Product details
Overview
R5F564MGGDFB#31 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 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 - deployed in industrial automation gateways requiring real-time control, secure connectivity, and deterministic timing.
For engineers reviewing the R5F564MGGDFB#31 datasheet, R5F564MGGDFB#31 pinout, R5F564MGGDFB#31 application, or R5F564MGGDFB#31 equivalent, key selection criteria include its 177-pin TFLGA package, dual-channel Ethernet with PTP, USB 2.0 FS host/function + battery charging capability, 120 MHz real-time performance with FPU, and IEC60730 safety features for certified embedded control systems.
Technical Context
The R5F564MGGDFB#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPC and dedicated EDMAC channels - one channel assigned to ETHERC and another to EPTPC - enabling hardware-accelerated timestamping and cut-through frame forwarding between ports.
Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis to drive ICLK at 120 MHz while independently configuring PCLKA (up to 120 MHz for high-speed peripherals), PCLKB (up to 60 MHz for timers and ADC), and ADCLK (up to 60 MHz per S12AD unit). The device supports four low-power modes and includes an independent watchdog timer (IWDTa) with window function and dedicated 120-kHz oscillator.

FAQ
What is the maximum operating frequency and CPU architecture of the R5F564MGGDFB#31?
The R5F564MGGDFB#31 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU), on-chip multiplier (1-cycle execution), and divider (2-cycle execution). This architecture enables deterministic real-time response in industrial control applications where the R5F564MGGDFB#31 serves as the primary system controller.
Does the R5F564MGGDFB#31 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F564MGGDFB#31 supports IEEE 1588 through its integrated PTP controller for Ethernet (EPTPC), which is hardware-connected to both Ethernet MAC modules. Timestamping occurs at the physical layer with hardware capture of transmit/receive packet timestamps, enabling sub-microsecond synchronization accuracy. The R5F564MGGDFB#31 uses dedicated EDMAC channels - one for ETHERC and one for EPTPC - to offload timestamp processing from the CPU, making it suitable for time-critical industrial Ethernet applications.
What USB capabilities does the R5F564MGGDFB#31 provide, and is battery charging supported?
The R5F564MGGDFB#31 includes the USBA module, a full-speed USB 2.0 host/function controller with integrated battery charging (BC1.2) detection logic - available only on 176- and 177-pin packages like this part. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps, host only) transfers, OTG operation, and incorporates 8.5 KB of on-chip RAM for endpoint buffering. No external pull-up/pull-down resistors are required. This makes the R5F564MGGDFB#31 ideal for field-serviceable gateways that accept firmware updates from USB power banks.
How many Ethernet MAC interfaces does the R5F564MGGDFB#31 integrate, and what PHY interfaces are supported?
The R5F564MGGDFB#31 integrates two independent IEEE 802.3-compliant Ethernet MAC controllers (ETHERC), each supporting 10/100 Mbps operation in full- or half-duplex mode. It supports both MII (Media Independent Interface) and RMII (Reduced MII) PHY connections, enabling flexible PHY selection. Each MAC has dedicated EDMAC channels and supports Magic Packet™ wake-on-LAN, IEEE 802.3x flow control, and multicast filtering - essential features for redundant industrial network topologies used by the R5F564MGGDFB#31.
What safety and reliability features make the R5F564MGGDFB#31 suitable for IEC60730-certified applications?
The R5F564MGGDFB#31 includes multiple IEC60730-compliant features: oscillation-stoppage detection, hardware CRC calculator, self-diagnostic A/D converter, register write protection, independent watchdog timer (IWDTa) with configurable window function, and memory protection unit (MPU). These features allow developers to meet Class B requirements without external safety monitors. The R5F564MGGDFB#31's design enables systematic fault coverage exceeding 90% - a key requirement for certified industrial control systems.
