FAQ
What safety certifications does the R7F701375EAFP-C#BA2 hold?
The R7F701375EAFP-C#BA2 is certified to ISO 26262 ASIL-B for hardware elements. Its dual-core lockstep architecture, memory ECC, and built-in diagnostic monitors meet Part 5 requirements without external safety components. Renesas provides FMEDA reports and safety manuals to support system-level ASIL decomposition. The R7F701375EAFP-C#BA2 is not certified to ASIL-D; higher integrity levels require additional hardware redundancy or software diversity.
Does the R7F701375EAFP-C#BA2 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the R7F701375EAFP-C#BA2 integrates two fully compliant CAN FD controllers supporting data rates up to 5 Mbps in the data phase and classical CAN up to 1 Mbps. Each channel includes TX/RX buffers, bit-rate switching logic, and CRC calculation per ISO 11898-1:2015 Annex C. The R7F701375EAFP-C#BA2 also supports CAN FD frame filtering and error confinement modes required for automotive network gateways.
What is the maximum operating frequency and voltage tolerance of R7F701375EAFP-C#BA2 I/O pins?
The R7F701375EAFP-C#BA2 operates at a maximum CPU frequency of 160 MHz and supports 5V-tolerant I/O pins across all VDDIO domains. Input pins accept voltages from –0.3 V to 5.5 V, with Schmitt-trigger hysteresis for noise immunity. This allows direct interfacing with legacy 5V automotive sensors and actuators without level-shifting circuitry. The R7F701375EAFP-C#BA2 maintains this tolerance across its full operating temperature range (–40°C to +125°C).
How does the R7F701375EAFP-C#BA2 handle SENT sensor communication?
The R7F701375EAFP-C#BA2 includes four dedicated SENT receiver channels supporting standard SENT frames (SAE J2716) with 12-bit resolution and programmable sampling windows. Each channel independently decodes pulse-width modulated signals from pressure, temperature, or position sensors, storing results in dedicated registers with timestamping. The R7F701375EAFP-C#BA2 supports both unidirectional and bidirectional SENT protocols and includes automatic frame synchronization recovery.
Is the R7F701375EAFP-C#BA2 pin-compatible with other RH850/P1M-E variants?
Yes, the R7F701375EAFP-C#BA2 shares identical 176-pin LQFP packaging, pin assignment, and electrical characteristics with other members of the RH850/P1M-E family, including R7F701384EAFP-C#BA2 and R7F701376EAFP-C#BA2. This enables drop-in replacement for flash capacity upgrades or feature-set adjustments without PCB redesign. The R7F701375EAFP-C#BA2 maintains full mechanical and thermal compatibility across the family.
