SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
The M16C/30L 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, low voltage (2.2V to 3.6V), they are capable of executing
instructions at high speed. They also feature a built-in multiplier and DMAC, making them ideal for control-
ling office, communications, industrial equipment, and other high-speed processing applications.
The M16C/30L group includes a wide range of products with different internal memory sizes and various
package types.
