Product details
Overview
R7F701382EAFP-C#BA2 from Renesas Electronics is a 32-bit RH850/P1M-E automotive microcontroller featuring a dual-core lockstep CPU, 2 MB on-chip flash memory, 256 KB RAM, and integrated CAN FD, LIN, and SENT interfaces. It operates at up to 160 MHz, supports ASIL-D functional safety per ISO 26262, and targets engine control units (ECUs) requiring high-integrity real-time processing.
For engineers reviewing the R7F701382EAFP-C#BA2 datasheet, R7F701382EAFP-C#BA2 pinout, R7F701382EAFP-C#BA2 application, or R7F701382EAFP-C#BA2 equivalent, key selection criteria include dual-core lockstep execution, ASIL-D compliance evidence, flash ECC coverage, CAN FD data rate support (up to 5 Mbps), and package-specific thermal resistance for under-hood deployment.
Technical Context
The R7F701382EAFP-C#BA2 implements two identical RH850G3M cores in lockstep mode with hardware-based comparison and error signaling. It integrates a 2 MB code flash with 64-bit ECC, 256 KB SRAM with SEC-DED ECC, and a dedicated Safety Support Core (SSC) for runtime diagnostics including memory BIST, clock monitor, and voltage supervisor.
Peripheral integration includes four CAN FD controllers (with protocol RAM and bit-rate switching), six LIN channels, eight SENT receivers, and a 12-bit ADC with 48 channels and hardware scan sequencing - all accessible via the multi-layer bus matrix with AXI/AHB bridges and configurable access protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon TC397XP-160F300N | Tri-core AURIX architecture with 300 MHz peak, 4 MB flash, no integrated SENT receivers | Requires external SENT interface ICs; broader toolchain support for AUTOSAR Classic | Select when AUTOSAR OS certification and higher compute throughput outweigh integrated SENT cost savings. |
| NXP S32K344UAT0VLQ | Arm Cortex-R52 dual-core, 320 MHz, 4 MB flash, 512 KB RAM, no lockstep - uses split-lock mode instead | Lacks native lockstep; relies on software-managed split-lock and redundant execution for ASIL-D | Select when Arm ecosystem alignment and higher clock frequency are prioritized over hardware lockstep determinism. |
Compared with R7F701382EAFP-C#BA2, the TC397XP offers higher clock speed and larger flash but adds system-level complexity via external SENT components, while the S32K344 trades hardware lockstep for Arm-based split-lock - impacting fault detection latency and safety certification effort.

FAQ
What safety certifications does the R7F701382EAFP-C#BA2 hold?
The R7F701382EAFP-C#BA2 is designed to support ISO 26262 ASIL-D compliance at the system level. It includes hardware safety mechanisms such as dual-core lockstep, ECC on flash and RAM, Safety Support Core (SSC) diagnostics, and clock/voltage monitors. Renesas provides FMEDA reports, safety manuals, and certified compiler toolchains - but final ASIL-D certification requires integration into a validated system architecture and application-specific safety analysis.
Does the R7F701382EAFP-C#BA2 support CAN FD with bit-rate switching?
Yes, the R7F701382EAFP-C#BA2 supports full CAN FD operation including bit-rate switching between arbitration (up to 1 Mbps) and data phases (up to 5 Mbps). Each of its four CAN FD controllers includes dedicated protocol RAM, hardware filtering, and flexible bit-timing configuration registers - enabling seamless transition from legacy CAN networks to high-throughput FD implementations without external transceivers.
How is flash memory protected against corruption in the R7F701382EAFP-C#BA2?
The R7F701382EAFP-C#BA2 employs 64-bit ECC on its 2 MB on-chip flash memory, capable of detecting and correcting multi-bit errors per 64-bit word. Flash access is further secured via write-protection registers, region locking, and secure boot authentication using embedded hash engines. Error events are logged to dedicated status registers and can trigger NMI or safety interrupts for immediate recovery action.
What is the maximum operating temperature rating for the R7F701382EAFP-C#BA2?
The R7F701382EAFP-C#BA2 is rated for operation from −40°C to +125°C ambient temperature and is qualified to AEC-Q100 Grade 1. Its thermal design supports junction temperatures up to +150°C under specified power dissipation, making it suitable for under-hood automotive applications including engine control, transmission, and brake modules where sustained high-temperature exposure occurs.
Can the R7F701382EAFP-C#BA2 interface directly with SENT sensors without external components?
Yes, the R7F701382EAFP-C#BA2 integrates eight dedicated SENT receiver channels compliant with SAE J2716 Rev 3. Each channel accepts standard open-drain SENT signals (0–5 V), performs pulse-width decoding, frame validation, and CRC checking in hardware - eliminating the need for external SENT interface ICs or GPIO-based software decoding and reducing BOM cost and PCB area.
