory, Reg-

ister File and Data Memory. The Register File is composed

of 236 bytes of general purpose register, two I/O Port

registers and 15 control and status registers.

The Z86C27/C97 architecture is characterized by utilizing

Zilog’s advanced Superintegration™ design methodol-

ogy. The devices have an 8-bit internal data path con-

trolled by a Z8 microcontroller, and On Screen Display

(OSD) logic circuits/Pulse Width Modulators (PWM). On-

chip peripherals include two register mapped I/O ports

(Ports 2 and Port 3), Interrupt control logic (1 software, 2

external and 3 internal interrupts) and a standby mode

recovery input port (Port 3, pin P30).

problems such as counting/timing and data communica-

tion,theDTC’soffertwoon-chipcounter/timerswithalarge
