Description

The Z90102/3/4 40-pin Low-Cost Digital Television Controller are members of the Z8®STOP Mode MCU singlechip family with 4 6, and 8 KB of ROM and 236 bytes of RAM. The device is offered in a 40-pin package and is CMOS compatible. The DTC offers mask programmed ROM which enables the Z8® MCU to be used in a high volume production application device embedded with a custom  program (customer supplied program) and combines 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 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 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 circuits and Pulse Width Modulators (PWM). On-chip peripherals 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 input 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 capabilities, 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 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, Video RAM, and Register File. The Register File is composed of 236 bytes of general-purpose registers, two I/O Port registers, 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 communication, the DTC offers two on-chip counter/timers with a large number of user selectable modes (Figure 1).
