DATA SHEET
4-BIT SINGLE-CHIP MICROCOMPUTER
The
μ
PD75068 is a member of the 75X series of 4-bit single-chip microcomputers.
The minimum instruction execution time of the
μ
PD75068's CPU is 0.95
μ
s. 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
μ
PD75068(A) is a high-reliability version of the
μ
PD75068.
NEC also provides PROM versions suitable for small-scale production or evaluation samples in system
development. The
μ
PD75P068 is the PROM version for the
μ
PD75064, 75066, 75068, and the
μ
PD75P068(A)
is that for the
μ
PD75064(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.
