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.
