Renesas Electronics Corporation introduced the ASI4U-V5 ASSP – the industry’s first silicon solution to fully implement the ASi-5 (Actuator Sensor Interface version specification version 5) standard for industrial network equipment. ASi-5 offers superior performance and usability over ASi-3, delivering 1.27 ms cycle time, 200m cable length and 96 slaves per segment. The field-proven ASSP delivers an easy-to-use fieldbus integration option for developers working with sensors, actuators, and other industrial equipment requiring easy and cost-efficient fieldbus connectivity.

The new ASI4U-V5 ASSP features a fully verified and field-proven firmware that reduces the complexity associated with ASi-5 implementations, allowing users to minimize design risks. The ASSP is fully backwards compatible with ASi-3 devices while incorporating the shorter cycle times, higher bandwidth resulting from the use of Orthogonal Frequency Division Multiplexing (OFDM), enhanced diagnostics, and state-of-the-art robustness associated with the ASi-5 standard. The ASSP also supports all bus topologies, including line, star, and tree. Users can also take advantage of easy and cost-efficient integration with other industrial protocols such as IO-Link and HART.

“As the digital transformation wave sweeps across industrial factories and production facilities, the ASi-5 interface constitutes the shuttle into digitization for millions of connected industrial endpoints and devices at the edge,” said Niels Trapp, Senior Director of Industrial Automation Business Division at Renesas. “The tight collaboration of Renesas and its ASi-5 development partners proved to be extraordinarily successful, and we are excited to bring the first ASi-5 silicon solution to market and enable faster transmission of larger data quantities and more efficient integration with smart sensors that are becoming an integral part of the Industrial IoT.”
