Refridgerator (Low-End)

Overview

The MCU lineup of Renesas includes the RL78/G14 Group and the RL78/G1F Group with built-in MCU peripheral functions such as reset IC, which provide low lost small pin-count solutions suitable for inverter control in refrigerator applications. Their on-chip features allow refrigerators to be more eco-friendly. For refrigerator system control, the RL78/G13 Group is ideal because they incorporate a variety of A/D converters to precisely control the internal temperature.
