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 µPD75068s 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).

FEATURES
