Renesas’ Unique Chip Transforms Factory Automation

Renesas Electronics Corporation has introduced RZ/T2M motor control microprocessor units (MPUs) for applications such as AC servo drives and industrial robots.

To illustrate, the high-performance RZ/T2M combines fast and highly precise real-time motor control capabilities. In addition, it comes with the latest industrial Ethernet and supports functional safety operation.

The RZ/T2M enables customers to reduce the number of external components, thereby decreasing bill-of-material costs and product size. Thus, the latest MPU from Renesas provides all essential peripheral functions for motor control.

Toshihide Tsuboi, Renesas’ Vice President of Industrial Automation Business noted the growing demand for factory automation and industrial robots.

“The RZ/T2M can control the servo motors that drive robots at extremely high speed and with high precision. I anticipate it will contribute to widespread adoption of sophisticated industrial robots that can work safely alongside humans,” said Tsuboi.

Boost Realtime Control Performance

Built around two Arm Cortex-R52 cores, the RZ/T2M comes with a maximum operating frequency of 800MHz. Moreover, connecting the peripheral functions to the bus enables the CPU to access these functions with low latency. In addition, the large memory capacity in the CPU reduces fluctuation in execution time.

Thus, these features enable the RZ/T2M to deliver rapid and highly precise control, such as those for AC servos, inverters, and industrial robots.

Furthermore, 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 Networking (TSN) standard. That is, allowing multiple devices to operate in precise synchronization.

Support Functional Safety

In most cases, building industrial equipment that complies with functional safety requirements involves the addition of two external MCUs for safety monitoring, which increases BOM costs. The RZ/T2M has a hardware configuration designed with functional safety operation in mind, so only one external MCU is needed to implement functional safety. The RZ/T2M can perform functional safety operation in parallel with motor control and network communication.

In addition, Renesas plans to release later this year functional safety solutions. These include a SIL3-certified software kit combination with a self-test software kit. Also included is a SIL3 system software kit for mutual diagnosis and software isolation functionality.

Furthermore, the solutions for release also include IAR Embedded Workbench for Arm Functional Safety Edition. This acts as integrated development environment for functional safety-related development.

Renesas offers “Winning Combination” for Motor Control System with Industrial Network and Functional Safety. That is, it combines the RZ/T2M with complementary Renesas components that work together seamlessly. This includes a high-precision current detection solution combining the RZ/T2M with an isolated ΔΣ modulator. In addition, a high-precision rotational position detection solution combining the RZ/T2M with an RS-485 device and photocouplers. Finally, the combination also includes a functional safety solution of RZ/T2M with an MCU for mutual monitoring, and an optimized power supply configuration.

Renesas offers more than 300 “Winning Combinations” with compatible devices from the Renesas product portfolio to enable customers to speed up the design process and bring products to market more quickly.
