General Description
ZiLOG’s eZVision Z90T36x TV controller with
On-Screen Display (OSD) is a highly integrated solution
for television design. The Z90T36x features a high-speed
16-bit, advanced Digital Signal Processor (DSP) and
powerful OSD engine. Flexible and sophisticated, the
OSD includes video display attributes, semi-transparency,
programmable color palettes, and a hardware cursor for
easy user interface. The Z90T36x supports parental
control, closed captioning, and Extended Data System
(XDS).
The Z90T36x is an ideal choice for mainstream television
sets for both PAL and NTSC standards.
The Z90T36x family consists of three basic devices
› the Z90T365 masked ROM (32 KWords)
› the Z90T366 masked ROM (64 KWords)
› the Z90T361 One Time Programmable (OTP) device
In addition, ZiLOG provides a comprehensive
development suite for television system developers
including an emulator capable of OTP programming,
OSD evaluation board, C-compiler, Application
Programming Interface (API), ZiLOG’s Developer Studio
(ZDS) software, and Graphical User Interface (GUI) OSD
design tools. These tools enable TV developers to work
efficiently and effectively to bring new products to
market.
