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

For engineers reviewing the R5F572NNHGFB#30 datasheet, R5F572NNHGFB#30 pinout, R5F572NNHGFB#30 application, or R5F572NNHGFB#30 equivalent, key selection criteria include Ethernet + IEEE 1588 timing accuracy, dual CAN FD bandwidth, flash/SRAM capacity for edge firmware, hardware crypto acceleration, and 224-pin LFBGA thermal performance in fanless industrial enclosures.

Technical Context

The R5F572NNHGFB#30 implements the RXv3 CPU core with 240 MHz max frequency, 10-stage superscalar pipeline, and FPU supporting single/double-precision IEEE 754 arithmetic. Its system architecture integrates a 64-bit AXI bus matrix, multi-layer AHB/APB bridges, and dedicated DMA channels for Ethernet, USB, and SDHI peripherals.

Real-time capability is enhanced by the on-chip timer units (GPT, CMT), interrupt controller with 256 priority levels, and MPU with 16 regions supporting memory protection across flash, SRAM, and peripheral address spaces - critical for IEC 61131-3 PLC runtime isolation and functional safety partitioning.

FAQ

What is the maximum operating frequency of the R5F572NNHGFB#30?

The R5F572NNHGFB#30 operates at a maximum CPU frequency of 240 MHz, achieved via its RXv3 superscalar core with 10-stage pipeline and on-chip PLL supporting multiple clock domains. This frequency enables sub-microsecond interrupt response and real-time execution of complex control algorithms within the R5F572NNHGFB#30's integrated peripherals.

Does the R5F572NNHGFB#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NNHGFB#30 includes dedicated IEEE 1588 v2 hardware timestamping logic in its Ethernet MAC, providing ±50 ns timestamp accuracy on transmit and receive paths. This capability is integral to the R5F572NNHGFB#30's role in time-sensitive networking applications such as synchronized motion control and distributed I/O systems.

What security features are implemented in hardware on the R5F572NNHGFB#30?

The R5F572NNHGFB#30 integrates hardware AES-128/256, SHA-256, RSA-2048 accelerators, a true random number generator (TRNG), and a secure boot ROM that validates ECDSA-signed firmware images. These features are physically isolated within the R5F572NNHGFB#30's security subsystem and enforce cryptographic operations without software exposure.

What package type and pin count does the R5F572NNHGFB#30 use?

The R5F572NNHGFB#30 is packaged in a 224-pin LFBGA (15 mm × 15 mm, 0.8 mm pitch) with an exposed thermal pad. This package is specified in the RX72N Group User's Manual: Hardware and supports industrial-grade thermal performance up to 105°C ambient, making it suitable for fanless enclosure deployment of the R5F572NNHGFB#30.

How much on-chip memory does the R5F572NNHGFB#30 provide?

The R5F572NNHGFB#30 integrates 4 MB of on-chip flash memory with ECC protection and 1 MB of SRAM with parity checking. This memory configuration supports large real-time OS images, protocol stacks (e.g., OPC UA, MQTT-SN), and local data buffering - all critical for autonomous operation of the R5F572NNHGFB#30 in disconnected edge environments.
