For engineers reviewing the R5F572MDDDFB#30 datasheet, R5F572MDDDFB#30 pinout, R5F572MDDDFB#30 application, or R5F572MDDDFB#30 equivalent, key selection criteria include EtherCAT slave timing compliance, IEEE 1588 PTP synchronization capability, dual-bank flash for safe firmware updates, 182 GPIO with 5-V tolerance, and TSIP-based AES-256 encryption support.

Technical Context

The R5F572MDDDFB#30 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (16×64-bit data registers), and collective register bank save for fast context switching. Its clock system includes PLLs supporting 240-MHz ICLK, independent PCLKA (120 MHz) for Ethernet/ESC/GPTW, and PCLKB (60 MHz) for timers and peripherals.

Real-time determinism is enabled by hardware-accelerated EtherCAT slave functionality, IEEE 1588 PTP timestamping via EPTPC, and event linking (ELC) that synchronizes timer triggers, ADC starts, and PWM dead-time compensation without CPU intervention - critical for servo drive cycle times under 100 µs.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572MDDDFB#30?

The R5F572MDDDFB#30 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's efficient instruction set, dual-issue capability for certain operations, and optimized memory subsystem - enabling complex motion control algorithms to execute within strict real-time deadlines. The R5F572MDDDFB#30 maintains this throughput while supporting double-precision floating-point math and trigonometric functions in hardware.

Does the R5F572MDDDFB#30 include an integrated EtherCAT slave controller?

Yes, the R5F572MDDDFB#30 integrates a Beckhoff-certified EtherCAT slave controller (ESC) with dual-port MII/RMII support. This hardware block handles frame processing, distributed clock synchronization, and mailbox management without CPU overhead - meeting IEC 61800-3 timing requirements for servo drives. The R5F572MDDDFB#30 does not require external ASICs or FPGAs to implement EtherCAT, reducing system complexity and bill-of-materials cost.

What analog peripherals are included in the R5F572MDDDFB#30?

The R5F572MDDDFB#30 includes two independent 12-bit A/D converters (8 channels on S12AD0, 21 channels on S12AD1), two 12-bit D/A converters, an on-chip temperature sensor, and a six-channel delta-sigma modulator interface (DSMIF). These peripherals support simultaneous sampling of motor phase currents and bus voltage, closed-loop analog feedback, and direct connection to isolated sigma-delta ADCs - all critical for high-fidelity current control in servo applications. The R5F572MDDDFB#30 also provides hardware self-diagnostic functions for ADC linearity and disconnection detection per IEC 60730.

What security features does the R5F572MDDDFB#30 offer for industrial firmware protection?

The R5F572MDDDFB#30 includes Trusted Secure IP (TSIP) with AES-128/192/256 encryption engines, secure boot verification, and key wrapping capabilities. It also implements IEC 60730 Class B self-test features such as oscillation-stoppage detection, CRC calculation acceleration (CRCA), and register write protection. These features collectively protect firmware integrity, prevent unauthorized cloning, and ensure safe operation in certified industrial equipment - fulfilling requirements for UL/IEC functional safety certification. The R5F572MDDDFB#30 leverages these blocks to enforce secure OTA updates and runtime tamper resistance.

What package type and pin count does the R5F572MDDDFB#30 use?

The R5F572MDDDFB#30 uses a 176-pin LFBGA package (PLQP0176KB-C) measuring 24 × 24 mm with 0.5-mm pitch. It provides 136 general-purpose I/O pins, including 19 pins with 5-V tolerance, configurable as open-drain outputs or with internal pull-up resistors. This package balances high I/O density with thermal and mechanical robustness for industrial PCB layouts - and is pin-compatible with other RX72M variants in the same footprint, enabling scalable design reuse across performance grades. The R5F572MDDDFB#30's pinout supports full MII/EtherCAT, dual ADC banks, and multiple high-speed serial interfaces simultaneously.
