An application-specific controller designed to provide complete audio and video
control of television receivers and video recorders, the Z90255 provides
advanced OSD features. Figure 1 illustrates a typical TV system application using
the Z90255. Figure 2 is a block diagram of the Z90255 architecture.
Z90255 ROM and Z90251 OTP 32 KB
TV Controller with On-Screen Display
The Z90251 is the one-time programmable (OTP) controller used to develop
code or prototypes for specific television applications or initial limited
production. Program ROM and Character Generation ROM (CGROM) in
the Z90251 are both programmable.
The Z90255 incorporates the ROM code developed by the customer with
the Z90251. Customer code is masked into both program ROM and
CGROM.
