To all our customers
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.

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.

HD404374/HD404384/
HD404389/HD404082/HD404084 Series
Low-Voltage AS Microcomputers with On-Chip A/D Converter
ADE-202-086C (O)
Rev. 4.0
Feb. 2000
Description
The HD404374, HD404384, and HD404389 Series comprise low-voltage, 4-bit single-chip
microcomputers equipped with four 10-bit A/D converter channels, a serial interface, and large-current I/O
pins. These devices are suitable for use in applications requiring high resolution A/D converter control,
such as battery chargers.
The HD404082 and HD404084 series offer less advanced features than the HD404384 series. They are 4-
bit microcomputers that support low-voltage operation for backward software compatibility.
HD404374 Series microcomputers have a 32.768 kHz sub-resonator for realtime clock use, providing a
time counting facility, and a variety of low-power modes to reduce current drain.
The HD407A4374, HD407A4384, HD407A4389, HD407C4374, HD407C4384, and HD407C4389 are
ZTAT
TM
microcomputers 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.)

Cautions about operation!
•
Electrical properties presented on the data sheet for the mask ROM and ZTAT
TM
versions will surely
and sufficiently satisfy the standard values. However, real capabilities, operation margin, noise margin,
and other properties may vary depending on differences of manufacturing processes, internal wiring
patterns, etc. Therefore, it is requested for users to carry out an evaluation test for each product on an
actual system under the same conditions to see its operation.
•
After power supply has been connected, the values for the memory register, data and stack areas will be
undefined. Initialize prior to use.
