This product can support 5V power supplies. The advantage of 5V MCU is higher noise immunity than a 3V MCU, so 5V products are less likely to malfunction. Currently, customers use many components for noise suppression to prevent malfunctions. A customer who is a home appliance maker said that the BOM cost for noise countermeasures is more than the price of the MCU. By using a 5V MCU, the total BOM cost can be lowered because the number of components can be reduced. Also, the dynamic range of AD conversion is 1.7 times larger than that of a 3V MCU, so digital conversion is possible with high accuracy even when affected by noise. In the future, more and more customers will want to use high-precision detection, since sensors are increasing in system control for fault detection and other applications. Competitors products have few 5V MCU lineups, so if there is a 5V requirement, the RX660 has one of the best performances.
