Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

To all our customers
Cautions
Keep safety first in your circuit designs!
1.
Renesas Technology Corporation puts the maximum effort into making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire
or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i)
placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or
mishap.

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

Cautions about Operation
The mask ROM and ZTATTM versions have been confirmed as fully meeting the reference values for
electrical characteristics shown in this data sheet. However, actual performance figures, operating margins,
noise margins, and other properties may vary due to differences in the manufacturing process, internal

wiring patterns, etc. Users are therefore requested to confirm the operation of individual products by
conducting evaluation tests under conditions equivalent to those in the actual application system.
