µ

PD75064, 75066, 75068,

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

4-BIT SINGLE-CHIP MICROCOMPUTER

MOS INTEGRATED CIRCUIT

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.
