HD404669 General 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.)
ZTAT™: Zero Turn-Around Time ZTAT is a trademark of Hitachi, Ltd.

Notes: 1. Applies to D13 (VPP) of the HD407A4669.
2. The total permissible input current is the total of input currents simultaneously flowing in from all the I/O pins to ground.
3. The total permissible output current is the total of output currents simultaneously flowing out from VCC to all I/O pins.
4. The maximum input current is the maximum current flowing from each I/O pin to ground.
5. Applies to D0D3, R0R4 and R6RA.
6. Applies to D4, D5 and D9D11
7. The maximum output current is the maximum current flowing out from VCC to each I/O pin.
8. Applies to D4, D5, D9D11, R0R4 and R6RA.
9. Applies to D0D3.
10. The operating temperature indicates the temperature range in which power can be supplied to the LSI (voltage VCC shown in the electrical characteristics tables can be applied).
11. In the case of chips, the storage specification differs from that of the package products. Please
consult your Hitachi sales representative for details.
