Renesas – Real-time industrial networking begins with R-IN

Renesas RIN
The growing demand to network industrial systems and processes to improve operational efficiencies and reduce cost, has driven the use of Ethernet-based protocols such as EtherCAT®, CC-Link® IE, PROFINET®, Ethernet/ IPTM, Modbus® TCP and others. The challenge is in designing a cost-effective platform to support these multiple protocols, as well as integrating a highly-efficient processor subsystem to manage complex real-time operation.

Renesas facilitates this system-level need with the R-IN32M3 multi-protocol industrial networking platform application-specific standard product (ASSP). Customers integrating the R-IN32M3 into their devices can achieve up to a 5X improvement* in overall network performance using optimized hardware accelerators targeted at reducing packet handling overhead and RTOS management.
