It targets industrial automation controllers requiring deterministic real-time networking, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MFGDFC#V1 datasheet, R5F564MFGDFC#V1 pinout, R5F564MFGDFC#V1 application, or R5F564MFGDFC#V1 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + PTP timing accuracy, on-chip 64 KB data flash with 100,000 write cycles, and support for IEC60730 Class B safety certification via built-in CRC, oscillation-stop detection, and A/D self-diagnostic functions.

Technical Context

The R5F564MFGDFC#V1 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual Ethernet MACs with dedicated EPTPC (IEEE 1588 PTP) and EDMAC controllers, supporting precise time synchronization in industrial Ethernet networks.

Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate independent clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/ADC. The device supports four low-power modes and battery-backed RTC operation via VBATT.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MFGDFC#V1?

The R5F564MFGDFC#V1 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 240 DMIPS and includes a single-precision IEEE-754 floating-point unit. This architecture enables deterministic real-time execution critical for industrial control loops and network timing in the R5F564MFGDFC#V1.

Does the R5F564MFGDFC#V1 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MFGDFC#V1 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPC) linked to both Ethernet MACs. It provides hardware timestamping with ±50 ns accuracy, sync message processing, and best master clock algorithm support. This implementation enables sub-microsecond time synchronization across distributed industrial nodes - a core capability of the R5F564MFGDFC#V1 for motion control and test equipment.

What are the flash memory capacities and endurance specifications for the R5F564MFGDFC#V1?

The R5F564MFGDFC#V1 includes 4 MB of on-chip code flash memory (no wait states at 120 MHz) and 64 KB of data flash memory rated for 100,000 program/erase cycles. Both support background operation (BGO), allowing concurrent execution and reprogramming. These specifications ensure robust firmware update resilience and long-term data logging integrity in the R5F564MFGDFC#V1's target applications.

How does the R5F564MFGDFC#V1 support functional safety standards like IEC60730?

The R5F564MFGDFC#V1 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, independent watchdog timer (IWDT) with windowing, A/D converter self-diagnostic, and register write protection. These capabilities are documented in Renesas' safety manual and enable certified runtime checks - a foundational safety architecture within the R5F564MFGDFC#V1 design.

What package type and pin count does the R5F564MFGDFC#V1 use, and what are its I/O characteristics?

The R5F564MFGDFC#V1 uses a 177-pin TFLGA package (8 mm × 8 mm, 0.5 mm pitch) with 127 general-purpose I/O pins. Of these, 19 pins are 5-V tolerant, all support pull-up resistors and open-drain outputs, and they operate across –40°C to +105°C (G-version). This compact, high-density package enables space-constrained industrial designs while maintaining signal integrity - a key physical attribute of the R5F564MFGDFC#V1.
