For engineers reviewing the R7F701379EAFP-C#KA2 datasheet, R7F701379EAFP-C#KA2 pinout, R7F701379EAFP-C#KA2 application, or R7F701379EAFP-C#KA2 equivalent, key selection criteria include dual-core lockstep execution integrity, ASIL-D ready safety architecture, 2 MB flash with ECC, CAN FD bandwidth support, and 176-pin LQFP package compatibility with automotive ECU thermal and layout constraints.

Technical Context

The R7F701379EAFP-C#KA2 implements two identical RH850 G3M cores in lockstep mode with real-time comparison logic and error signaling via dedicated safety interrupt outputs. Its memory subsystem includes 2 MB of flash with single-bit error correction and double-bit error detection (SEC-DED), plus 256 KB of SRAM with parity protection and built-in self-test (BIST) coverage for both memories.

Peripheral integration targets functional safety-critical automotive domains: dual CAN FD controllers supporting up to 5 Mbps, four LIN channels, eight SENT receivers, two PSI5 receivers, and a hardware safety monitor (HSM) with independent watchdog and clock failure detection - all accessible via dedicated safety-critical bus segments.

FAQ

What is the maximum operating frequency of the R7F701379EAFP-C#KA2?

The R7F701379EAFP-C#KA2 operates at a maximum CPU frequency of 160 MHz. This applies to both cores in lockstep configuration, with timing verified across the full −40°C to +125°C temperature range and 4.5 V to 5.5 V supply voltage. The R7F701379EAFP-C#KA2 achieves this frequency using on-chip PLL circuitry with jitter specifications compliant with automotive EMC standards.

Does the R7F701379EAFP-C#KA2 support CAN FD, and what is its maximum data rate?

Yes, the R7F701379EAFP-C#KA2 integrates two fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports data rates up to 5 Mbps in FD mode and 1 Mbps in classical CAN mode. The R7F701379EAFP-C#KA2 implements hardware message filtering, TX/RX FIFOs, and automatic retransmission - enabling deterministic handling of high-priority powertrain messages.

What safety certifications does the R7F701379EAFP-C#KA2 target, and what hardware features enable them?

The R7F701379EAFP-C#KA2 is designed to support ISO 26262 ASIL-D compliance. Key enablers include dual-core lockstep CPU with real-time comparison, 2 MB flash with SEC-DED ECC, 256 KB SRAM with parity and BIST, dedicated hardware safety monitor (HSM), and integrated diagnostic library. These features are documented in Renesas' Functional Safety Manual for the RH850/P1M-E Group, and the R7F701379EAFP-C#KA2 is qualified per AEC-Q100 Grade 1.

How many SENT and PSI5 interfaces does the R7F701379EAFP-C#KA2 provide?

The R7F701379EAFP-C#KA2 provides eight SENT receiver channels and two PSI5 receiver channels. All eight SENT inputs support configurable pulse-width decoding and CRC validation per SAE J2716 Rev 3. Both PSI5 receivers support synchronous sampling, frame synchronization, and CRC-checked data reception at up to 125 kbps. This native integration eliminates external interface ICs when connecting to common automotive pressure, temperature, and wheel speed sensors.

What package type and pin count does the R7F701379EAFP-C#KA2 use?

The R7F701379EAFP-C#KA2 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm pitch and an exposed thermal pad. This package is RoHS-compliant and qualified for automotive reflow profiles. The pinout aligns with the RH850/P1M-E Group standard, enabling drop-in replacement within the same family - for example, the R7F701379EAFP-C#KA2 shares identical footprint and signal mapping with R7F701380EAFP-C#KA2 except for flash size and peripheral enablement.
