1. Overview
1.1 Features
The M16C/64A Group microcomputer (MCU) incorporates the M16C/60 Series CPU core and flash
memory, employing sophisticated instructions for a high level of efficiency. This MCU has 1 MB of address
space (expandable to 4 MB), and it is capable of executing instructions at high speed. In addition, the
CPU core boasts a multiplier for high-speed operation processing.
This MCU consumes low power, and supports operating modes that allow additional power control. The
MCU also uses an anti-noise configuration to reduce emissions of electromagnetic noise and is designed
to withstand electromagnetic interference (EMI). By integrating many of the peripheral functions, including
the multifunction timer and serial interface, the number of system components has been reduced.
1.1.1 Applications
This MCU can be used in audio components, cameras, televisions, household appliances, office
equipment, communication devices, mobile devices, industrial equipment, and other applications.
