Renesas Electronics released RZ/T2M motor control MPU to realize fast and high-precision control of servo motor

     Renesas Electronics, a global semiconductor solution supplier, announced the launch of Rexa's high-performance RZ/T2M motor control microprocessor unit (MPU), which is used in AC servo drives, industrial robots and other fields. RZ/T2M combines fast, high-precision real-time motor control capability and support for the latest industrial Ethernet protocol on a single chip, while realizing functional safety operation. By providing all necessary peripheral functions for motor control, RZ/T2M can significantly reduce the number of external components for users, thereby reducing BOM cost and product size.

     Junxiu Hirai, Vice President of Rexa Electronics Industrial Automation Business Unit, said: "In order to improve productivity, the demand for factory automation and industrial robot deployment is growing. RZ/T2M can control the servo motor driving the robot at an ultra-high speed and accuracy. I expect it will help the development of complex industrial robots, and widely promote the common safe cooperation between machines and humans."

     RZ/T2M is built on two Arm Cortex-R52 cores, and the maximum operating frequency is 800MHz. Peripheral functions for motor control are connected to a dedicated bus directly connected to the CPU, allowing the CPU to access these functions with low latency. In addition, the large capacity (576 KB) memory is closely combined with the CPU to reduce the execution time jitter that may occur when using cache memory, so as to achieve deterministic fast response processing. These advantages enable RZ/T2M to bring fast and high-precision control for applications requiring high performance such as AC servo, frequency converter and industrial robot.

     In addition to the main industrial network protocols such as EtherCAT, PROFINET RT and EtherNet/IP, Rexa has added support for the PROFINET IRT protocol in RZ/T2M. The new MPU is also equipped with an Ethernet switch that supports the next generation time sensitive network (TSN) standard, allowing multiple devices to accurately synchronize.

     In most cases, building industrial equipment that meets functional safety requirements requires adding two external MCUs for safety monitoring, resulting in an increase in BOM costs. The hardware configuration of RZ/T2M takes functional safety operation into consideration in design, and only one external MCU is required to achieve functional safety. RZ/T2M can perform functional safety operation in parallel with motor control and network communication. In addition, Renesa plans to release functional security solutions later this year, including SIL3 certified software suite combinations. It includes a self-test software suite that enables RZ/T2M to self diagnose faults, and a SIL3 system software suite for mutual diagnosis and software isolation functions. IAR Embedded Workbench for Arm Functional Safety Edition, as an integrated development environment certified for functional safety related development, is an important tool for deploying the above software. It will support new RZ/T2M processors.

     Anders Holmberg, chief technology officer of IAR Systems, said: "Functional safety is still an important requirement for many of our users. Companies that choose Rexa's new RZ/T2M products in the future design can be confident in IAR Systems. We will provide support for IAR Systems globally with certified development tools and professional technology, thus greatly reducing users' design time and project costs."

     Renesas combines RZ/T2M with its supporting and seamless components to create a "successful product portfolio" of motor control systems with industrial networks and functional safety support. Including connecting RZ/T2M with isolated type ΔΣ High precision current detection solution combining modulator, high precision rotary position detection solution combining RZ/T2M with RS-485 equipment and optocoupler, functional safety solution combining RZ/T2M with MCU for mutual monitoring, and optimized power supply configuration. Based on multiple products that can work seamlessly, Renesa has launched more than 300 "successful product combinations" for various applications and end products to help users accelerate the design process and shorten the time to market
