4-BIT SINGLE-CHIP MICROCOMPUTER
The mark

shows the major revised points.
DESCRIPTION
The
μ
PD75328 is one of the 75X Series 4-bit single-chip microcomputer, and has a data processing
capability comparable to that of an 8-bit microcomputer.
In addition to high-speed operation with 0.95
μ
s minimum instruction execution time for the CPU, the
μ
PD75328 can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microcomputer
chip having a built-in LCD controller/driver and A/D converter, its data processing capability is the highest
in its class in the world.
The
μ
PD75P328 with one-time PROM, which is replaced with the internal mask ROM for a
μ
PD75328,
is applicable for evaluating systems under development, or for small-scale production of developed
systems.
"Detailed functions are described in the following user's manual. Be sure to read it for designing."
