FAQ
What is the maximum junction temperature rating for the R7F7016904AFP-C#KA1?
The R7F7016904AFP-C#KA1 is rated for operation up to +150°C junction temperature, consistent with its AEC-Q100 Grade 1 qualification (−40°C to +125°C ambient). This thermal margin enables reliable deployment in high-power-density engine control modules where PCB-level heat dissipation is constrained. Thermal design must maintain TJ ≤ 150°C under worst-case load conditions per Renesas' thermal resistance specifications in the datasheet.
Does the R7F7016904AFP-C#KA1 support JTAG debugging in lockstep mode?
Yes, the R7F7016904AFP-C#KA1 supports full JTAG debugging via the dedicated JTAG port (TCK/TMS/TDI/TDO pins), including visibility into both lockstep cores simultaneously. Debug access remains enabled during lockstep operation, allowing real-time register inspection and breakpoint setting without disabling safety monitoring. However, debug entry triggers a controlled safety state transition per ISO 26262 requirements.
How many CAN FD channels does the R7F7016904AFP-C#KA1 integrate, and what is their maximum bit rate?
The R7F7016904AFP-C#KA1 integrates five fully independent CAN FD controllers, each supporting bit rates up to 5 Mbps in FD mode and 1 Mbps in classical CAN mode. All channels feature hardware message filtering, transmit/receive FIFOs, and built-in loopback testing-enabling concurrent high-speed communication with powertrain, chassis, and body domain ECUs without software arbitration overhead.
Is the R7F7016904AFP-C#KA1 pin-compatible with other RH850/F1KH-D8 variants?
Yes, the R7F7016904AFP-C#KA1 shares identical 176-pin LQFP mechanical and electrical pinout with all RH850/F1KH-D8 family members, including R7F7016894AFP-C#KA1 and R7F7016914AFP-C#KA1. Pin assignments for power, reset, clocks, and peripheral I/O are fixed across the family, enabling hardware reuse across memory- and feature-scaled variants without PCB redesign.
What safety documentation is provided by Renesas for the R7F7016904AFP-C#KA1?
Renesas provides comprehensive ISO 26262-compliant safety documentation for the R7F7016904AFP-C#KA1, including the Safety Manual, FMEDA report (FIT rate, diagnostic coverage), safety analysis summary, and hardware/software interface specification (HSIS).
