Overview
R7F701380EAFP-C#KA2 from Renesas Electronics is a 32-bit RH850/P1M-E Group automotive microcontroller featuring a dual-core lockstep CPU, 4 MB on-chip flash memory, 512 KB SRAM, and integrated safety mechanisms including ECC for memory, error injection test support, and ISO 26262 ASIL-D ready hardware architecture. It operates at up to 160 MHz, supports CAN FD (up to 5 channels), and targets safety-critical powertrain and chassis control applications.
For engineers reviewing the R7F701380EAFP-C#KA2 datasheet, R7F701380EAFP-C#KA2 pinout, R7F701380EAFP-C#KA2 application, or R7F701380EAFP-C#KA2 equivalent, key selection criteria include ASIL-D compliance evidence, dual-core lockstep timing behavior, flash ECC coverage scope, CAN FD channel count with time-triggered capability, and package-specific thermal derating curves under automotive ambient conditions.
Technical Context
The R7F701380EAFP-C#KA2 implements two identical RH850G3M cores operating in lockstep mode with cycle-by-cycle comparison and fault detection logic, enabling real-time fault containment. It integrates a dedicated Safety Support Core (SSC) for independent monitoring of CPU execution, memory integrity, and peripheral health.
Hardware safety features include end-to-end data path protection with parity/ECC on all on-chip memories (flash, SRAM, cache), configurable window watchdog timers, memory protection units per core, and diagnostic firmware support via the Built-in Self-Test (BIST) engine and Failure Mode Effect and Diagnostic Analysis (FMEDA)-aligned test libraries.

FAQ
What automotive safety standards does the R7F701380EAFP-C#KA2 support?
The R7F701380EAFP-C#KA2 is designed to support ISO 26262 ASIL-D compliance through integrated hardware safety features including dual-core lockstep execution, ECC on all on-chip memories, Safety Support Core (SSC) monitoring, and FMEDA-aligned diagnostic libraries. It meets AEC-Q100 Grade 1 qualification (−40°C to +125°C) and includes built-in self-test capabilities required for systematic safety analysis. The R7F701380EAFP-C#KA2 documentation provides safety manual and hardware abstraction layer (HAL) drivers to accelerate functional safety certification.
Does the R7F701380EAFP-C#KA2 support over-the-air (OTA) firmware updates?
Yes, the R7F701380EAFP-C#KA2 supports secure OTA updates via its 4 MB on-chip flash memory with ECC protection and SWAP functionality. The flash architecture enables atomic sector swapping, allowing validated firmware images to be written in background while the active application continues running. This capability, combined with the Safety Support Core's runtime integrity checks, ensures that the R7F701380EAFP-C#KA2 maintains functional safety during update cycles without requiring system reset or external supervision.
What is the maximum CAN FD bit rate supported by the R7F701380EAFP-C#KA2?
The R7F701380EAFP-C#KA2 supports CAN FD up to 5 Mbps on all five integrated CAN FD channels, compliant with ISO 11898-1:2015. Each channel operates independently with configurable bit timing, flexible data length (up to 64 bytes), and CRC-17 error detection. The R7F701380EAFP-C#KA2 also supports time-triggered communication scheduling, ensuring deterministic latency for safety-critical messages such as brake torque commands in brake-by-wire systems.
How does the R7F701380EAFP-C#KA2 handle memory errors in safety-critical applications?
The R7F701380EAFP-C#KA2 implements end-to-end ECC protection on all on-chip memories: 4 MB flash uses SEC-DED (single-error correction, double-error detection), 512 KB SRAM uses ECC with scrubbing, and instruction/data caches include parity checking. When an uncorrectable error is detected, the R7F701380EAFP-C#KA2 triggers a safety interrupt and initiates controlled shutdown or fail-safe state transition via the Safety Support Core. Correctable errors are logged and reported without service interruption - a key requirement for ASIL-D compliance verified in the R7F701380EAFP-C#KA2 safety manual.
Is the R7F701380EAFP-C#KA2 pin-compatible with other RH850/P1M-E devices?
No, the R7F701380EAFP-C#KA2 is not pin-compatible with other RH850/P1M-E variants due to differences in peripheral mapping, power domain routing, and safety monitor signal allocation. While it shares the same 176-pin LQFP package footprint, pin functions such as CAN FD channel assignment, ADC input grouping, and safety-related signals (e.g., SSC_ERR, LOCKSTEP_FAIL) are unique to the R7F701380EAFP-C#KA2 configuration. Migration requires PCB redesign and firmware adaptation - confirmed in the RH850/P1M-E Group User's Manual Hardware (Rev.1.20, Mar 2018) section 2.1.
