FAQ

What is the maximum operating frequency and CPU performance of the R5F571MFCDFB#30?

The R5F571MFCDFB#30 operates at a maximum system clock frequency of 240 MHz using its RXv2 CPU core and delivers 480 DMIPS of processing performance. Its single-precision IEEE-754 floating-point unit enables efficient signal processing and control algorithm execution without external coprocessors. This performance level is sustained across the full operating voltage range of 2.7–3.6 V.

Does the R5F571MFCDFB#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MFCDFB#30 includes a dedicated IEEE 1588-compliant PTP controller (EPTPCa) tightly coupled to its dual-channel Ethernet MAC (ETHERC). Hardware timestamping is performed at the MAC layer with sub-microsecond resolution, and synchronization is enhanced by integration with MTU3 and GPT timers for precise event-triggered time capture - critical for time-sensitive networking in industrial automation.

What package type and pin count does the R5F571MFCDFB#30 use?

The R5F571MFCDFB#30 uses the PLQP0176KB-A package: a 176-ball Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm pitch. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, and supports all high-speed interfaces including dual Ethernet MII, USB 2.0 HS, and QSPI - making it the highest-feature variant in the RX71M family.

How does the R5F571MFCDFB#30 support functional safety standards like IEC60730?

The R5F571MFCDFB#30 integrates multiple hardware features for IEC60730 Class B compliance, including oscillation-stoppage detection, independent watchdog timer (IWDTa) with configurable window function, CRC calculation unit, self-diagnostic A/D converter test mode, and register write protection. These capabilities reduce software verification burden and eliminate the need for external safety monitors in Class B appliance and industrial control applications.

What are the memory resources available on the R5F571MFCDFB#30?

The R5F571MFCDFB#30 includes 4 MB of on-chip code flash memory with background programming/erasing, 64 KB of reprogrammable data flash (100,000 cycles), 512 KB of general-purpose SRAM (with region-specific wait-state behavior), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. This memory hierarchy supports complex real-time OS, secure boot, and data logging without external memory.
