Development Tools and Support
Available in OTP and masked ROM versions, the Z90231 and Z90233/Z90234 ful-
fill prototype and production requirements. The Z90231 uses ICEbox
TM
(In-Circuit
Emulator) tools (Z9025900ZEM) to make programming and debugging applica-
tions easy and convenient.
The ZiLOG Developer Studio (ZDS) is a complete software program that provides
easy code generation and program management.
For code development, ZiLOG offers its specialized application program interface
(API) for OSD. The API deals directly with proper sequencing and timing when
interfacing with hardware, shielding the user application programmer from tedious
and error-prone details.
The Z8933200ZCO, an OSD evaluation board, is used to synchronize the emula-
tor with a video display. Refer to Figure 7 for a suggested code development envi-
ronment.

ZiLOG also offers the Z9020900TSC Protopak to verify code on a television.
