FAQ
What safety certifications does the R7F7010223AFE#BA4 support?
The R7F7010223AFE#BA4 is designed to support ISO 26262 ASIL-D compliance through its dual-core lockstep CPU, ECC-protected flash and parity-protected SRAM, Safety Support Core (SSC), and built-in self-test capabilities. Renesas provides FMEDA reports, safety manuals, and diagnostic coverage analysis specifically for the R7F7010223AFE#BA4 to assist in functional safety validation. It is also qualified to AEC-Q100 Grade 1 for automotive use.
Does the R7F7010223AFE#BA4 support CAN FD communication?
Yes, the R7F7010223AFE#BA4 integrates multiple CAN FD controllers compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps and payloads up to 64 bytes. These controllers feature message RAM with configurable filters, loopback modes for self-test, and error counters accessible via dedicated registers - all essential for ASIL-D communication in powertrain networks.
What is the maximum operating frequency of the R7F7010223AFE#BA4?
The R7F7010223AFE#BA4 operates at a maximum CPU frequency of 120 MHz, achieved using an on-chip PLL driven by an external 4–20 MHz crystal connected to the CLKIN/CLKOUT pins. The PLL supports fractional division for precise clock generation, and the device includes clock failure detection that triggers a safety interrupt or reset if the main clock deviates beyond ±10% tolerance.
How is flash memory protected against corruption in the R7F7010223AFE#BA4?
The R7F7010223AFE#BA4 implements full 2 MB flash ECC with single-error correction and double-error detection (SEC-DED) on every read/write access. Flash write operations require unlock sequences and are protected by region-based access control. Additionally, the device supports background CRC checking and flash BIST for production and runtime verification - all part of its ASIL-D safety architecture.
Is the R7F7010223AFE#BA4 pin-compatible with other RH850/F1KH-D8 variants?
Yes, the R7F7010223AFE#BA4 uses the same 176-pin LQFP package and pin assignment as other RH850/F1KH-D8 members including R7F7010213AFE#BA4 and R7F7010233AFE#BA4. This enables drop-in replacement within the same family for memory-scaling decisions, with identical power, ground, reset, clock, and debug pin locations - simplifying PCB reuse across ECU variants.
