UPD75402A 4 BIT SINGLE-CHIP MICROCOMPUTER

DATA SHEET 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 .

UPD75402A Features

* More reliable than the µPD75402A
