DATA SHEET
MOS INTEGRATED CIRCUIT
µPD75312(A), 75316(A)
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD75316(A) is one of the 75X Series 4-bit single-chip microcomputer having a built-in LCD controller/
driver, 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
µPD75316(A) 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 panel controller/driver, its data processing capability is the highest in its class in
the world.
Detailed functions are described in the following user's manual. Be sure to read it for designing.
µPD75308 User's Manual: IEM-5016
FEATURES
Higher reliability than µPD75316
Internal memory
• Program memory (ROM)
: 16256 × 8 bits (µPD75316(A))
: 12160 × 8 bits (µPD75312(A))
• Data memory
: 512 × 4 bits
Capable of high-speed operation and variable instruction execution time to power save
• 0.95 µs, 1.91 µs, 15.3 µs (operating at 4.19 MHz)
• 122 µs (operating at 32.768 kHz)
75X architecture comparable to that for an 8-bit microcomputer is employed
Built-in programmable LCD controller/driver
Clock operation at reduced power dissipation: 5 µA TYP. (operating at 3 V)
Enhanced timer function (3 channels)
Interrupt functions especially enhanced for applications, such as remote control receiver
Pull-up resistors can be provided for 31 I/O lines
Built-in NEC standard serial bus interface (SBI)
Upgraded model of µPD7514 (µPD7500 Series)
PROM version (µPD75P316, µPD75P316A) available
APPLICATIONS
Suitable for controlling automotive and transportation equipment.
The µPD75316(A) is treated as the representative model throughout this document,
unless there are differences between µPD75312(A) and µPD75316(A) functions.
The information in this document is subject to change without notice.
