Product details
Overview
R5F564MFGDFB#31 from Renesas is a 120-MHz 32-bit RXv2 core MCU with single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), and integrated IEEE 1588-compliant Ethernet MAC - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and dual-network redundancy.
For engineers reviewing the R5F564MFGDFB#31 datasheet, R5F564MFGDFB#31 pinout, R5F564MFGDFB#31 application, or R5F564MFGDFB#31 equivalent, key selection criteria include its 177-pin TFLGA package, 120 MHz operation with 240 DMIPS, dual CAN modules, USB 2.0 FS with battery charging support, and hardware AES/SHA encryption for IEC 60730 Class B compliance.
Technical Context
The R5F564MFGDFB#31 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling deterministic interrupt latency and secure partitioning of firmware and data. Its clock system supports independent domain clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers and ADCs.
It integrates three distinct DMA subsystems: 8-channel DMAC for general-purpose transfers, 2-channel EXDMAC for high-priority event-triggered transfers, and 3-channel EDMAC dedicated to Ethernet frame handling - offloading CPU bandwidth while maintaining strict timing for time-sensitive protocols like IEEE 1588 PTP.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F565NEDDFB#30 | Same RX65N Group, 120 MHz, but 2 MB flash, no USBA module, only one Ethernet MAC. | Lacks battery-charging USB and second Ethernet port - unsuitable for dual-network gateway or field-service charging use cases. | Select when cost-sensitive designs require only single Ethernet and omit USB charging functionality. |
| STM32H743ZIT6 | ARM Cortex-M7, 480 MHz, 2 MB flash, no native IEEE 1588, requires external PHY for 1588 timestamping. | No integrated PTP hardware - adds 2–3 µs timestamp uncertainty and external component cost vs. R5F564MFGDFB#31's EPTPC. | Choose for high-throughput DSP workloads where FPU throughput outweighs deterministic PTP needs. |
Compared with R5F564MFGDFB#31, the R5F565NEDDFB#30 reduces flash and Ethernet capability for lower BOM cost, while the STM32H743ZIT6 trades integrated PTP and USB charging for higher raw CPU performance - making R5F564MFGDFB#31 optimal for time-critical, dual-interface industrial edge nodes.
