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.
The HD407A4669 is a ZTAT
microcomputer with on-chip PROM that drastically shortens development
time and ensures a smooth transition from debugging to mass production. (The PROM programming
specifications are the same as for the 27256 type.)
