Does the R7F7016473AFP-C#AA1 support CAN FD communication?

Yes, the R7F7016473AFP-C#AA1 integrates four independent CAN FD controllers compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps in FD mode and classic CAN up to 1 Mbps. Each controller features message RAM with hardware acceptance filtering, time-triggered transmission scheduling, and error counters accessible via dedicated registers - enabling robust communication in R7F7016473AFP-C#AA1-based ECU designs.

What is the maximum operating frequency of the R7F7016473AFP-C#AA1?

The R7F7016473AFP-C#AA1 operates at a maximum system clock frequency of 160 MHz, achieved via an on-chip PLL with programmable multiplication factor and spread-spectrum modulation to reduce EMI. The PLL accepts 4–20 MHz crystal inputs and maintains ±0.5% accuracy across the full automotive temperature range (-40°C to +125°C), ensuring deterministic timing for R7F7016473AFP-C#AA1 real-time control loops.

How is memory protected against corruption in the R7F7016473AFP-C#AA1?

The R7F7016473AFP-C#AA1 provides hardware-level memory protection through 64-bit ECC on 4 MB on-chip flash and SEC-DED ECC on 512 KB SRAM, with automatic error correction and interrupt generation on uncorrectable errors. Flash memory includes background read capability during programming and lock bits for region protection - critical for maintaining integrity of R7F7016473AFP-C#AA1 firmware in harsh automotive environments.

What package type and thermal characteristics does the R7F7016473AFP-C#AA1 use?
