Product details
Overview
R5F564MJGDFB#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 networking gateways requiring deterministic real-time control, secure connectivity, and high-precision analog sensing.
For engineers reviewing the R5F564MJGDFB#31 datasheet, R5F564MJGDFB#31 pinout, R5F564MJGDFB#31 application, or R5F564MJGDFB#31 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB + CAN coexistence, 120 MHz real-time performance with 240 DMIPS, and IEC60730-ready safety features including CRC, oscillation-stop detection, and self-diagnostic A/D.
Technical Context
The R5F564MJGDFB#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual independent Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPC and dedicated EDMAC channels - one for each ETHERC channel plus one for EPTPC - enabling hardware-accelerated time-synchronized packet handling without CPU intervention.
Its clock system combines external crystal (8–24 MHz) with internal PLL and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated), allowing independent domain clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, PCLKB up to 60 MHz for timers and A/D, and PCLKC/PCLKD at 60 MHz for dual S12AD units - ensuring precise timing isolation across mixed-criticality peripherals.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F564MJGDFB#31?
The R5F564MJGDFB#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS of processing performance. This is achieved through its RXv2 CPU core with 5-stage pipeline and optimized instruction set. The R5F564MJGDFB#31 maintains this performance across its full operating temperature range (–40°C to +105°C) with no wait states on its 4 MB code flash memory, making it suitable for hard real-time industrial control tasks.
Does the R5F564MJGDFB#31 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F564MJGDFB#31 includes full hardware support for IEEE 1588-2008 via its integrated EPTPC (PTP Controller for Ethernet) block, which connects directly to both Ethernet MAC channels. It provides hardware timestamping on transmit/receive packets, PTP message parsing, and clock synchronization logic - eliminating software overhead and enabling sub-microsecond time accuracy. The R5F564MJGDFB#31 uses this capability to serve as a boundary clock or transparent clock in industrial time-sensitive networks.
What are the analog capabilities of the R5F564MJGDFB#31, particularly regarding A/D and D/A converters?
The R5F564MJGDFB#31 integrates two independent 12-bit A/D converters: S12AD unit 0 (8 channels) and unit 1 (21 channels), supporting 8/10/12-bit resolution with conversion times as fast as 0.42 µs. It also includes two 12-bit D/A channels with selectable amplifier or direct output. Both A/D units feature self-diagnostic functions, analog input disconnection detection, and hardware-triggered sampling via MTU3/GPT/TPU timers - all essential for certified industrial measurement systems using the R5F564MJGDFB#31.
How does the R5F564MJGDFB#31 support functional safety standards like IEC60730?
The R5F564MJGDFB#31 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection, CRC calculation unit, self-diagnostic A/D converter, register write protection, independent watchdog timer (IWDT) with window function, and memory protection unit (MPU). These allow developers to implement safety mechanisms without external components. The R5F564MJGDFB#31 datasheet documents these features explicitly for Class B qualification, and Renesas provides safety manuals and diagnostic software libraries specifically for this device.
What package type and pin count does the R5F564MJGDFB#31 use, and what are its thermal characteristics?
The R5F564MJGDFB#31 uses a 177-pin TFLGA package (PTLG0177KA-A), measuring 8 mm × 8 mm with 0.5 mm pitch and an exposed thermal pad. It is rated for industrial temperature range (–40°C to +105°C) and operates from a single 2.7–3.6 V supply. Its low-power design draws only 0.3 mA/MHz typical in active mode, and it supports four low-power modes including deep software standby with 8 KB backup RAM - making the R5F564MJGDFB#31 suitable for fanless, sealed industrial enclosures.
