Renesas – R-IN32M3 Series: Real-time industrial networking begins with R-IN



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/IP™, Modbus® TCP and others. The challenge is in designing a cost-effective platform to support these multiple protocols, as well as integrate 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 applicationspecific 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.
