FAQ

What is the maximum operating frequency of the R5F572NNDGFP#30?

The R5F572NNDGFP#30 operates at a maximum CPU frequency of 240 MHz, achieved using an on-chip PLL with external crystal input (typically 12 MHz or 20 MHz). This frequency is sustained across the full industrial temperature range (−40°C to +85°C) with appropriate voltage regulation (VCC = 3.3 V ±10%). The R5F572NNDGFP#30 maintains instruction-level compatibility with lower-frequency RX72N variants, allowing scalable design reuse.

Does the R5F572NNDGFP#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NNDGFP#30 includes hardware-accelerated IEEE 1588 v2 timestamping within its Ethernet MAC, supporting both one-step and two-step clock synchronization modes. It provides sub-10 ns timestamp resolution on PTP event frames (Sync, Delay_Req, Pdelay_Req, Pdelay_Resp), enabling compliance with IEC 61850-9-3 and IEEE 802.1AS for time-sensitive networking. The R5F572NNDGFP#30 does not require external timestamping ICs.

What security features are implemented in hardware on the R5F572NNDGFP#30?

The R5F572NNDGFP#30 integrates dedicated hardware accelerators for AES-128/256 (ECB/CBC/CTR/GCM), SHA-1/224/256, RSA-2048, and a true random number generator (TRNG). These operate independently of the CPU, enabling concurrent cryptographic operations without performance penalty. The R5F572NNDGFP#30 also includes secure boot with ROM-based bootloader verifying ECDSA-P256 signatures, preventing unauthorized firmware execution.

Can the R5F572NNDGFP#30 be used in functional safety-certified systems?

Yes, the R5F572NNDGFP#30 supports IEC 61508 SIL2 certification through built-in diagnostic features: flash/SRAM BIST, lockstep CPU core option (available in pin-compatible variant R5F572NNDFP#30), and certified diagnostic software library. Renesas provides FMEDA reports and safety manuals. The R5F572NNDGFP#30 itself is rated for Standard quality grade but meets SIL2 requirements when used per safety manual guidelines.

What package type and pin count does the R5F572NNDGFP#30 use?

The R5F572NNDGFP#30 uses a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFQFP) package with 0.5 mm pitch, measuring 20 mm × 20 mm. This package is distinct from the LFBGA variants in the RX72N family and provides accessible pins for prototyping and rework. The R5F572NNDGFP#30 pinout includes dedicated Ethernet MII signals, dual CAN FD transceiver interfaces, and 12-bit ADC inputs routed to outer rows for noise isolation.
