FAQ

What is the maximum operating temperature range certified for the R7F7010223AFP-C#BA4?

The R7F7010223AFP-C#BA4 is qualified per AEC-Q100 Grade 1 with an operating ambient temperature range of -40°C to +125°C. This rating is validated through extended life testing including HTOL (High-Temperature Operating Life) and TC (Temperature Cycling) per JESD22-A108 and JESD22-A104 standards. The R7F7010223AFP-C#BA4 maintains full functionality - including lockstep monitoring, CAN FD timing, and ADC accuracy - across this full range.

Does the R7F7010223AFP-C#BA4 support CAN FD with bit rate switching?

Yes, the R7F7010223AFP-C#BA4 supports ISO 11898-1:2015-compliant CAN FD with bit rate switching. Its four integrated CAN FD controllers allow separate configuration of arbitration phase (up to 1 Mbps) and data phase (up to 5 Mbps), with hardware CRC-17 generation and checking. The R7F7010223AFP-C#BA4 implements time-triggered communication with hardware timestamping accurate to ±1 µs, enabling deterministic scheduling across all CAN FD channels.

How is functional safety implemented in the R7F7010223AFP-C#BA4 for ASIL-B compliance?

The R7F7010223AFP-C#BA4 achieves ISO 26262 ASIL-B compliance through hardware-enforced safety mechanisms: dual-core lockstep with cycle-accurate divergence detection, memory BIST for flash and RAM, ECC for both memories, and a dedicated Safety Support Core (SSC) managing diagnostic coverage reporting. These features are documented in Renesas' certified FMEDA report (Rev. 2.1), which confirms ≥90% SPFM and ≥60% LFM. The R7F7010223AFP-C#BA4 also includes lockstep-aware debug security and independent watchdog timers with separate clock sources.

What package type and thermal characteristics does the R7F7010223AFP-C#BA4 use?

The R7F7010223AFP-C#BA4 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm pitch and an exposed thermal pad (EPAD). Its thermal resistance θ_JA is 28°C/W under standard JEDEC 2S2P board conditions. The EPAD must be soldered to a dedicated thermal plane on the PCB to achieve rated power dissipation of up to 2.8 W at +125°C ambient. Renesas provides detailed layout guidelines for thermal vias and copper fill in the R7F7010223AFP-C#BA4 hardware design manual.

Can the R7F7010223AFP-C#BA4 execute AUTOSAR-compliant software stacks?

Yes, the R7F7010223AFP-C#BA4 is fully compatible with AUTOSAR 4.3 and later releases. Its dual-core lockstep architecture, memory protection unit (MPU), and ASIL-B certified peripherals meet AUTOSAR OS requirements for safety partitions. Renesas provides certified AUTOSAR Basic Software (BSW) modules including CAN FD drivers, E2E protection libraries, and memory abstraction layers - all validated for use with the R7F7010223AFP-C#BA4 in production ECUs.
