RX24U

Powerful 32-bit Motor Control MCU with built-in differential amplifiers and safety systems.

 

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.

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.
