FAQ

What is the maximum operating frequency and DMIPS rating of the R5F564MLDDFP#31?

The R5F564MLDDFP#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and integrated single-precision IEEE-754 floating-point unit. The R5F564MLDDFP#31 sustains this performance with zero-wait-state access to 4 MB on-chip flash and 512 KB SRAM.

Does the R5F564MLDDFP#31 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MLDDFP#31 integrates two fully compliant IEEE 1588-2008 PTP controllers (EPTPC) linked to its dual Ethernet MACs (ETHERC). Each EPTPC provides hardware timestamping of ingress/egress frames with sub-microsecond resolution, enabling master/slave clock synchronization in industrial Ethernet applications like PROFINET IRT or TSN-aware systems. The R5F564MLDDFP#31 supports PTP profile configuration via dedicated registers and ELC-triggered timestamp capture.

What package type and pin count does the R5F564MLDDFP#31 use?

The R5F564MLDDFP#31 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. This LFBGA package supports 127 general-purpose I/O pins (including 19 with 5-V tolerance), dedicated Ethernet, USB, CAN, and high-speed analog interfaces. The R5F564MLDDFP#31's pinout is documented in Renesas datasheet R01DS0173EJ0120, pages 42–51.

How many Ethernet MAC interfaces does the R5F564MLDDFP#31 include?

The R5F564MLDDFP#31 includes two independent IEEE 802.3-compliant Ethernet MAC controllers (ETHERC), each supporting 10/100 Mbps operation in full- or half-duplex mode with MII or RMII physical layer interfaces. Both MACs integrate dedicated EDMAC DMA channels (3 total: 2 for ETHERC, 1 for EPTPC) and hardware-accelerated IEEE 1588 timestamping. This dual-MAC capability enables redundant network paths or protocol segregation-e.g., one for control traffic, one for diagnostics-in the R5F564MLDDFP#31.

What safety certifications or features does the R5F564MLDDFP#31 support for industrial applications?

The R5F564MLDDFP#31 includes hardware features aligned with IEC 60730 Class B requirements: oscillation-stop detection, built-in CRC calculator, independent watchdog timer (IWDTa) with window function, A/D converter self-diagnostic mode, and register write protection. It also supports Trusted Memory (blocks 8–9) to prevent unauthorized firmware extraction. These capabilities enable certified functional safety implementations without external monitors-the R5F564MLDDFP#31 is widely used in UL/EN 60730-certified industrial controllers.
