To our customers,
Old Company Name in Catalogs and Other Documents
On April 1
st
, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas
Electronics Corporation
took over all the business of both
companies.
Therefore, although the old company name remains in this document, it is a valid
Renesas
Electronics document. We appreciate your understanding.

Renesas Electronics products are classified according to the following three quality grades: “Standard”, “High Quality”, and
“Specific”. The recommended applications for each Renesas Electronics product depends on the product’s quality grade, as
indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular
application. You may not use any Renesas Electronics product for any application categorized as “Specific” without the prior
written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for
which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way
liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product for an
application categorized as “Specific” or for which the product is not intended where you have failed to obtain the prior written
consent of Renesas Electronics. The quality grade of each Renesas Electronics product is “Standard” unless otherwise
expressly specified in a Renesas Electronics data sheets or data books, etc.
Computers; office equipment; communications equipment; test and measurement equipment; audio and visual
equipment; home electronic appliances; machine tools; personal electronic equipment; and industrial robots.
“High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-
crime systems; safety equipment; and medical equipment not specifically designed for life support.
“Specific”:
Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or
systems for life support (e.g. artificial life support devices or systems), surgical implantations, or healthcare
intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.
You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,
especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation
characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or
damages arising out of the use of Renesas Electronics products beyond such specified ranges.
Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have
specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further,
Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to
guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a
Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire
control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because
the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system
manufactured by you.
Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental
compatibility of each Renesas Electronics product. Please use Renesas Electronics products in compliance with all applicable
laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS
Directive. Renesas Electronics assumes no liability for damages or losses occurring as a result of your noncompliance with
applicable laws and regulations.

HD404889/HD404899/HD404878/
HD404868 Series
Low-Voltage AS Microcomputers with On-Chip LCD Circuit
REJ03B0051-0600H
Rev. 6.00
Sep.08.2003
Description
The HD404889, HD404899, and HD404868 Series comprise low-voltage, 4-bit single-chip
microcomputers with a variety of on-chip supporting functions that include an LCD circuit, A/D converter,
multifunctional timers, and large-current I/O pins. These devices are suitable for system and display panel
control in a wide range of applications, including pagers, remote controllers, and home appliances equipped
with an LCD display.
The HD404878 Series comprises low-voltage, 4-bit single-chip microcomputers with no on-chip A/D
converter.
Each series is equipped with 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 HD4074889, HD4074899, and HD4074869 are ZTAT™ 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.)
ZTAT : Zero Turn-Around Time. ZTAT is a trademark of Renesas Technology Corp.

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.
•
Memory register, data area, and stack area values are unstable immediately after power is turned on.
They must be initialized before use.
