MPUs Support HIPERFACE DSL Digital Encoder Interface For AC Servo Applications


Renesas has unveiled a new solution package for its RZ/T1 microprocessors (MPUs) which supports the HIPERFACE DSL digital encoder interface for AC servo applications.

The support of HIPERFACE DSL for RZ/T1 reduces the customer’s system bill-of-materials (BOM) cost and enables faster time-to-market, according to the company.

The RZ/T1 MPUs are built around the Arm Cortex-R4 processor with a dual precision floating-point unit (FPU) operating at up to 600 megahertz (MHz). They also provide: real-time processing, tightly-coupled memory, high-speed analog to support dual servo motors, and network connectivity for distributed motion that matches the needs of precise AC servo drive applications.

“The RZ/T1 already supports other leading encoder interfaces including EnDat 2.2, BiSS-C, Tamagawa and A-formatTM. This time, the RZ/T1 newly supports the HIPERFACE DSL digital encoder interface. These digital, bidirectional interfaces provide precise position values from absolute encoders. Instead of using a separate FPGA or ASIC, integrating these encoder interfaces on the RZ/T1 reduces the component count and cuts system costs”, stated the company in the announcement.


The HIPERFACE DSL interface is provided by SICK STEGMANN GmbH, and uses the familiar RS485 cabling with a transmission rate of 9.375 mega baud rate. The data is transmitted in synchronization with the drive cycle, and the cable between the drive electronic and feedback system can be up to 100 meters in length.

Renesas said that the solution package for HIPERFACE DSL provides all required support to connect the RZ/T1 to corresponding slave devices, including Encoder interface configuration data, sample driver code and documentation.

“The availability of HIPERFACE DSL for the RZ/T1 proliferates the adoption of our powerful encoder technology in the market,” said Clemens Bitsch, Product Manager of HIPERFACE DSL, SICK STEGMANN GmbH. “We see the digital encoder evolution as a substantial driver for efficient and cost-optimized systems and as a pre-requisite for the Industry 4.0.”
