Renesas supplies safety manuals and FMEDA reports to assist customers in qualifying R7F7016923AFP-C#KA1 for specific automotive safety goals.
Does the R7F7016923AFP-C#KA1 support CAN FD with simultaneous classical CAN operation?
Yes, the R7F7016923AFP-C#KA1 supports concurrent operation of up to four CAN FD channels and maintains backward compatibility with classical CAN 2.0B. Each channel can be independently configured for FD mode (with flexible data rate up to 5 Mbps) or classical mode, enabling mixed-network gateways and phased vehicle architecture upgrades without hardware changes.
What is the maximum operating junction temperature for the R7F7016923AFP-C#KA1?
The R7F7016923AFP-C#KA1 has a maximum junction temperature of +150°C and is rated for ambient operation from −40°C to +125°C (AEC-Q100 Grade 1). Thermal design must ensure junction temperature remains within specification under worst-case power dissipation, especially during sustained 160 MHz CPU operation with multiple peripherals active.
How many SENT receiver channels does the R7F7016923AFP-C#KA1 integrate?
The R7F7016923AFP-C#KA1 integrates four independent SENT receiver channels (SENT0_IN0 through SENT0_IN3), each capable of decoding standard SENT frames with 12-bit resolution and hardware timestamping. These channels operate without CPU intervention, freeing the core for control tasks while maintaining precise sensor event timing.
Is the R7F7016923AFP-C#KA1 pin-compatible with other RH850/F1K variants?
Yes, the R7F7016923AFP-C#KA1 shares the same 176-pin LQFP package and pin assignment with other RH850/F1K members including R7F7016823AFP-C#KA1 and R7F7016933AFP-C#KA1.
