DATA SHEET
MOS INTEGRATED CIRCUIT
µPD750064, 750066, 750068, 750064(A), 750066(A), 750068(A)
4-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD750068 is one of the 75XL Series 4-bit single-chip microcontrollers and has a data processing capability
comparable to that of an 8-bit microcontroller.
The µPD750068 provides more CPU functions compared to the 75X Series and realizes high-speed operation
at the low voltage of 1.8 V, making it ideal for battery-driven applications. This device has on-chip A/D converters,
and sophisticated timers capable of operating as a 16-bit timer. The µPD750068(A) has a higher reliability than
the µPD750068.
A version with on-chip one-time PROM, µPD75P0076, is also available for the evaluation during system
development or for small-scale production.
Detailed function descriptions are provided in the following user’s manual. Be sure to read
the document before designing.
µPD750068 User’s Manual: U10670E
Features

8-bit resolution × 8 channels
O Small packages (shrink SOP, shrink DIP)
O Uses instructions of 75X Series for easy replacement
Applications
O µPD750064, 750066, 750068
Cordless phones, audio-visual equipment, home appliances, office machines, fitness machines, meters, gas
ranges, etc.
O µPD750064(A), 750066(A), 750068(A)
Electrical equipment for automobiles
The µPD750064, 750066, 750068 and µPD750064(A), 750066(A), 750068(A) differ only in quality grade. In
this manual, the µPD750068 is described as typical product unless otherwise specified.
Users of other than the µPD750068 should read the µPD750068 as referring to the pertinent product.
When the description differs among the µPD750064, 750066, and 750068, they also refer to the pertinent (A)
products.
µPD750064 → µPD750064(A), µPD750066 → µPD750066(A), µPD750068 → µPD750068(A)
