FAQ

What is the maximum operating temperature rating for the R7F7015823AFP-C#KA3?

The R7F7015823AFP-C#KA3 is qualified to AEC-Q100 Grade 1, supporting continuous operation from −40°C to +150°C ambient temperature. This rating is validated for under-hood automotive applications including engine control and transmission control modules where thermal stress is critical. The device's thermal design includes on-die temperature sensors and dynamic voltage/frequency scaling to maintain reliability within this range. All electrical specifications in the datasheet are guaranteed across this full temperature span.

Does the R7F7015823AFP-C#KA3 support ISO 26262 ASIL-D compliance out of the box?

The R7F7015823AFP-C#KA3 is ASIL-D ready with integrated hardware safety mechanisms including dual-core lockstep execution, Safety Support Unit (SSU), ECC on flash and SRAM, and memory BIST. However, full ISO 26262 ASIL-D compliance requires system-level implementation of safety software, diagnostic routines, and FMEDA analysis - all supported by Renesas' Functional Safety Package (FSP) and certified safety manuals. The R7F7015823AFP-C#KA3 provides the foundational hardware assurance needed to achieve ASIL-D in final ECU designs.

How many CAN FD interfaces does the R7F7015823AFP-C#KA3 include, and what are their data rate limits?

The R7F7015823AFP-C#KA3 integrates four independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps, with programmable bit timing registers per channel. The controller handles automatic protocol switching between classical CAN and FD frames, CRC calculation, and error confinement - enabling high-bandwidth sensor fusion and actuator coordination in modern vehicle networks without external protocol translators.

What package type and pin count does the R7F7015823AFP-C#KA3 use?

The R7F7015823AFP-C#KA3 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm pitch. It is moisture sensitivity level MSL3 and RoHS-compliant. This package supports full signal access to all integrated peripherals including CAN FD, Ethernet AVB, ADC, and GPTA timers. Pin-compatible variants exist within the RH850/F1K family, allowing scalable memory upgrades without PCB redesign - for example, the R7F7015833AFP-C#KA3 shares identical mechanical and thermal characteristics.

Is Ethernet AVB support in the R7F7015823AFP-C#KA3 hardware-accelerated, and which IEEE standards does it implement?

Yes, the R7F7015823AFP-C#KA3 includes a dedicated Ethernet AVB MAC with hardware acceleration for IEEE 802.1AS-2011 gPTP timestamping, IEEE 802.1Qav credit-based shaper, and IEEE 802.1Qat stream reservation. It supports 100BASE-T1 physical layer via external PHY and delivers deterministic latency under 100 μs for time-critical audio/video/data streams. The MAC offloads frame filtering, VLAN tagging, and checksum calculation from the CPU - enabling the R7F7015823AFP-C#KA3 to serve as a central domain controller without compromising real-time control performance.
