Air Conditioner (High-End)
详情介绍
Overview
Renesas offers a variety of microcontrollers for air conditioner control to realize a more comfortable living environment. The RX24T Group can control two inverters and has a built-in floating-point unit (FPU) that facilitates vector control, making it suitable for outdoor units. The RL78 Family, the RX130 Series, and the RX230 Series are designed for indoor units. The RL78/L12 Group and the RL78/L13 Group are for use in remote controls. Renesas delivers solutions optimized to customer requirements.
