GENERAL DESCRIPTION

The Z9020X Family of Digital Television Controllers are

cost-effective members of the Z8^®single-chip

microcontroller family. The devices provides an ideal

performance and reliability solution for consumer and

industrial television applications.

Threebasicaddressspaces, TheProgramMemory, Video

RAM, and Register File, support a wide range of memory

configurations.

For applications demanding powerful I/O capabilities, the

Z9020X's dedicated input and output lines are grouped

into three ports, and are configurable under software

controltoprovidetiming, statussignals, parallelI/Oandan

address/data bus for interfacing to external memory.

TheZ90209istheROMlessIn-CircuitEmulation(ICE)Chip

version of the Z90200 Digital Television Controller Family

used in emulators and development boards.

The device features an 8-bit internal data path controlled

by a Z8 microcontroller, On-Screen Display (OSD) logic

circuits, and Pulse Width Modulators (PWM). On-chip

peripherals include two register mapped I/O ports (Ports 2

and Port 3), interrupt control logic (one software, two

external and three internal interrupts) and a standby mode

recovery input port (Port 3, pin P30).

To unburden the program from coping with the real-time

problemssuchascounting/timinganddatacommunication,

the Z9020X offers two on-chip counter/timers with a large

number of user selectable modes.

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 OSD control circuits support ten rows by 24 columns

ofcharacters.Thecharactercolorisspecifiedbycharacter.

The OSD inter-row spacing is variable and can be

programmed from 0 to 15 horizontal scan lines. The OSD

iscapableofdisplayinghighresolution(14x18dotpattern)

characters.

A 14-bit PWM port provides enough voltage resolution for

a voltage synthesizer tuning system. Ten 8-bit PWM ports

are used for controlling audio signal levels to vary picture

levels.
