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.

M16C / 62T Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
------Table of Contents------
Description
The M16C/62T group of single-chip microcomputers are built using the high-performance silicon gate
CMOS process using a M16C/60 Series CPU core and are packaged in a 100-pin or a 80-pin plastic
molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high
level of instruction efficiency. With 1M bytes of address space, they are capable of executing instructions at
high speed. They also feature a built-in multiplier and DMAC, making them ideal for controlling office,
communications, industrial equipment, and other high-speed processing applications.
The M16C/62T group includes a wide range of products with different internal memory types and sizes and
various package types.
