■ DESCRIPTION

The E0C621C is a single-chip microcomputer made up of the 4-bit core CPU E0C6200A, ROM, RAM, remote

controller, R/F converter, SVD circuit, LCD driver, watchdog timer and time base counter. The E0C621C is most

suitable for remote controllers with temperature measurement functions, such as a remote control unit for an air

conditioner.
