The new Renesas RX family offers 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.
 
The new RX72M Group achieves a superior performance score of 1396 (Note 1) at 240MHz, as measured by EEMBC® Benchmarks, and is capable of both application processing and EtherCAT communication. Combining a motor control MCU with on-chip EtherCAT slave functions allows industrial application developers to reduce their bill of materials (BOM) and support the miniaturization levels required for industrial equipment design.
 
The RX72M Group is the first RX MCU group to include an EtherCAT slave controller with the highest SRAM capacity in the RX family (1 MB of SRAM) and 4 MB of Flash memory. The large-capacity SRAM allows the MCU to run multiple memory-intensive middleware systems, such as TCP/IP, web servers, and file systems, at high speed without the use of external memory. It also provides flexibility for supporting future functional expansions, such as OPC United Architecture (OPC UA, Note 2), without requiring additional memory. The onboard flash memory operates as two 2MB banks, enabling stable end-user operation, such as running a program in one flash memory while simultaneously performing background writes to the other.
 
Features
: - The first EtherCAT slave controller for industrial Ethernet communication in an RX MCU.
- High performance with a CoreMark benchmark score of 1396 at up to 240 MHz, and the first double-precision floating-point unit (FPU) integrated into an RX MCU.
High-speed flash memory system supporting reads up to 120 MHz, creating a high-performance, low-variability runtime environment.
- Dedicated trigonometric function accelerators (sin, cos, arctan, and hypothetical functions) and bank register saving function supporting high-precision motor control implementation: a feature shared with Renesas RX72T motor control MCUs.
- Reliable cryptography features, such as the encryption module and hardware memory protection function to safeguard encryption keys, preventing unauthorized copying of application systems and supporting OEM authentication.
- Flexible package options including 176-pin LQFP and 176-pin BGA configurations, as well as the first 224-pin BGA package for RX MCUs, offering additional space savings for size-constrained designs.
