It supports CAN FD, LIN, SENT, and PSI5 interfaces and is qualified for automotive powertrain and chassis control applications.
For engineers reviewing the R7F701377EAFP-C#KA2 datasheet, R7F701377EAFP-C#KA2 pinout, R7F701377EAFP-C#KA2 application, or R7F701377EAFP-C#KA2 equivalent, key selection criteria include ASIL-B functional safety certification, dual-core lockstep execution integrity, 2 MB flash with ECC, 192 KB RAM with parity, and automotive-grade temperature range (–40°C to +125°C).
Technical Context
The R7F701377EAFP-C#KA2 implements two tightly coupled RH850 G3M cores operating in lockstep mode with real-time comparison logic to detect transient faults. It integrates a dedicated Safety Support Core (SSC) that monitors CPU operation, memory integrity, and peripheral health via dedicated watchdogs and error injection test paths.
Its memory subsystem includes 2 MB code flash with single-bit error correction and double-bit error detection (SEC-DED), 192 KB SRAM with parity protection, and a 32 KB instruction cache with lockable regions. Peripheral safety features include redundant timer modules (GPTA/GPTB), self-test-capable ADCs, and configurable I/O monitoring with fail-safe output states.

How does the R7F701377EAFP-C#KA2 handle functional safety diagnostics?
The R7F701377EAFP-C#KA2 implements layered functional safety diagnostics including core-level lockstep comparison, memory ECC/parity checking, peripheral BIST (built-in self-test) for ADC/DAC/timers, and Safety Support Core (SSC)-driven health monitoring. Diagnostic coverage is configurable per module via safety control registers, and error responses include NMI assertion, safe state entry, or system reset. The R7F701377EAFP-C#KA2 provides dedicated diagnostic interrupt vectors and status flags accessible to safety software without CPU intervention.
Is the R7F701377EAFP-C#KA2 pin-compatible with other RH850/P1M-E variants?
Yes, the R7F701377EAFP-C#KA2 shares the same 176-pin LQFP package and pin assignment with other members of the RH850/P1M-E family including R7F701388EAFP-C#KA2 and R7F701376EAFP-C#KA2. Pin compatibility extends to power, ground, clock, reset, debug (JTAG/Ethernet), and major peripheral signals (CAN FD, LIN, SENT, PSI5, SPI, I²C, UART). Differences exist only in memory size and peripheral count - which are software-configurable - making migration between variants feasible without PCB redesign. The R7F701377EAFP-C#KA2 maintains identical electrical characteristics and timing parameters across compatible variants.
