Overview
R5F564MFDDFP#31 from Renesas is a 32-bit RXv2 microcontroller targeting industrial Ethernet and USB-connected embedded systems, featuring 120 MHz operation (240 DMIPS), 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging support, and integrated 12-bit A/D and D/A converters.
For engineers reviewing the R5F564MFDDFP#31 datasheet, R5F564MFDDFP#31 pinout, R5F564MFDDFP#31 application, or R5F564MFDDFP#31 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel Ethernet with PTP hardware acceleration, USBA module with 8.5 KB buffer, and support for IEC60730 functional safety compliance via built-in CRC, IWDTa, and self-diagnostic A/D features.
Technical Context
The R5F564MFDDFP#31 implements the RXv2 CPU core with single-precision IEEE-754 FPU, two multiply-accumulate units, and memory protection unit (MPU). It operates at up to 120 MHz with no-wait 4 MB flash and 512 KB SRAM, while supporting little- or big-endian data arrangement and variable-length instructions for compact code density.
Clock architecture includes independent PLL, HOCO/LOCO oscillators, and configurable peripheral clock domains (PCLKA up to 120 MHz for ETHERC/USBA/AES; PCLKB up to 60 MHz for timers and A/D). Power management provides four low-power modes and RTC battery backup via VBATT, with voltage monitoring across three LVD circuits.

FAQ
What is the maximum operating frequency and performance rating of the R5F564MFDDFP#31?
The R5F564MFDDFP#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS of processing performance. Its RXv2 CPU core includes a single-precision IEEE-754 floating-point unit, two multiply-accumulate units, and a 5-stage pipeline. This performance level enables real-time protocol stack execution-including TCP/IP, USB device/host, and CAN FD-without external co-processors. The R5F564MFDDFP#31 sustains this speed with zero-wait-state access to both 4 MB flash and 512 KB SRAM.
Does the R5F564MFDDFP#31 support IEEE 1588 Precision Time Protocol (PTP) hardware timestamping?
Yes, the R5F564MFDDFP#31 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPC) linked directly to its dual Ethernet MAC (ETHERC). This hardware block captures transmit and receive timestamps with sub-microsecond resolution, independent of CPU load. It supports PTPv2 (IEEE 1588-2008) profiles including boundary clocks and transparent clocks, enabling synchronization accuracy compliant with IEC 61850-9-3 Class C in industrial Ethernet deployments. The R5F564MFDDFP#31 does not require external timestamping ICs.
What USB capabilities does the R5F564MFDDFP#31 provide, and does it support battery charging?
The R5F564MFDDFP#31 includes the USBA module-a full-speed USB 2.0 host/function controller with integrated transceiver and 8.5 KB on-chip RAM buffer. It supports OTG operation and battery charging per USB Battery Charging Specification Rev 1.2 (BC1.2), including DCP, CDP, and SDP detection. Unlike basic USB modules, USBA enables direct negotiation of charging current (up to 1.5 A) without external charger ICs. This functionality is exclusive to 176- and 177-pin RX64M variants-confirming R5F564MFDDFP#31's full support.
How does the R5F564MFDDFP#31 meet IEC 60730 Class B functional safety requirements?
The R5F564MFDDFP#31 includes multiple hardware features certified for IEC 60730 Class B compliance: oscillation-stoppage detection, hardware CRC calculator, independent watchdog timer (IWDTa) with window function, register write protection, and self-diagnostic A/D converter. These eliminate reliance on software-only checks. The A/D self-test generates internal reference voltages (VREFL0/VREFH0) to verify linearity and offset-critical for safety-critical sensor monitoring. All features are documented in Renesas' Functional Safety Manual R01UM0077EJ0200 for the RX64M Group, confirming R5F564MFDDFP#31's suitability for household appliance and industrial control applications.
What are the memory resources available on the R5F564MFDDFP#31, and how are they protected?
The R5F564MFDDFP#31 provides 4 MB of on-chip code flash with background programming/erasing (BGO), 64 KB of reprogrammable data flash (100,000 erase/write cycles), 512 KB of general SRAM (no wait states), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of standby RAM. Flash protection includes Trusted Memory (TM) blocks 8–9, preventing unauthorized read-out. SRAM ECC detects and corrects single-bit errors and detects double-bit errors. The R5F564MFDDFP#31 also supports memory protection unit (MPU) configuration to isolate privileged vs. user code and data spaces-enabling robust partitioning in RTOS environments.
