FAQ

What is the maximum operating frequency of the R7F7016893AFP-C#KA1?

The R7F7016893AFP-C#KA1 operates at a maximum frequency of 160 MHz. This clock speed is achieved using the on-chip PLL with an external 8–20 MHz crystal input. The dual-core RH850 G3K architecture sustains deterministic real-time execution at this frequency, enabling tight control loop timing for engine and transmission applications. All timing specifications in the R7F7016893AFP-C#KA1 datasheet assume operation within the validated voltage and temperature ranges.

Does the R7F7016893AFP-C#KA1 support over-the-air (OTA) firmware updates?

Yes, the R7F7016893AFP-C#KA1 supports safe OTA firmware updates through its dual-bank flash architecture. One bank executes active code while the other receives and validates new firmware, allowing seamless switching without system interruption. This capability is integral to the R7F7016893AFP-C#KA1's design for modern automotive ECU software maintenance and cybersecurity patching, and requires no external memory or bootloader modifications.

What safety certifications apply to the R7F7016893AFP-C#KA1?

The R7F7016893AFP-C#KA1 is designed to support ISO 26262 ASIL-B compliance, with integrated hardware safety features including dual-core lockstep execution, Safety Monitor Unit (SMU), ECC-protected memories, and lockstep-aware interrupt controllers. It is also qualified to AEC-Q100 Grade 1 (−40°C to +125°C). Full ASIL-B certification requires system-level integration and verification - the R7F7016893AFP-C#KA1 provides the foundational hardware safety mechanisms needed for that process.

How many CAN FD interfaces does the R7F7016893AFP-C#KA1 include?

The R7F7016893AFP-C#KA1 includes two fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports data rates up to 5 Mbps in the data phase and maintains backward compatibility with classical CAN 2.0B. These interfaces are implemented in hardware with dedicated message RAM, filtering, and error counters - no CPU intervention is required for frame transmission or reception in the R7F7016893AFP-C#KA1.

Is the R7F7016893AFP-C#KA1 pin-compatible with other RH850/F1K variants?

Yes, the R7F7016893AFP-C#KA1 shares the same 176-pin LQFP package and pin assignment with other members of the RH850/F1K AFP-series, including the R7F7016883AFP-C#KA1 and R7F7016873AFP-C#KA1. Pin compatibility extends to power, ground, reset, clock, JTAG, CAN FD, LIN, SENT, and ADC signals. However, differences in flash size and peripheral enablement require corresponding software and configuration adjustments when migrating between variants.
