DATA SHEET
MOS INTEGRATED CIRCUIT
µPD78P0308, 78P0308Y
8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD78P0308 and 78P0308Y are members of the µPD780308 and 780308Y Subseries of the 78K/0 Series,
in which the on-chip mask ROM of the µPD780308 and 780308Y is replaced with a one-time PROM.
Because this device can be programmed by users, it is ideally suited for system evaluation, small-scale and
multiple-device production, and early development and time-to-market.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
µPD780308, 780308Y Subseries User’s Manual: U11377E
78K/0 Series Instructions User’s Manual:
U12326E
FEATURES
Pin-compatible with mask ROM version (except VPP pin)
Program memory (one-time PROM): 60 KBNote
Internal high-speed RAM:
1024 bytes
