4 BIT SINGLE-CHIP MICROCOMPUTER
The
碌
PD75518(A) is a 75X series four-bit single-chip microcomputer which enables data processing
equivalent to that performed by an eight-bit microcomputer. It is a high-performance product, whose
minimum instruction execution time is 0.67
碌
s, shorter than 0.95
碌
s for the conventional
碌
PD75516. The ROM
and RAM capacities are also larger, and the throughput of the 75X series is further increased. The
碌
PD75517(A)
is suited to controllers of electric parts of automobiles.
