HMCS47CL(HD44868)
The HMCS47C is the CMOS 4·bit single chip microcomputer
which contains ROM, RAM, I/O and Timer/Counter on single
chip. The HMCS47C is designed to perform efficient controller
function as well as arithmetic function for both binary and BCD
data. The CMOS technology of the HMCS47C provides the
flexibility of microcomputers for battery powered and battery
back·up applications.
