RX24U
The RX24U Group features a 32-bit microcontroller ideally suited for dual inverter control with a built-in Floating-Point Unit (FPU) that enables it to easily execute complex inverter control algorithms. The built-in Differential Programmable Gain Amplifier and the provide safety system allow to bring application system cost down.
Products with the operating ambient temperature of 105 °C are also available.
The easy usability of the RX24U is helping our customers to reduce the time to market by reducing software development efforts and system design by providing a ready-to-go motor control solution, including software and hardware design examples.
