FAQ

What is the maximum operating frequency of the R7F7016904AFP-C#AA1?

The R7F7016904AFP-C#AA1 operates at a maximum CPU frequency of 300 MHz, achieved via its on-chip PLL using a 4–20 MHz external crystal or clock source. This frequency is sustained across the full –40°C to +125°C temperature range under specified voltage conditions, and all timing-critical peripherals-including CAN FD and Ethernet AVB-are synchronized to this clock domain. The R7F7016904AFP-C#AA1 maintains deterministic execution timing even under worst-case thermal and voltage conditions.

Does the R7F7016904AFP-C#AA1 support secure boot with hardware root-of-trust?

Yes, the R7F7016904AFP-C#AA1 includes a Hardware Security Module (HSM) that provides secure boot with immutable root-of-trust. It validates digital signatures of boot images using ECDSA-P256 or RSA-2048 before execution, stores cryptographic keys in tamper-resistant memory, and enforces secure debug lockdown. The R7F7016904AFP-C#AA1 also supports secure firmware updates with rollback protection and authenticated decryption using AES-256-GCM.

What safety certifications does the R7F7016904AFP-C#AA1 hold?

The R7F7016904AFP-C#AA1 is certified to ISO 26262 ASIL-D at the device level, with full documentation of FMEDA, FMEA, and safety analysis available from Renesas. It meets AEC-Q100 Grade 1 reliability requirements and includes integrated safety mechanisms-lockstep CPU, ECC on all memories, SMU-controlled BIST, and end-to-end data path checking-that collectively achieve >99% single-point fault coverage. The R7F7016904AFP-C#AA1 is qualified for use in powertrain and chassis safety applications without external safety monitors.

Can the R7F7016904AFP-C#AA1 interface directly with automotive Ethernet PHYs?
