Renesas R5F564MJCDFC#31

Overview

R5F564MJCDFC#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, full-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.

For engineers reviewing the R5F564MJCDFC#31 datasheet, R5F564MJCDFC#31 pinout, R5F564MJCDFC#31 application, or R5F564MJCDFC#31 equivalent, key selection criteria include its 177-pin TFLGA package, dual-channel Ethernet with PTP hardware timestamping, USBA module with 8.5 KB buffer, 12-bit dual A/D with self-diagnostic, and support for IEC60730 Class B compliance via CRC, oscillation-stop detection, and register write protection.

Technical Context

The R5F564MJCDFC#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACAa with 8 channels + EXDMACa with 2 channels) and a dedicated EDMACa (3-channel) for Ethernet offload - enabling concurrent frame processing without CPU intervention.

Clock domain separation enables simultaneous operation at full speed: ICLK up to 120 MHz for CPU/core logic, PCLKA up to 120 MHz for Ethernet/USB/AES, PCLKB up to 60 MHz for timers/ADC/DAC, and independent ADCLK domains (PCLKC/PCLKD) for dual 12-bit S12ADC units - ensuring precise analog sampling synchronization across mixed-signal subsystems.

FAQ

What is the maximum operating frequency and core architecture of the R5F564MJCDFC#31?

The R5F564MJCDFC#31 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 240 DMIPS and includes a single-precision IEEE-754 floating-point unit. This performance level enables real-time execution of complex control algorithms and protocol stacks without external co-processors - a key capability confirmed in the R01DS0173EJ0120 datasheet Rev.1.20.

Does the R5F564MJCDFC#31 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MJCDFC#31 integrates a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008, tightly coupled to its dual Ethernet MAC modules. Hardware timestamping occurs at the PHY interface boundary with sub-microsecond resolution, enabling accurate clock synchronization for time-sensitive networking in industrial automation. This feature is explicitly documented in Section 1.1 and Table 1.1 of the R01DS0173EJ0120 datasheet.

What package type and pin count does the R5F564MJCDFC#31 use?

The R5F564MJCDFC#31 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array measuring 8 mm × 8 mm with 0.5-mm pitch. This package supports all peripherals listed in the RX64M Group specification, including dual Ethernet, USBA, three CAN channels, and 127 general-purpose I/O pins. The package designation is confirmed in the "Package Information" section of the R01DS0173EJ0120 datasheet.

How does the R5F564MJCDFC#31 handle functional safety compliance for IEC60730?

The R5F564MJCDFC#31 includes multiple hardware features for IEC60730 Class B compliance: built-in CRC calculator, oscillation-stop detection circuit, self-diagnostic A/D converter, register write protection, and independent watchdog timer (IWDTa) with window function. These capabilities eliminate the need for external safety monitors in many applications and are validated in Renesas' Functional Safety Manual R01UH0425EJ0100. All are present and enabled in the R5F564MJCDFC#31 silicon.

What is the flash and RAM configuration of the R5F564MJCDFC#31?

The R5F564MJCDFC#31 integrates 4 MB of on-chip code flash memory (operating at 120 MHz with zero wait states), 64 KB of reprogrammable data flash (rated for 100,000 erase cycles), 512 KB of general-purpose SRAM (zero wait states), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. This memory hierarchy is specified in Table 1.1 of the R01DS0173EJ0120 datasheet and applies directly to the R5F564MJCDFC#31 variant.
