Our comprehensive Human Machine Interface (HMI) solutions offer a robust suite of hardware, software, and tools to streamline development, helping users to create intuitive, responsive interfaces for a wide range of applications. From touchscreens and voice control to gesture recognition and haptics, Renesas provides the technologies to enhance user interaction and deliver cutting-edge experiences.
The RX MCUs for inverter control incorporate motor control timers and other built-in functions for inverter control that were cultivated in previous products such as the SH controllers and the H8SX MCUs. They support the 5V power supply that is required by many industrial applications, and are also equipped with a comprehensive set of analog functions such as 12-bit analog-to-digital (A/D), 3-channel simultaneous sampling hold circuit, programmable gain amplifier (PGA), and a comparator.
The rise of smart technologies and connected ecosystems, along with stricter regulations, drives manufacturers to prioritize security. Developers face tight budgets and timelines while building efficient, secure solutions. The RX Family meets these needs with hardware-based security, including isolated cryptographic operations and secure key storage.
The IoT market continues to rapidly expand in Industrial IoT, smart homes, and smart cities. To accelerate IoT product development and enable Over-the-Air (OTA) firmware updates, the RX family offers IoT evaluation kits, development environments (e² studio), and a development assistance tool (QE for OTA). An optimized sensor measurement solution is also available to meet the needs of IoT.
Seamless real-time communication is the core prerequisite for all Industry 4.0 and Industrial Internet of Things (IIoT) implementations. We offer best-in-class communication components and comprehensive software support for all leading industrial communication protocols, including but not limited to PROFINET, EtherNet/IP, EtherCAT, Modbus, and CC-Link.
We support RX Family development with IDEs, real-time OS, middleware, and tools. Paired with evaluation kits, they simplify coding, building, and debugging, reducing system development time.
