GENERAL DESCRIPTION
The Z901XX 40-pin Digital Television Controller is a cost-
effective member of the Z8® single-chip microcontroller
family. The device provides an ideal performance and
reliability solution for consumer and industrial television
applications.
The Z901XX offers mask-programmed ROM, which en-
ables the Z8 microcontroller to be used in a high-volume
production application device embedded with a custom
program (customer-supplied program) and combines to
provide support for mid-range and low-end TV applica-
tions.
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).
The OSD control circuits support six rows by 20 columns
of characters. The character color is specified 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 either low resolution (5x7 dot pattern)
or high resolution (11x15 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, and
Three 8-bit PWM ports used to vary picture levels.
Three basic address spaces, The Program Memory, Video
RAM, and Register File, support a wide range of memory
configurations.
For applications demanding powerful I/O capabilities, the
Z901XX's dedicated input and output lines are grouped
into three 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.
To unburden the program from coping with the real-time
problems such as counting/timing and data communication,
the Z901XX 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).
