GENERAL DESCRIPTION
The Z90102/3/4 40-pin Low-Cost Digital Television Con-
troller are members of the Z8
chip family with 4, 6, and 8 KB of ROM and 236 bytes of
RAM. The device is offered in a 40-pin package and is
STOP Mode MCU single-
CMOS compatible. The DTC offers mask programmed
ROM which enables the Z8
MCU to be used in a high vol-
ume production application device embedded with a cus-
tom program (customer supplied program) and combines
