General Description
The Z90356 and Z90351 are the ROM and OTP versions
of a Digital Signal Processor (DSP)-based TV controller
that provide a highly-integrated solution for TV design.
With 64 KWords of ROM and 1KWord of RAM, the
Z90356 provides high processing power.
This DSP architecture supports expanded On-Screen
Display (OSD) features including hardware cursor control,
independent left and right shadows, and semi-transparency.
In addition, the Z90356 has both fixed and programmable
color palettes.
Closed captioning and program blocking provide
additional versatility for the TV manufacturer. Relocatable
CGROM supports unlimited character sets. The Z90356 is
an ideal choice for mid-to-high end TV products for both
PAL and NTSC standards.
The Z9035x family consists of three basic devices:

Development Tools & Support
Available in One-Time Programmable (OTP) and
MASK ROM Versions, the Z90356 and Z90351 fulfill
Prototype and Production Requirements. The Z90356
uses ICEbox™ (In-Circuit Emulator) tools
(Z9036900ZEM) to make Programming and
Debugging easy and convenient.
ZiLOG Developer Studio (ZDS) provides automatic
code generation and program management.
For code development, ZiLOG offers its proven
Application Programmer Interface (API) for OSD. API
deals directly with proper sequencing and timing when
interfacing with hardware, shielding the user
application program from tedious and error prone
details.
The Z9034600ZCO, 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. ZiLOG also offers the
Z9034600TSC Protopak to verify code on a television.
