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 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.
