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.

When exporting the products or technology described in this document, you should comply with the applicable export control
laws and regulations and follow the procedures required by such laws and regulations. You should not use Renesas
Electronics products or the technology described in this document for any purpose relating to military applications or use by
the military, including but not limited to the development of weapons of mass destruction. Renesas Electronics products and
technology may not be used for or incorporated into any products or systems whose manufacture, use, or sale is prohibited
under any applicable domestic or foreign laws or regulations.
Renesas Electronics has used reasonable care in preparing the information included in this document, but Renesas Electronics
does not warrant that such information is error free. Renesas Electronics assumes no liability whatsoever for any damages
incurred by you resulting from errors in or omissions from the information included herein.
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.
This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written consent of Renesas

M16C/28 Group (M16C/28, M16C/28B)
SINGLE-CHIP 16-BIT CMOS MCU
REJ03B0201-0050
Rev.0.50
2006.09.15
1. Overview
The M16C/28 Group (M16C/28 and M16C/28B) MCU are single-chip control MCU, fabricated using high-
performance silicon gate CMOS technology with the M16C/60 series CPU core. The M16C/28 Group
(M16C/28 and M16C/28B) are housed in 64-pin and 80-pin plastic molded LQFP packages and also in 85-
pin plastic molded TFLGA (Thin Fine Pitch Land Grid Array) package. With a 1-Mbyte address space, this
MCU combines advanced instruction manipulation capabilities to process complex instructions by less
bytes and execute instructions at higher speed. It includes a multiplier and DMAC adequate for office
automation, communication devices and other high-speed processing applications.
The M16C/28 has Normal-ver., T-ver., and V-ver.. The M16C/28B has Normal-ver. only.
This hardware manual describes the Normal-ver. only. Please contact Renesas Technology Corp. for
T-ver./V-ver. information.
1.1 Applications
Audio, cameras, office equipment, communication equipment, portable equipment, home appliances (in-
verter solution), motor control, industrial equipment, etc.
