Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric 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 Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi 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.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

Mitsubishi Microcomputers
M16C/80 group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
------Table of Contents------
Description
The M16C/80 group of single-chip microcomputers are built using the high-performance silicon gate CMOS
process using a M16C/80 Series CPU core and are packaged in a 100-pin and 144-pin plastic molded
QFP. The peripheral functions of 100-pin and 144-pin are common. These single-chip microcomputers
operate using sophisticated instructions featuring a high level of instruction efficiency. With 16M bytes of
address space, they are capable of executing instructions at high speed. They also feature a built-in multi-
plier and DMAC, making them ideal for controlling office, communications, industrial equipment, and other
high-speed processing applications.
