FAQ
What is the maximum operating frequency of the R7F701377EAFP-C#BA2?
The R7F701377EAFP-C#BA2 operates at a maximum frequency of 160 MHz. This clock speed is achieved using an internal PLL that multiplies an external crystal input (4–20 MHz). At 160 MHz, the R7F701377EAFP-C#BA2 delivers deterministic instruction throughput for time-critical automotive control loops, such as fuel injection timing and ignition spark advance, with cycle times under 6.25 µs per instruction.
Does the R7F701377EAFP-C#BA2 support CAN FD, and what data rates are achievable?
Yes, the R7F701377EAFP-C#BA2 integrates three fully compliant CAN FD controllers supporting ISO 11898-1:2015. Each channel achieves up to 5 Mbps in the data phase while maintaining 1 Mbps arbitration phase compatibility. This enables high-bandwidth sensor/actuator communication in modern powertrain systems without requiring external protocol translators or additional CAN controllers.
What safety certifications does the R7F701377EAFP-C#BA2 meet?
The R7F701377EAFP-C#BA2 is designed to support ASIL-B compliance per ISO 26262:2018 Part 5. It includes hardware safety mechanisms such as dual-core lockstep execution, memory BIST, flash and RAM ECC, clock and voltage monitoring, and dedicated error signaling registers. While certification is system-level, the R7F701377EAFP-C#BA2 provides the necessary hardware building blocks to achieve ASIL-B in properly architected automotive ECUs.
How many SENT channels does the R7F701377EAFP-C#BA2 support, and are they configurable?
The R7F701377EAFP-C#BA2 supports eight SENT interface channels, each configurable as either input or output via dedicated control registers. These channels operate independently and support standard SENT frame formats (single-edge nibble transmission) for direct connection to automotive pressure, temperature, and position sensors - eliminating the need for external SENT interface ICs and reducing system-level BOM cost and PCB area.
What is the operating temperature range and AEC-Q100 grade for the R7F701377EAFP-C#BA2?
The R7F701377EAFP-C#BA2 is qualified per AEC-Q100 Grade 1, with an operating ambient temperature range of −40°C to +125°C. This qualification ensures reliable operation in under-hood automotive environments, including proximity to engines and transmissions where thermal stress and vibration are significant. The device's thermal design and packaging meet stringent automotive reliability and lifetime requirements for multi-year vehicle service life.
