FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJDGFC#V0?

The R5F571MJDGFC#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through its optimized RXv2 CPU core with 5-stage pipeline and single-cycle 32-bit multiply instruction. The R5F571MJDGFC#V0 maintains this performance across its full temperature range (–40°C to +105°C) with appropriate voltage and cooling design.

Does the R5F571MJDGFC#V0 support IEEE 1588 Precision Time Protocol hardware acceleration?

Yes, the R5F571MJDGFC#V0 includes a dedicated EPTPCa (PTP Controller for Ethernet) block compliant with IEEE 1588-2008. It provides hardware timestamping of Ethernet frames with sub-100 ns resolution, independent of CPU load. This enables precise time synchronization in industrial Ethernet applications such as motion control and distributed I/O without software timing overhead.

How many Ethernet MAC interfaces does the R5F571MJDGFC#V0 integrate, and what PHY support is included?

The R5F571MJDGFC#V0 integrates two independent IEEE 802.3-compliant Ethernet MAC controllers supporting 10/100 Mbps in full/half-duplex modes. It includes MII and RMII physical layer interfaces but does not integrate PHY transceivers - external PHY ICs must be used. The device also supports Wake-on-LAN and Magic Packet detection via the ETHERC module.

What are the flash and RAM capacities of the R5F571MJDGFC#V0, and how is memory protected?

The R5F571MJDGFC#V0 features 4 MB of on-chip code flash memory, 64 KB of reprogrammable data flash (100,000 erase cycles), 512 KB of general-purpose SRAM, 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. Memory protection is enforced via MPU (Memory Protection Unit), trusted memory blocks (code flash blocks 8–9), and register write-protection bits for critical control registers.

Is the R5F571MJDGFC#V0 qualified for functional safety standards like IEC 60730?

Yes, the R5F571MJDGFC#V0 includes hardware features explicitly designed for IEC 60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, independent watchdog timer (IWDTa) with window function, self-diagnostic A/D converter test, and register write protection. These capabilities enable certified safety firmware implementations without requiring external safety monitors.
