At SPS 2019, during Renesas’ press conference, Knut Dettmer, Senior Manager-Product Marketing showcased Renesas’ updates and new solutions. Among the products presented, the new RX72M family of Microcontrollers is a combination of performance, connectivity and safety. The RX MCUs feature an EtherCAT slave controller for industrial Ethernet communication. They provide a high-performance, single-chip MCU solution with large memory capacities for industrial equipment requiring control and communication functions such as compact industrial robots, programmable logic controllers, remote I/O, and industrial gateways.
Combine a motor-control MCU with on-chip Ehtercat slave functions to reduce the bill of materials
The RX72M Group achieves the performance of a 1396 CoreMark score (Note 1) at 240MHz and is capable of both application processing and EtherCAT communication. It is the first RX MCU group to comprise an EtherCAT slave controller featuring the RX family’s highest SRAM capacity, 1 MB of SRAM and 4 MB of Flash memory. In addition, some of the key features include a high-speed flash memory system supporting readout up to 120 MHz, dedicated trigonometric function accelerators and register bank save function supporting high-precision motor control implementation, and reliable cryptography functions such as encryption module and memory protection function in hardware to protect encryption keys.
