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

• 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.
