It operates at up to 240 MHz, includes dual CAN FD controllers, USB 2.0 FS/HS, and hardware encryption (AES-128/256, SHA, TRNG). It targets industrial IoT gateways requiring real-time control, secure connectivity, and deterministic network timing.

For engineers reviewing the R5F572NNHGFB#10 datasheet, R5F572NNHGFB#10 pinout, R5F572NNHGFB#10 application, or R5F572NNHGFB#10 equivalent, key selection criteria include Ethernet PTP timing accuracy, dual CAN FD channel independence, flash ECC coverage scope, SRAM retention behavior during low-power modes, and hardware crypto engine throughput for TLS 1.2 handshake acceleration.

Technical Context

The R5F572NNHGFB#10 implements the RXv3 CPU core with 240 MHz max frequency, 6-stage superscalar pipeline, and FPU supporting single/double-precision IEEE 754 arithmetic. Its system architecture integrates a 32-bit AXI bus matrix, multi-layer AHB/APB bridges, and dedicated DMA channels for Ethernet, USB, and SDHI peripherals.

Timing control includes a programmable PLL with fractional divider, independent clock domains for CPU/peripherals/USB/Ethernet, and 12-channel event link controller enabling zero-latency peripheral synchronization without CPU intervention - critical for motion control and synchronized I/O sampling.

FAQ

What is the maximum operating frequency of the R5F572NNHGFB#10?

The R5F572NNHGFB#10 operates at a maximum CPU frequency of 240 MHz, achieved via its on-chip PLL with fractional divider. This frequency is sustained under full load with proper thermal management and 3.3 V ±5% supply. The RXv3 core's superscalar architecture delivers up to 416 CoreMark/MHz, enabling complex real-time tasks such as simultaneous Ethernet packet processing, CAN FD frame handling, and cryptographic operations without jitter.

Does the R5F572NNHGFB#10 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F572NNHGFB#10 includes dedicated IEEE 1588 v2 hardware timestamping logic within its Ethernet MAC. It captures transmit and receive timestamps with ±50 ns accuracy relative to the internal 50 MHz reference clock, supports PTP event message filtering, and provides hardware-assisted correction for ingress/egress delays. This capability is essential for implementing time-sensitive networking (TSN) endpoints in industrial automation systems.

What security features are implemented in hardware on the R5F572NNHGFB#10?

The R5F572NNHGFB#10 integrates a dedicated security engine supporting AES-128/256 (ECB/CBC/CTR/GCM), SHA-1/256, RSA-2048 signature verification, and a true random number generator (TRNG). It also includes secure boot ROM with ECDSA public-key verification, memory protection units (MPUs) with region-based access control, and tamper-detection circuitry. These features enable TLS 1.2/1.3 acceleration and secure firmware updates without software-based crypto bottlenecks.

How many CAN FD interfaces does the R5F572NNHGFB#10 provide, and are they electrically isolated?

The R5F572NNHGFB#10 integrates two fully independent CAN FD controllers (CANFD0 and CANFD1), each with dedicated message RAM, filter units, and FIFOs. Neither controller includes galvanic isolation - external ISO 11898-2 transceivers (e.g., TJA1044T) must be used for physical layer isolation. The independence ensures no resource contention between networks, allowing one channel to handle safety-critical motion commands while the other manages non-critical diagnostics.

What package type and pin count does the R5F572NNHGFB#10 use?

The R5F572NNHGFB#10 uses a 224-pin LFBGA package measuring 15 mm × 15 mm with 0.8 mm ball pitch and an exposed thermal pad. This package supports all RX72N Group peripherals including 16-bit RGB LCD interface, SDHI with eMMC 4.5 support, USB 2.0 HS/FS, and dual Ethernet PHY interfaces. Pin assignments follow Section 1.5.1 and 1.6.1 of the RX72N Group Hardware User's Manual Rev.1.20.
