FAQ

What is the maximum operating frequency of the R7F7015834AFP-C#KA3?

The R7F7015834AFP-C#KA3 operates at a maximum core clock frequency of 200 MHz. This frequency is achieved using an on-chip PLL with programmable multiplication/division ratios and supports deterministic real-time execution for engine control and brake-by-wire applications. The R7F7015834AFP-C#KA3 maintains this speed across its full −40°C to +125°C operating range with voltage scaling managed internally.

Does the R7F7015834AFP-C#KA3 support AUTOSAR-compliant software stacks?

Yes, the R7F7015834AFP-C#KA3 is fully supported by Renesas' certified MCAL v4.3 drivers for AUTOSAR 4.3, covering CAN FD, LIN, FlexRay, ADC, DIO, GPT, and ICU. These drivers have been validated for ASIL-B compliance and integrate directly with leading AUTOSAR integrators like ETAS, Vector, and Elektrobit. The R7F7015834AFP-C#KA3 also includes hardware features such as memory protection and lockstep monitoring required for AUTOSAR OS safety partitions.

What safety certifications does the R7F7015834AFP-C#KA3 hold?

The R7F7015834AFP-C#KA3 is certified to ISO 26262 ASIL-B at the hardware level, with FMEDA reports and safety manuals available from Renesas. Its dual-core lockstep architecture, hardware safety monitor (SFM), ECC-protected memories, and lockstep-aware debug interface collectively enable ASIL-D decomposition in system-level designs. The R7F7015834AFP-C#KA3 is not certified for ASIL-D standalone operation but serves as a foundational element in ASIL-D architectures when combined with redundancy and external monitoring.

How many CAN FD interfaces does the R7F7015834AFP-C#KA3 include?

The R7F7015834AFP-C#KA3 integrates five independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting data rates up to 5 Mbps and frame payloads up to 64 bytes. All five controllers support time-triggered communication, flexible data-rate switching, and built-in message RAM with hardware acceptance filtering - eliminating the need for external CAN transceivers beyond physical layer components.

What package type and pin count does the R7F7015834AFP-C#KA3 use?

The R7F7015834AFP-C#KA3 uses a 516-pin FPBGA package (27 mm × 27 mm, 0.8 mm pitch) with an exposed thermal pad. This package is optimized for automotive under-hood thermal dissipation and supports high-speed signal integrity for CAN FD, FlexRay, and DDR-like memory buses. Pin assignments are documented in Renesas Hardware User's Manual Rev.1.30, Section 2A.2, and are identical across all RH850/F1KH-D8 variants including the R7F7015834AFP-C#KA3.
