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 / 6N0 / 6N1 Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Description
------Table of Contents------
Description
The M16C/6N 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 plastic molded QFP.
These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruc-
tion 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/6N group is consisted of two sub-groups, M16C/6N0 group and M16C/6N1 group. The M16C/
6N0 group has two CAN (Controller Area Network) modules and the M16C/6N1 group has one CAN mod-
ule (See Figure 1.1.4 Memory Expansion). The CAN modules comply with the 2.0B specification. The
M16C/6N group is suited to drive automotive and industrial control systems.
