General Description
The Z90365 and Z90361 are members of ZiLOG’s Digital
Signal Processor (DSP)-based TV controller family. They
provide advanced On-Screen Display (OSD), Closed
Caption and TV control features on a single chip. The
Z90365 and Z90361 are the ROM and OTP versions
respectively with 32KWords of ROM and programmable
memory. Both have 640 words of RAM.
The single-cycle, DSP provides high processing power. It
allows the Z90365 and Z90361 to support high character
resolution, expanded color palette selections, expanded
character accommodation, multiple character size choices
and flexible, software-controlled character attributes. The
Z90365 is an ideal choice for mid-to-high end TV products
for both PAL and NTSC standards.
The Z9036x family consists of three basic devices:

Development Tools & Support
Available in One-Time Programmable (OTP) and
MASK ROM Versions, the Z90365 and Z90361 fulfill
Prototype and Production Requirements.
The Z90365 uses ICEbox™ (In-Circuit Emulator) tools
(Z9036900ZEM) to make Programming and
Debugging easy and convenient. ZiLOG Developer
Studio (ZDS) provides easy code generation and
program management.
For code development, ZiLOG offers its specialized
Application Program Interface (API) for OSD. API
Z90369 In-Circuit
Emulation Kit
deals directly with proper sequencing and timing when
interfacing with hardware, shielding the user
application program from tedious and error prone
details.
The Z8933200ZCO, an OSD evaluation board (ZOSD)
is used to synchronize the emulator with a video
display. Refer to the diagram below for a suggested
code development environment.
The Z9036100ZDP is the adapter used to program the
Z90361 OTP. ZiLOG also offers the Z8933200TSC
Protopak to verify code on a television.
