FAQ

What is the maximum operating frequency of the R5F572NNDGFC#V0?

The R5F572NNDGFC#V0 operates at a maximum frequency of 240 MHz. This clock speed is achieved using the on-chip PLL with external crystal input (typically 20 MHz), and it enables 416.7 DMIPS performance. The R5F572NNDGFC#V0 maintains this frequency across its full industrial temperature range (−40°C to +85°C) when supplied with regulated 3.3 V and proper thermal management.

Does the R5F572NNDGFC#V0 include an integrated Ethernet PHY?

No, the R5F572NNDGFC#V0 integrates only the Ethernet MAC layer compliant with IEEE 802.3 10/100BASE-TX. An external PHY chip (e.g., DP83848 or LAN8720) is required for physical layer signaling. The R5F572NNDGFC#V0 provides MII/RMII interface signals, IEEE 1588 timestamping registers, and MDIO management bus to interface directly with standard PHYs.

What security features are implemented in hardware on the R5F572NNDGFC#V0?

The R5F572NNDGFC#V0 includes hardware AES-128/256, SHA-1/224/256, TRNG, and a secure boot ROM that verifies ECDSA-P256 signatures of firmware images. These features are accessible via the Renesas Secure IP (RSIP-E) module and enable TLS 1.2/1.3 acceleration, secure firmware updates, and cryptographic key protection without software-based vulnerabilities.

How many CAN FD interfaces does the R5F572NNDGFC#V0 support?

The R5F572NNDGFC#V0 supports two independent CAN FD controllers compliant with ISO 11898-1:2015. Each controller has dedicated message RAM, filtering logic, and DMA channels - allowing simultaneous operation on separate buses at data rates up to 5 Mbps and payloads up to 64 bytes. Both controllers support loopback self-test and bit-rate switching.

What package type and pin count does the R5F572NNDGFC#V0 use?

The R5F572NNDGFC#V0 uses a 224-pin LFBGA package measuring 15 mm × 15 mm with 0.8 mm ball pitch. This package includes 16 dedicated power/ground pairs, four VCCIO banks for mixed-voltage I/O, and optimized signal routing for high-speed interfaces including Ethernet, USB, and CAN FD.
