PD75048
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
碌
PD75408 is a 4-bit single-chip microcomputer whose data processing capability is comparative to that
of an 8-bit microcomputer.
The
碌
PD75048 employs a CPU whose minimum instruction execution time is 0.95
碌
s, and contains the
EEPROM, A/D converter, multi-function timer, and high performance hardware to provide high cost to
performance ratio.
Detailed functions are described in the following user's manual. Read this manual when designing your
system.
