FAQ

What is the maximum operating frequency of the R7F7015803AFP-C#BA3?

The R7F7015803AFP-C#BA3 operates at a maximum CPU frequency of 160 MHz under specified voltage and temperature conditions. This clock speed applies to both lockstep cores simultaneously, with timing validated across the full -40°C to +125°C automotive temperature range and supported by on-chip PLL with spread-spectrum capability to reduce EMI.

Does the R7F7015803AFP-C#BA3 support ISO 26262 ASIL-D certification out of the box?

Yes, the R7F7015803AFP-C#BA3 includes hardware safety features required for ASIL-D decomposition, including dual-core lockstep, ECC on flash and RAM, safety management unit (SMU), and built-in self-test (BIST). However, full ASIL-D compliance requires proper configuration of these features in software and system-level integration per ISO 26262 Part 5 and Part 6 - the R7F7015803AFP-C#BA3 provides the certified hardware foundation.

How many CAN FD interfaces does the R7F7015803AFP-C#BA3 integrate?

The R7F7015803AFP-C#BA3 integrates four independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports programmable bit rates up to 5 Mbps in the data phase, automatic protocol switching between Classical CAN and CAN FD frames, and hardware timestamping with 1 ns resolution for precise event correlation.

What package type and pin count does the R7F7015803AFP-C#BA3 use?

The R7F7015803AFP-C#BA3 uses a 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with an exposed thermal pad. This package is pin-compatible with other RH850/F1K family members including R7F7015804AFP-C#BA3, enabling scalable design reuse across performance tiers within the same footprint.

Does the R7F7015803AFP-C#BA3 include integrated SENT receivers?

Yes, the R7F7015803AFP-C#BA3 includes four dedicated SENT (Single Edge Nibble Transmission) receivers compliant with SAE J2716 rev 3.0. These hardware decoders support variable frame lengths, CRC-4 checksum validation, and automatic nibble alignment - eliminating the need for software-based bit-banging or external SENT interface ICs in sensor-rich automotive applications.
