MOS INTEGRATED CIRCUIT

µPD75402A(A)

4 BIT SINGLE-CHIP MICROCOMPUTER

The µPD75402A(A) is a CMOS single-chip microcomputer which uses the 75X series architecture. It operates

at high speed with a minimum instruction execution time of 0.95 µs.

The µPD75P402 is also available for system development evaluation. It contains one-time PROM instead

of mask ROM used in the µPD75402A(A).

The following user's manual describes the details of the functions of the µPD75402A(A). Be sure to read

it before designing an application system.

µPD75402A User's Manual: IEU-644

FEATURES

• More reliable than the µPD75402A

• High-speed operation with a minimum instruction execution time of 0.95 µs (when the microcomputer

operates at 4.19 MHz)

• Low voltage and low-speed instruction execution time of 15.3 µs (when the microcomputer operates at

4.19 MHz)

• Memory mapping by on-chip peripheral hardware

• NEC standard serial bus interface (SBI)

• 8-bit basic interval timer (watchdog timer applicable)

• Interrupt function

•

Three vectored interrupts (one external and two internal interrupts)

One external test input

• Clock output function (remote controller output applicable)

• Capable of specifying the incorporation of 16 pull-up resistors by software

APPLICATIONS

Electronic units for automobiles, and suchlike
