FAQ
What is the maximum operating temperature rating for the R7F7016203AFP-C#KA3?
The R7F7016203AFP-C#KA3 is rated for operation from −40°C to +125°C ambient temperature and is qualified per AEC-Q100 Grade 1. This rating enables deployment in under-hood environments such as front-radar modules and engine control units where thermal stress is critical. The 176-pin LQFP package includes an exposed thermal pad to maintain junction temperature within safe limits at full 400 MHz operation.
Does the R7F7016203AFP-C#KA3 support ISO 26262 ASIL-D compliance out of the box?
Yes, the R7F7016203AFP-C#KA3 supports ISO 26262 ASIL-D compliance through its dual-core RH850 G3KH lockstep architecture, hardware memory protection unit (MPU), flash ECC with background scrubbing, and built-in self-test (BIST) for CPU and memory subsystems. Renesas provides certified safety manuals, FMEDA reports, and diagnostic software libraries specifically for the R7F7016203AFP-C#KA3 to accelerate ASIL-D certification.
How many CAN FD interfaces does the R7F7016203AFP-C#KA3 integrate, and what is their maximum bit rate?
The R7F7016203AFP-C#KA3 integrates five independent CAN FD controllers, each supporting up to 5 Mbps data phase bit rate and 1 Mbps arbitration phase. All five channels support time-triggered communication (TTCAN) mode and have dedicated message RAM with hardware acceptance filtering - eliminating CPU polling overhead and enabling deterministic scheduling in safety-critical ADAS networks.
What cryptographic algorithms are accelerated by the hardware security module (HSM) in the R7F7016203AFP-C#KA3?
The HSM in the R7F7016203AFP-C#KA3 accelerates AES-128/256 (ECB/CBC/CTR/GCM modes), SHA-256, RSA-2048, and ECC P-256 operations with zero CPU intervention. These accelerators enable secure boot validation, encrypted firmware storage, and real-time signed CAN FD message generation - all while maintaining full 400 MHz CPU performance for application code execution.
Is the R7F7016203AFP-C#KA3 pin-compatible with other members of the RH850/F1K family?
No, the R7F7016203AFP-C#KA3 is not pin-compatible with other RH850/F1K variants due to its unique 176-pin LQFP package and specific peripheral allocation (e.g., integrated Ethernet AVB MAC pins). While it shares the same RH850 G3KH core and memory architecture with other F1K devices, pin mapping differs significantly - requiring dedicated PCB layout for the R7F7016203AFP-C#KA3. Renesas provides migration guides but no drop-in replacements.
