GENERAL DESCRIPTION
(Continued)
together with the Z86C27 and Z86127 to provide support
for mid range and low end TV applications.
Zilog’s DTC offers fast execution, efficient use of memory,
sophisticated interrupts, input/output bit manipulation ca-
pabilities, and easy hardware/software system expansion
along with low cost and low power consumption. The de-
vice provides an ideal performance and reliability solution
for consumer and industrial television applications.
The Z90102/3/4 architecture is characterized by utilizing
Zilog’s advanced Superintegration design methodology.
The device has an 8-bit internal data path controlled by a
Z8 microcontroller and On Screen Display (OSD) logic cir-
cuits and Pulse Width Modulators (PWM). On-chip periph-
erals include two register mapped I/O ports (Ports 2 and
3), interrupt control logic (one software, two external and
three internal interrupts) and a standby mode recovery in-
put port (Port 3, P30).
The OSD control circuits support 6 rows x 20 columns of
characters. The character color is specified by row. One of
the six 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 (5 x 7 dot pattern) or high
resolution (11 x 15 dot pattern) characters.
A 14-bit PWM port provides enough voltage resolution for
a voltage synthesizer tuning system. Three 6-bit PWM
ports are used for controlling audio signal levels. Three 8-
bit PWM ports used to vary picture levels.
For DTC applications demanding powerful I/O capabili-
ties, the Z90102/3/4 fulfills this with 24 I/O pins dedicated
to input and output. These lines are grouped into three
ports, and are configurable under software control to pro-
vide timing, status signals, parallel I/O and an address/da-
ta bus for interfacing to external memory.
There are three basic address spaces available to support
this wide range of configurations: Program Memory, Video
RAM, and Register File. The Register File is composed of
236 bytes of general-purpose registers, two I/O Port regis-
ters, 15 control and status registers and three reserved
registers.
To unburden the program from coping with the real-time
problems such as counting/timing and data communica-
tion, the DTC offers two on-chip counter/timers with a large
number of user selectable modes (Figure 1).
