www.DataSheet4U.com HD404669 Series Low-Voltage AS Microcomputers with On-Chip DTMF Generation Circuit ADE-202-083B Rev. 3.0 Sept. 1999 Description The HD404669 Series microcomputers incorporate a DTMF generation circuit, two comparators, and a serial interface on chip. They also provide input and output pins with large current handling capacities. Thus they are 4-bit single-chip microcomputers that are optimal for use in multifunction telephones, cordless telephones, and other communications equipment. HD404669 Series microcomputers have a 32.768 kHz sub-oscillator for realtime clock use, providing a time counting facility, and a variety of power supply modes to reduce current drain.
