FAQ

What is the maximum operating frequency and real-time performance of the R5F571MFDDFC#V0?

The R5F571MFDDFC#V0 operates at a maximum system clock (ICLK) frequency of 240 MHz, delivering 480 DMIPS of processing performance. Its RXv2 core features a 5-stage pipeline, hardware FPU compliant with IEEE 754 single-precision, and low-latency interrupt response - enabling deterministic execution of 1-kHz motion control loops and real-time Ethernet packet processing without jitter.

Does the R5F571MFDDFC#V0 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F571MFDDFC#V0 integrates a dedicated PTP controller (EPTPCa) tightly coupled to both Ethernet MAC modules. It provides hardware timestamping of ingress/egress frames with nanosecond resolution, supports PTP slave/master/transparent clock modes, and synchronizes time across dual Ethernet ports - essential for time-sensitive networking in industrial PLCs and substation automation.

What safety features does the R5F571MFDDFC#V0 include for IEC60730 compliance?

The R5F571MFDDFC#V0 includes multiple hardware-based IEC60730 Class B support features: oscillation-stop detection for main/sub clocks, independent watchdog timer (IWDTa) with configurable window function, CRC calculation accelerator, A/D converter self-diagnostic mode, and register write protection for critical control registers - collectively reducing external safety component count and simplifying certification.

How many analog-to-digital converter channels does the R5F571MFDDFC#V0 provide, and what are their key capabilities?

The R5F571MFDDFC#V0 integrates two independent 12-bit S12ADC units: Unit 0 offers 8 channels with channel-dedicated sample-and-hold, and Unit 1 provides 21 channels - totaling 29 analog inputs. Both support 8/10/12-bit resolution, conversion times as fast as 0.42 µs (8-bit), scan/group modes, digital comparison, and self-diagnostic functions - ideal for multi-sensor industrial monitoring.

Is the R5F571MFDDFC#V0 pin-compatible with other RX71M group devices, and what package does it use?

Yes, the R5F571MFDDFC#V0 uses the PLQP0176KB-A package: a 176-pin LFBGA (24 mm × 24 mm, 0.5 mm pitch) shared across all 176/177-pin RX71M variants. This enables direct PCB footprint compatibility with R5F571MLDDFC#V0 (2 MB flash) and R5F571MHDDFC#V0 (3 MB flash), allowing scalable memory selection without layout revision.
