µPD75328
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75328 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 µs minimum instruction execution time for the CPU, the
µPD75328 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 µPD75P328 with one-time PROM, which is replaced with the internal mask ROM for a µPD75328,
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."
"µPD75328 User's Manual: IEM-5045"
FEATURES
• Capable of high-speed operation and variable instruction execution time to power save
• 0.95 µs, 1.91 µs, 15.3 µs (Main system clock: operating at 4.19 MHz)
• 122 µs (Subsystem clock: operating at 32.768 kHz)
• 75X architecture comparable to that for an 8-bit microcomputer is employed
• Built-in programmable LCD controller/driver
• Built-in 8-bit resolution A/D converter: 6 channels
• Clock operation at reduced power dissipation: 5 µA TYP. (operating at 3 V)
• Timer function: 3 channels

• Pull-up resistors can be provided for 35 I/O lines
• Built-in NEC standard serial bus interface (SBI)
APPLICATIONS
Cameras, blood pressure gauges, airconditioners, etc.
