MOS INTEGRATED CIRCUIT

µPD75064, 75066, 75068,

75064(A), 75066(A), 75068(A)

4-BIT SINGLE-CHIP MICROCOMPUTER

The µPD75068 is a member of the 75X series of 4-bit single-chip microcomputers.

The minimum instruction execution time of the µPD75068's CPU is 0.95 µs. In addition to this high-speed

capability, the chip contains an A/D converter and furnishes high-performance functions such as the serial

bus interface (SBI) function compliant with the NEC standard format, providing powerful features and high

cost performance. The µPD75068(A) is a high-reliability version of the µPD75068.

NEC also provides PROM versions suitable for small-scale production or evaluation samples in system

development. The µPD75P068 is the PROM version for the µPD75064, 75066, 75068, and the µPD75P068(A)

is that for the µPD75064(A), 75066(A), 75068(A).

The detailed function descriptions are described in the document below. Please make sure to read this

document before starting design.

µPD75068 User's Manual: IEU-1366

FEATURES
