Z8 DIGITAL TELEVISION CONTROLLERS
FEATURES
Z8-Based CMOS Microcontroller for Consum- er Television, Cable Box, and Satellite Re- ceiver Applications 42-Pin SDIP Package except Z90239 (124 PGA) Z8® MCU Core at 6 MHz Mask ROM sizes Available in 16 and 24KB Ten 6-bit Pulse Width Modulators One 14-bit Pulse Width Modulator On-Chip Infrared (IR) Capture Registers Four Channel 4-bit Analog-to-Digital Converter Twenty Seven General Purpose I/O Pins I2C Master Serial Communication Port On Screen Display (OSD) Section Supports Displays up to 10 rows by 24 Columns with
256 Characters
Character Cell Resolution of 14 Pixels by 18 Scan lines Variable Inter-row Spacing from 0–15 Horizontal Scan Lines Foreground and Background Colors Fully Programma- ble by Character GENERAL DESCRIPTION The Z9023X Digital Television Controller (DTC) family is ZiLOG’s latest and most powerful Z8-based DTC product offering. These parts feature larger system RAM and ROM options, together with a host of new features including a new color palette system, flexible inter-row spacing, higher character cell resolution, background mesh effect, dedicated I.R. capture registers, on-chip Analog-to-Digital conver- sion, and a hardware Master mode I2C interface. The famil- iar Z8 core in combination with these advanced features makes the Z9023X family an ideal choice for low to mid- range televisions in both PAL and NTSC markets. The Z9023X family consists of three basic device types; ICE Chip (Z90239), ROM Mask Parts (Z90233/Z90234), and OTP Part (Z90231). The OTP (Z90231) supports field pro- grammable 32KB system ROM. ICE Chip (Z90239) is used in Z90239 Emulator and ProtoPak. As described above, Z90233 supports 16KB system ROM and Z90234 supports 24KB system ROM for mask. The Z9021X family takes full advantage of the Z8’s ex- panded register file space to offer greater flexibility in On Screen Display creation. Note: All signals with an overline, “ ”, are active Low. For ex- ample, B/: (WORD is active Low, only); %/W (BYTE is active Low, only).
