HMCS44C(HD44801 )
HMCS44CL(HD44808)
The HMCS44C is the CMOS 4-bit single chip microcomputer
which contains ROM, RAM, 110 and Timer/Event Counter on
single chip. The HMCS44C is designed to perform efficient con-
troller function as well as arithmetic function for both binary and
BCD data. The CMOS technology of the HMCS44C provides the
flexibility of microcomputers for battery powered and battery
back-up applications.
