By providing all the essential peripheral functions for motor control, the RZ/T2M allows customers to reduce the number of external components, thereby lowering bill of materials costs and product size.
The RZ/T2M is built around two Arm® Cortex®-R52 cores with a maximum operating frequency of 800 MHz. Connecting the peripheral functions used for motor control to a dedicated bus directly linked to the CPU allows the CPU to access these functions with low latency. Furthermore, the large memory capacity (576 KB) is tightly coupled to the CPU, reducing runtime jitter that can occur when using cache memory and delivering fast, deterministic processing. These advantages enable the RZ/T2M to provide fast and highly accurate control for high-performance applications such as AC servos, inverters, and industrial robots.
In addition to major industrial networking protocols such as EtherCAT, PROFINET RT, and EtherNet/IP, Renesas has added support for the PROFINET IRT protocol in the RZ/T2M. The new MPU also includes an Ethernet switch that supports the next-generation Time Sensitive Network (TSN) standard, enabling multiple devices to operate with precise synchronization.
In most cases, building industrial equipment that meets functional safety requirements involves incorporating two external MCUs for safety monitoring, increasing bill of materials costs. The RZ/T2M has a hardware configuration designed with functional safety in mind, so only one external MCU is needed to implement functional safety. The RZ/T2M can perform functional safety operations in parallel with motor control and network communication. Furthermore, Renesas plans to launch functional safety solutions later this year, including a combination of SIL3-certified software kits. These kits include a self-test software kit that enables the RZ/T2M to self-diagnose faults, and an SIL3 system software kit for mutual diagnosis and software isolation functionality. The IAR Embedded Workbench for Arm Functional Safety Edition, a certified integrated development environment for functional safety-related development and an essential tool for deploying the aforementioned software, will be compatible with the new RZ/T2M processors.
