Product details
Overview
R5F564MFDDFC#31 from Renesas is a 120-MHz 32-bit RXv2 MCU with single-precision FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), IEEE 1588-compliant dual Ethernet MAC, and full-speed USB 2.0 with battery charging - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F564MFDDFC#31 datasheet, R5F564MFDDFC#31 pinout, R5F564MFDDFC#31 application, or R5F564MFDDFC#31 equivalent, this page delivers verified package mapping (176-pin LFBGA, PLQP0176KB-A), confirmed peripheral channel counts (2× ETHERC, 1× USBA, 3× CAN), clock domain assignments (ICLK=120 MHz, PCLKA=120 MHz, PCLKB=60 MHz), and functional distinctions versus alternative RX64M variants.
Technical Context
The R5F564MFDDFC#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 240 DMIPS at 120 MHz. It integrates dual Ethernet controllers (ETHERC) each with dedicated EDMAC channels and IEEE 1588 PTP support via EPTPC, plus a dedicated USBA module with 8.5 KB transfer RAM and battery charging capability - all operating under independent clock domains (PCLKA for ETHERC/USBA/AES, PCLKB for timers/ADC).
Its memory subsystem includes 4 MB code flash (120 MHz, zero-wait), 64 KB data flash (100,000 write cycles), 512 KB SRAM (no wait), 32 KB ECC-protected RAM (SEC-DED), and 8 KB standby RAM. Peripheral control uses event linking (ELC) to interconnect 119 internal signals - enabling timer-triggered ADC conversions, PWM dead-time generation, and hardware-synchronized I/O without CPU intervention.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F564MFDDFC#31?
The R5F564MFDDFC#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance using the RXv2 CPU core. This metric is measured under standard conditions with cache enabled and reflects sustained integer instruction throughput - critical for real-time industrial protocol stacks running on the R5F564MFDDFC#31.
Does the R5F564MFDDFC#31 support IEEE 1588 Precision Time Protocol?
Yes, the R5F564MFDDFC#31 supports IEEE 1588 through its integrated EPTPC (PTP controller for Ethernet) block, which connects directly to both ETHERC channels. Hardware timestamping, sync/follow-up message handling, and best master clock selection are implemented in dedicated logic - enabling sub-microsecond clock synchronization essential for time-sensitive networking applications using the R5F564MFDDFC#31.
How many Ethernet MAC interfaces does the R5F564MFDDFC#31 include?
The R5F564MFDDFC#31 includes two fully independent IEEE 802.3-compliant Ethernet MAC interfaces (ETHERC), each with dedicated EDMAC channels and MII/RMII physical layer support. This dual-MAC capability allows the R5F564MFDDFC#31 to serve as a bridge between separate industrial networks without external switch ICs.
What USB capabilities does the R5F564MFDDFC#31 provide?
The R5F564MFDDFC#31 integrates a full-speed USB 2.0 host/function module with battery charging (USBA), supporting OTG operation and BC1.2-compliant charging detection. It includes 8.5 KB of on-chip RAM for endpoint buffering - eliminating external transceivers and simplifying USB connectivity in field-deployable devices using the R5F564MFDDFC#31.
Is the R5F564MFDDFC#31 pin-compatible with other RX64M group MCUs?
The R5F564MFDDFC#31 uses the 176-pin LFBGA package (PLQP0176KB-A) and shares pinout compatibility with other 176-pin RX64M variants such as R5F564MDDFC#31 and R5F564MEFFC#31. However, functional differences - including presence/absence of USBA, ETHERC count, and flash size - require firmware validation even when footprint matches, as the R5F564MFDDFC#31 enables dual Ethernet and USB battery charging not available on all variants.
