For engineers reviewing the R5F571MGGDFP#30 datasheet, R5F571MGGDFP#30 pinout, R5F571MGGDFP#30 application, or R5F571MGGDFP#30 equivalent, key selection criteria include dual Ethernet + PTP timestamping capability, 177-pin TFLGA package with 127 GPIOs, 240-MHz FPU-enabled real-time control, and IEC 60730 safety support for Class B compliance.

Technical Context

The R5F571MGGDFP#30 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and EPTPC hardware for IEEE 1588-2008 timestamping at sub-microsecond precision.

Its clock system combines external crystal (8–24 MHz), internal HOCO/LOCO oscillators, and PLL to generate ICLK up to 240 MHz while independently configuring PCLKA (120 MHz), PCLKB (60 MHz), and ADCLK (60 MHz) for peripheral domains - enabling simultaneous high-throughput data acquisition, network stack execution, and real-time motor control without resource contention.

FAQ

What is the maximum operating frequency and FPU capability of the R5F571MGGDFP#30?

The R5F571MGGDFP#30 operates at a maximum frequency of 240 MHz and includes a single-precision 32-bit IEEE-754 floating-point unit (FPU). This enables 480 DMIPS performance and supports computationally intensive tasks such as real-time FFT analysis, motor control algorithms, and cryptographic operations directly in hardware - eliminating reliance on software emulation and reducing cycle count for precision math in the R5F571MGGDFP#30.

Does the R5F571MGGDFP#30 support IEEE 1588 Precision Time Protocol (PTP) hardware timestamping?

Yes, the R5F571MGGDFP#30 integrates a dedicated PTP controller (EPTPCa) linked to its dual Ethernet MACs (ETHERC), providing hardware-accelerated timestamping compliant with IEEE 1588-2008. Timestamps are captured at the physical layer with sub-microsecond resolution, synchronized to internal MTU3 or GPT timers - ensuring deterministic time alignment for industrial automation, synchronized drive systems, and time-sensitive networking applications using the R5F571MGGDFP#30.

What package type and pin count does the R5F571MGGDFP#30 use?

The R5F571MGGDFP#30 uses the PTLG0177KA-A package: a 177-pin TFLGA (Thin Fine-Pitch Land Grid Array) measuring 8 mm × 8 mm with 0.5-mm pitch and 0.75-mm height. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, and integrates an exposed thermal pad for efficient heat dissipation - making it suitable for compact, thermally constrained industrial modules where the R5F571MGGDFP#30 is deployed.

How many Ethernet MAC interfaces does the R5F571MGGDFP#30 include, and what standards do they support?

The R5F571MGGDFP#30 includes two independent Ethernet MAC interfaces (ETHERC), each supporting IEEE 802.3 10/100 Mbps operation in full- and half-duplex modes, MII/RMII physical layer interfaces, Magic Packet™ wake-on-LAN, and IEEE 802.3x flow control. Both MACs are fully integrated with dedicated EDMAC channels and the EPTPCa PTP block - enabling redundant, time-synchronized networking essential for industrial control systems built around the R5F571MGGDFP#30.

Is the R5F571MGGDFP#30 qualified for functional safety standards like IEC 60730?

Yes, the R5F571MGGDFP#30 includes multiple hardware features certified for IEC 60730 Class B compliance, including oscillation-stoppage detection, hardware CRC calculation unit, independent watchdog timer (IWDTa) with window function, A/D converter self-diagnostic mode, and register write protection. These capabilities reduce external safety component requirements and accelerate functional safety certification for appliances, medical devices, and industrial controls using the R5F571MGGDFP#30.
