Technical Context

The R5F572NNHGFC#V0 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 64-bit AXI bus matrix, dual-channel 16-bit ADC (1 Msps total), and programmable gain amplifier (PGA) with 12-bit resolution.

Peripherals include two independent CAN FD controllers compliant with ISO 11898-1:2015, an Ethernet controller supporting MII/RMII interfaces and hardware timestamping with ±50 ns precision, and a dedicated security engine enabling secure boot via ROM-based bootloader with SHA-256 signature verification.

FAQ

What is the maximum operating frequency of the R5F572NNHGFC#V0?

The R5F572NNHGFC#V0 operates at a maximum CPU frequency of 240 MHz, achieved using the on-chip PLL with external crystal input (typically 12 MHz or 20 MHz). This frequency is fully supported across the full industrial temperature range (−40°C to +105°C) and enables sub-microsecond interrupt response times critical for motion control loops. The R5F572NNHGFC#V0 maintains this performance without throttling under sustained thermal load when mounted on a 4-layer PCB with proper thermal vias.

Does the R5F572NNHGFC#V0 include an integrated Ethernet PHY?

No, the R5F572NNHGFC#V0 integrates only the Ethernet MAC layer compliant with IEEE 802.3 and supports MII/RMII interfaces. An external PHY IC (e.g., DP83848 or LAN8742A) is required for physical layer signaling. The R5F572NNHGFC#V0 provides all necessary clock outputs (REF_CLK, TX_CLK), control signals (TX_EN, RX_DV), and hardware timestamping registers to interface directly with standard 10/100 Mbps PHYs without glue logic.

What security features are implemented in hardware on the R5F572NNHGFC#V0?

The R5F572NNHGFC#V0 includes a dedicated security engine with hardware accelerators for AES-128/256 (ECB/CBC/CTR modes), SHA-256, and RSA-2048. It also features a ROM-based secure bootloader that validates firmware signatures using SHA-256 before execution. These capabilities are documented in the RX72N Group User's Manual: Hardware (Section 42) and enable IEC 62443-3-3 compliance for secure firmware updates. The R5F572NNHGFC#V0 does not include TRNG or secure key storage beyond fuse-based provisioning.

Is the R5F572NNHGFC#V0 pin-compatible with other RX72N Group devices?

Yes, the R5F572NNHGFC#V0 in the 176-pin LFBGA package shares identical pinout with other RX72N Group members in the same package variant (e.g., R5F572MNHGFC#V0, R5F572NNHGBD#V0), including power, reset, clock, JTAG, Ethernet, CAN FD, and ADC signal assignments. This allows drop-in replacement for memory-scaling or feature-tiering within the same PCB layout. However, pin compatibility does not extend to different packages (e.g., 144-pin LFQFP) or unrelated RX families like RX671.

What development tools are officially supported for the R5F572NNHGFC#V0?

Renesas provides full toolchain support for the R5F572NNHGFC#V0, including e2 studio IDE, CS+ compiler, and the RX72N Envision Kit (RTK772200C00000BJ) evaluation board. Debugging is enabled via JTAG/SWD using E2 Lite or E2 emulator. Peripheral configuration is assisted by the Smart Configurator plug-in, which auto-generates initialization code for Ethernet, CAN FD, and ADC modules. All tools are validated against the R5F572NNHGFC#V0 silicon revision specified in the RX72N Group Datasheet (R01DS0343EJ).
