4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75117H is a 75X Series 4-bit single-chip microcomputer.
The µPD75117H is a product which has the same functions as those of the µPD751××F, with the minimum
operating voltage reduced from the previous 2.7 V to 1.8 V, and achieving 1.91 µs operation at 1.8 V. There-
fore, it facilitates low-voltage operation for a set requiring high-speed operation.
Functions are described in detail in the following User’s Manual, which should be read when carrying out
design work.
