FAQ
What is the ASIL rating certified for the R7F7010293AFP-C#AA4?
The R7F7010293AFP-C#AA4 is certified to ISO 26262 ASIL-D for its CPU, memory subsystem, and safety mechanisms including lockstep monitoring, flash ECC, and voltage/temperature sensors. Renesas provides FMEDA reports, safety manuals, and diagnostic software libraries specifically validated for this part number. The R7F7010293AFP-C#AA4 achieves ≥99% single-point fault coverage and supports end-to-end safety analysis per ISO 26262 Part 5.
Does the R7F7010293AFP-C#AA4 support Ethernet Time-Sensitive Networking (TSN)?
The R7F7010293AFP-C#AA4 supports IEEE 802.1AS-2011 (gPTP) for precise time synchronization but does not implement full TSN features such as IEEE 802.1Qbv (time-aware shaper) or 802.1Qci (per-stream filtering). Its Ethernet AVB interface enables audio/video bridging and time-critical messaging with hardware timestamping accuracy of ±50 ns, sufficient for many automotive domain controller use cases but not for deterministic industrial TSN networks.
What cryptographic algorithms are accelerated by the ICUMD in the R7F7010293AFP-C#AA4?
The ICUMD in the R7F7010293AFP-C#AA4 accelerates AES-128/256 (ECB/CBC/GCM modes), SHA-256, RSA-2048, and ECDSA with NIST P-256 curves. It includes dedicated DMA for zero-copy data movement and secure key storage isolated by hardware fuses. The R7F7010293AFP-C#AA4 does not support post-quantum cryptography or SM2/SM3 algorithms.
Can the R7F7010293AFP-C#AA4 operate at maximum frequency across its full temperature range?
Yes-the R7F7010293AFP-C#AA4 operates at its rated 200 MHz CPU frequency across the full AEC-Q100 Grade 1 range (−40°C to +125°C ambient) when supplied with specified VDDP (1.14–1.26 V) and VDDA (4.5–5.5 V) rails. Internal PLL and voltage regulators maintain timing closure under thermal stress, and all timing parameters in the datasheet are guaranteed across temperature and voltage corners.
How many independent CAN FD interfaces does the R7F7010293AFP-C#AA4 provide?
The R7F7010293AFP-C#AA4 integrates five fully independent CAN FD controllers (CANFD0 through CANFD4), each supporting ISO 11898-1:2015, bit-rate switching up to 5 Mbps in the data phase, and time-triggered communication mode. Each controller has dedicated message RAM, filtering logic, and error counters-no shared resources between channels.
