The MCU lineup of Renesas includes the RX23T Group with built-in floating-point unit (FPU) suitable for vector control, and the RL78/G14 Group capable of vector control even at low pin counts, which are suitable for inverter control in refrigerator applications. Their on-chip features allow the design of efficient motor drive solutions which allow refrigerators to be made more eco-friendly. For refrigerator system control, the RL78/G13 Group, the RX230 Group, and the RA4M1 Group are ideal product groups in that they incorporate a variety of A/D converters to allow precise control of the internal temperature. In addition, the RX130 Group, the RX230 Group, the RX651 Group and the RA4M1 Group and the RA2L1 Group MCU is designed to implement a touch panel solution which allows the appliance manufacturer to provide flat panel interfaces free of protrusions or indentations, thus improving cleaning and maintenance.
