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
