Industrial Ethernet and multi-axis motor control solutions lineup extended

Renesas Electronics Corporation has released the RZ/T2H, the highest-performance MPU offered by the company for industrial equipment. Thanks to its powerful application processing and real-time performance, the MPU is capable of high-speed, high-precision control of industrial robot motors for up to nine axes. It supports a variety of network communications, including industrial Ethernet on a single chip. The MPU targets industrial controller equipment such as PLCs, motion controllers, DCSs, and CNCs.

With the growing demand for unmanned and labour-saving manufacturing, industrial robots such as vertically articulated robots, and industrial controller equipment are being deployed to accelerate automated production. The new MPU combines all the functionality and performance needed to develop these applications. While industrial systems traditionally need multiple MPUs or a combination of FPGAs to control these applications, the MPU can now fulfil all the needs on a single chip. This lowers the number of components and saves time and costs of FPGA program development.

“We have enjoyed outstanding market success with RZ/T2M and RZ/T2L,” said Daryl Khoo, vice president of Embedded Processing 1st Business Division at Renesas. “The RZ/T2H builds on that momentum, allowing our industrial customers to leverage their existing design assets while addressing even more innovative, demanding industrial motor control and Linux applications. Our customers have been particularly impressed that the RZ/T2H enables them to implement a 9-axis motor control all on just one chip!”

The device has four Arm Cortex-A55 application CPUs with a maximum operating frequency of 1.2GHz. For external memory, it supports 32-bit LPDDR4-3200 SDRAM. Two Cortex-R52 CPUs with a maximum operating frequency of 1GHz handle the real-time processing, with each core equipped with a total of 576KB of high-capacity tightly coupled memory (TCM). This allows high CPU and memory-intensive tasks, such as running Linux applications, robot trajectory generation, and PLC sequence processing, to be executed on a single chip. At the same time, the RZ/T2H can handle fast and precise real-time control such as motor control and Industrial Ethernet protocol processing.

The MPU controls up to nine-axis servo motors in industrial robots with high-speed and accurate operation. It comes with everything required for up to nine axes of motor control, including three-phase PWM timers, delta-sigma interfaces for measuring current values, and encoder interfaces (A-format, EnDat, BiSS, Hyperface DSL, and FA-CODER are all supported). Furthermore, peripheral functions for motor control are placed on a Low Latency Peripheral Port (LLPP) bus of the Cortex-R52 real-time CPU core, allowing high-speed access from the CPU.

The MPU has four Ethernet ports, three Gigabit Ethernet MAC (GMAC), and an Ethernet switch. It also supports EtherCAT, PROFINET, EtherNet/IP, OPC UA, and the next-generation Time-Sensitive Networking (TSN) standard. Combining these Ethernet switches and GMAC allows the MPU to support multiple Industrial Ethernet controllers and devices, providing flexibility to adapt to various controller needs, such as upper-layer Ethernet communications.

The device comes with the Renesas Flexible Software Package (FSP), as with all its MPUs, and a Linux package with long-term support. An out-of-the-box multi-axis motor control evaluation solution includes inverter boards for driving nine-axis motors, a multi-axis motor control software package, and Motion Utility Tool (a motor control software tool). Sample protocols for industrial Ethernet and software PLC package are also included to kick-start system development.

“As industrial equipment continues to evolve, these systems increasingly require more complex functions and performance,” said Micael Borgefeldt, product manager at IAR Systems. “Including the latest RZ/T2H MPU from Renesas, we empower the developers to unlock flexible application configurations across 32-bit MCUs and 64-bit high-end MPUs multi-core environments. Our IAR development solution enables engineers to accelerate next-generation industrial innovation, streamlining development and boosting efficiency like never before.”
