Renesas bundles real-time motor control and Linux onto a single industrial chip

Renesas has launched its RZ/T2N industrial microprocessor, designed to consolidate multiple industrial control functions into a single silicon package. It combines up to two 1.2 GHz Cortex-A55 cores for running general-purpose applications like Linux with two 800 MHz Cortex-R52 cores dedicated to hard real-time tasks. The chip directly supports controlling up to four motor axes and integrates a gigabit Ethernet switch with Time-Sensitive Networking (TSN) and major industrial protocols like EtherCAT and PROFINET.

For engineers building industrial robots, PLCs, or servo drives, this integration means simplifying system design by eliminating separate processors for networking, real-time control, and application hosting. The MPU can act as either a network controller or an endpoint device, offering flexibility. The takeaway is a significant step towards more compact, efficient, and cost-effective industrial automation hardware, directly addressing the convergence of IT and operational technology.
