Product details
Overview
R5F564MGHDFC#31 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 4 MB code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, CAN (3 channels), and 12-bit A/D (29 total channels). It targets industrial automation controllers requiring deterministic real-time I/O, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F564MGHDFC#31 datasheet, R5F564MGHDFC#31 pinout, R5F564MGHDFC#31 application, or R5F564MGHDFC#31 equivalent, key selection considerations include its 177-pin TFLGA package, dual Ethernet + USB + CAN coexistence, 120 MHz real-time performance with 240 DMIPS, and hardware-accelerated AES/SHA encryption for IEC 60730 Class B compliance.
Technical Context
The R5F564MGHDFC#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual Ethernet MACs with IEEE 1588 PTP support via EPTPC and dedicated EDMAC channels - one for each ETHERC channel plus a third for EPTPC timestamping.
Its memory subsystem includes 4 MB on-chip code flash (120 MHz, zero wait states), 64 KB data flash (100,000 write cycles), 512 KB SRAM (no wait states), and 32 KB ECC-protected RAM. Clocking supports external crystal (8–24 MHz) or internal HOCO/LOCO, with independent PCLKA (up to 120 MHz) and PCLKB (up to 60 MHz) domains for peripheral timing isolation.

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 |
|---|---|---|---|
| R5F565NEHDFC#31 | Same RX64M group, 177-pin TFLGA, but 2.5 MB flash, 384 KB SRAM, no USB battery charging support | Lacks USBA module; suitable where USB host functionality suffices without BC1.2 negotiation | Select when BOM cost reduction is prioritized over field-service USB charging capability |
| R5F566TEHDFC#31 | RX72M group successor: 240 MHz, 4 MB flash, 1 MB SRAM, enhanced EtherCAT slave support, no SDHI | Higher performance and EtherCAT focus; lacks SD host interface and battery charging USB | Choose for next-gen motion control systems requiring sub-100 ns EtherCAT cycle times and no local SD storage |

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F564MGHDFC#31?
The R5F564MGHDFC#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and optimized instruction set - enabling deterministic real-time response in industrial control loops where cycle time predictability is critical. The R5F564MGHDFC#31 sustains this performance across its full temperature range (–40°C to +105°C).
Does the R5F564MGHDFC#31 support IEEE 1588 Precision Time Protocol?
Yes, the R5F564MGHDFC#31 supports IEEE 1588 via its integrated EPTPC (PTP Controller for Ethernet) block, which is hardwired to both Ethernet MAC channels. It provides hardware timestamping of PTP event messages at the MAC layer with sub-100 ns resolution, enabling master and slave clock synchronization in industrial Ethernet networks without CPU overhead. The R5F564MGHDFC#31's dual Ethernet implementation allows concurrent PTP operation on separate network segments.
What are the flash and RAM capacities of the R5F564MGHDFC#31?
The R5F564MGHDFC#31 integrates 4 MB of on-chip code flash memory (zero wait states at 120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 512 KB of general-purpose SRAM (no wait states), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of standby RAM backed by VBATT. These memory resources are directly accessible by the RXv2 core and support background programming/erasing - essential for fail-safe firmware updates in the R5F564MGHDFC#31.
Which communication interfaces does the R5F564MGHDFC#31 include for industrial networking?
The R5F564MGHDFC#31 includes dual IEEE 1588-compliant Ethernet MACs, three CAN 2.0B modules (32 mailboxes each), nine SCI/SCIg channels, four SCIFA interfaces with 16-byte FIFOs, two I2C buses (up to 1 Mbps), QSPI, SD host interface, and full-speed USB 2.0 with battery charging. This combination enables simultaneous operation of EtherNet/IP, CANopen, Modbus TCP, and USB service ports - a capability confirmed in Renesas' RX64M reference designs for R5F564MGHDFC#31-based gateway platforms.
How does the R5F564MGHDFC#31 support IEC 60730 Class B functional safety compliance?
The R5F564MGHDFC#31 supports IEC 60730 Class B through hardware features including oscillation-stop detection, built-in CRC calculator, independent watchdog timer (IWDTa) with configurable window function, A/D converter self-diagnostic mode, register write protection bits, and memory protection unit (MPU). These are documented in the R01DS0173EJ0120 datasheet and validated in Renesas' Functional Safety Package for RX MCUs - enabling R5F564MGHDFC#31-based designs to achieve Class B certification without external safety monitors.
