DATA SHEET
MOS INTEGRATED CIRCUIT
µPD753104, 753106, 753108
4-BIT SINGLE-CHIP MICROCONTROLLER
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 (12 x 12 mm), 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.
For detailed function descriptions, refer to the following user’s manual. Be sure to read the document
before designing.
µPD753108 User’s Manual: U10890E
Features
Low voltage operation: VDD = 1.8 to 5.5 V
• Can be driven by two 1.5-V batteries
On-chip memory
• Program memory (ROM):
4096 x 8 bits (µPD753104)

• 122 µs (@ 32.768 kHz with subsystem clock)
Internal programmable LCD controller/driver
Small package:
64-pin plastic QFP (12 x 12 mm, 0.65-mm pitch)
One-time PROM version: µPD75P3116
Application
Remote controllers, cameras, hemadynamometers, electronic scale, gas meters, etc.
Unless otherwise indicated, references in this data sheet to the µPD753108 mean the
