Overview

R7F701380EAFP-C#BA2 from Renesas Electronics is a 32-bit RH850/P1M-E automotive microcontroller featuring a dual-core lockstep CPU, 4 MB on-chip flash memory, and integrated safety mechanisms including ECC for flash and RAM, MPU, and FIT-based error detection. It operates at up to 160 MHz, supports ASIL-D compliance per ISO 26262, and targets engine control units (ECUs) requiring functional safety certification.

For engineers reviewing the R7F701380EAFP-C#BA2 datasheet, R7F701380EAFP-C#BA2 pinout, R7F701380EAFP-C#BA2 application, or R7F701380EAFP-C#BA2 equivalent, key selection criteria include dual-core lockstep execution integrity, ASIL-D ready safety peripherals (FSM, ESM, CRC), 4 MB flash with background programming, and automotive-grade AEC-Q100 Grade 1 qualification across –40°C to +125°C ambient.

Technical Context

The R7F701380EAFP-C#BA2 implements two identical RH850 G3M cores in lockstep mode with real-time comparison and fault reporting via the Error Signaling Module (ESM). Its safety architecture includes a dedicated Fault Safety Monitor (FSM) that validates core instruction flow, memory access integrity, and peripheral register consistency.

It integrates a 12-bit, 48-channel ADC with hardware-triggered sampling, multiple CAN FD controllers (up to 6 channels), and a flexible timer array (GPTA) supporting PWM generation, input capture, and quadrature decoding - all with built-in self-test and diagnostic coverage aligned to ISO 26262 ASIL-D requirements.

FAQ

What is the maximum operating temperature range certified for the R7F701380EAFP-C#BA2?

The R7F701380EAFP-C#BA2 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating applies to the full device including CPU, flash, RAM, and all integrated peripherals, and is validated through accelerated stress testing per JEDEC JESD22 standards. The R7F701380EAFP-C#BA2 maintains functional safety integrity across this entire range when used within specified voltage and thermal design limits.

Does the R7F701380EAFP-C#BA2 support CAN FD with bit rate switching?

Yes, the R7F701380EAFP-C#BA2 integrates six independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting bit rate switching - allowing arbitration phase at up to 1 Mbps and data phase at up to 5 Mbps. Each controller includes dedicated message RAM, hardware filtering, and built-in CRC calculation for both classic CAN and FD frames. The R7F701380EAFP-C#BA2 also provides timestamping and loopback test modes for protocol validation.

How does the R7F701380EAFP-C#BA2 implement functional safety for ASIL-D compliance?

The R7F701380EAFP-C#BA2 achieves ASIL-D readiness through hardware-enforced redundancy and monitoring: dual RH850 G3M cores execute identical code in lockstep with cycle-accurate comparison; the Fault Safety Monitor (FSM) validates CPU pipeline states and memory transactions; Flash and SRAM include ECC; and the Error Signaling Module (ESM) aggregates faults for safe state entry. All safety mechanisms are documented in the R7F701380EAFP-C#BA2 Functional Safety Manual (R01US0157EJ).

What debug and trace capabilities are available on the R7F701380EAFP-C#BA2?

The R7F701380EAFP-C#BA2 supports Nexus Class 3+ debug interface with real-time trace via Embedded Trace Macrocell (ETM), including instruction trace, data trace, and program flow analysis. It also provides SWD/JTAG for boundary scan and flash programming, plus dedicated safety debug ports accessible only in secure debug mode. The R7F701380EAFP-C#BA2 allows concurrent debugging of both lockstep cores with cross-triggering and trace synchronization.

Is the R7F701380EAFP-C#BA2 pin-compatible with other RH850/P1M-E variants?

Yes, the R7F701380EAFP-C#BA2 uses the 176-pin LQFP package shared across the RH850/P1M-E series, including R7F701374EAFP-C#BA2 and R7F701382EAFP-C#BA2. Pin functions are fully compatible for power, ground, reset, clock, JTAG, and primary peripheral signals (CAN FD, ADC, GPTA). However, some secondary alternative functions differ between variants, so PCB layout must verify signal mapping against the specific variant's pin function table in the R7F701380EAFP-C#BA2 Hardware User's Manual.
