FAQ

What is the maximum operating frequency of the R7F7010063AFP-C#AA4?

The R7F7010063AFP-C#AA4 operates at a maximum CPU frequency of 120 MHz. This clock speed is achieved via an internal PLL fed by an external 8–20 MHz crystal connected to the CLKIN pin. The device maintains timing integrity across its full −40°C to +105°C operating range, with guaranteed performance validated per AEC-Q100 Grade 2 requirements. All peripheral timing budgets-including ADC conversion, CAN FD bit timing, and GPTA PWM resolution-are derived from this 120 MHz base clock.

Does the R7F7010063AFP-C#AA4 support ISO 26262 functional safety certification?

Yes, the R7F7010063AFP-C#AA4 is designed to support ASIL-B compliance per ISO 26262. It includes dual-core lockstep CPU execution, Safety Support Core (SSC) with BIST and memory CRC, flash ECC with error correction, RAM parity protection, and clock/failure monitoring circuits. Renesas provides certified safety manuals, FMEDA reports, and diagnostic software libraries for R7F7010063AFP-C#AA4 to enable customer-level ASIL-B system certification-though final certification remains the responsibility of the end-system integrator.

What types of serial interfaces does the R7F7010063AFP-C#AA4 integrate?

The R7F7010063AFP-C#AA4 integrates four CAN FD controllers (supporting up to 5 Mbps data phase), one LINFlexD module compatible with LIN 2.2A and SAE J2602, and four SENT v3.0 receivers compliant with SAE J2716 Rev 3.0. It does not include SPI, I²C, or UART peripherals as standalone modules-those functions are implemented via GPIO-configurable serial communication units (SCUs) with software-driven protocols. CAN FD and SENT are hardware-accelerated for deterministic timing in safety-critical loops.

What is the flash memory size and endurance specification for the R7F7010063AFP-C#AA4?

The R7F7010063AFP-C#AA4 contains 1.5 MB of on-chip flash memory with ECC protection. Flash endurance is rated for 100,000 write/erase cycles per sector, and data retention is guaranteed for 20 years at 105°C or 40 years at 25°C. The memory supports read-while-write (RWW) operation, enabling background firmware updates without halting application execution-a critical feature for over-the-air (OTA) updates in deployed vehicles.

Is the R7F7010063AFP-C#AA4 pin-compatible with other RH850/F1KH variants?

Yes, the R7F7010063AFP-C#AA4 is pin-compatible with other 144-pin LQFP variants in the RH850/F1KH-D8 family, including R7F7010223AFP-C#AA4 and R7F7010083AFP-C#AA4. All share identical pin assignments, electrical characteristics, and thermal pad configuration. This allows direct substitution within the same footprint for memory-scaling or peripheral-option variations-provided the target application firmware accommodates the specific flash/RAM/peripheral configuration of the replacement part.
