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.

HD404369 Series
Rev. 6.0
Sept. 1998
Description
The HD404369 Series is a 4-bit HMCS400-Series microcomputer designed to increase program
productivity and also incorporate large-capacity memory. Each microcomputer has an A/D converter, input
capture timer, 32-kHz oscillator for clock, and four low-power dissipation modes.
The HD404369 Series includes nine chips: the HD404364, HD40A4364 with 4-kword ROM; the
HD404368, HD40A4368 with 8-kword ROM; the HD4043612, HD40A43612 with 12-kword ROM; the
HD404369, HD40A4369 with 16-kword ROM; the HD407A4369 with 16-kword PROM.
The HD40A4364, HD40A4368, HD40A43612, HD40A4369, and HD407A4369 are high speed versions
(minimum instruction cycle time: 0.47
µs).
The HD407A4369 is a PROM version (ZTAT™ microcomputer). A program can be written to the PROM
by a PROM writer, which can dramatically shorten system development periods and smooth the process
from debugging to mass production. (The ZTAT™ version is 27256-compatible.)
