DATA SHEET
MOS INTEGRATED CIRCUIT
µPD753104, 753106, 753108
4-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD753108 is one of the 75XL Series 4-bit single-chip microcontroller chips and has a data processing
capability comparable to that of an 8-bit microcontroller.
The existing 75X Series containing an LCD controller/driver supplies an 80-pin package.
The µPD753108 supplies a 64-pin package, which is suitable for small-scale systems.
It features expanded CPU functions and can provide high-speed operation at a low supply voltage of 1.8 V
compared with the existing µPD75308B.
Detailed function descriptions are provided in the following user’s manual. Be sure to read it before
designing.
