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.
