Product details
Overview
R7F7015814AFP-C#BA3 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring dual-core lockstep CPU architecture, 4 MB on-chip flash memory, and ASIL-D functional safety compliance per ISO 26262. It integrates CAN FD (up to 5 channels), Ethernet AVB, and hardware security module (ICUMD) for secure boot and cryptographic acceleration. Used in advanced driver assistance systems (ADAS) electronic control units requiring high-integrity real-time processing.
For engineers reviewing the R7F7015814AFP-C#BA3 datasheet, R7F7015814AFP-C#BA3 pinout, R7F7015814AFP-C#BA3 application, or R7F7015814AFP-C#BA3 equivalent, key selection considerations include ASIL-D certification status, dual-core lockstep fault detection capability, integrated ICUMD cryptographic engine, CAN FD channel count, and 176-pin LQFP package thermal and routing constraints.
Technical Context
The R7F7015814AFP-C#BA3 implements a dual-core RH850G3KH CPU with lockstep execution and hardware-based error detection logic, enabling continuous comparison of core outputs to detect transient faults. It includes dedicated safety mechanisms such as BIST for flash and RAM, ECC for SRAM and instruction cache, and a dedicated Safety Support Core (SSC) for independent monitoring.
Peripherals are partitioned across safety domains: CAN FD controllers support programmable bit timing and loopback self-test modes; Ethernet AVB interface complies with IEEE 802.1AS time synchronization; and the ICUMD block supports AES-128/256, SHA-256, RSA-2048, and true random number generation with tamper detection.

FAQ
What is the maximum operating temperature specification for the R7F7015814AFP-C#BA3?
The R7F7015814AFP-C#BA3 is qualified for operation from −40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. This rating applies to the full 176-pin LQFP package with exposed thermal pad, and thermal design must ensure junction temperature remains within −40°C to +150°C under worst-case power dissipation conditions specified in the datasheet's thermal characteristics table.
Does the R7F7015814AFP-C#BA3 support JTAG debugging in production mode?
Yes, the R7F7015814AFP-C#BA3 retains full JTAG debug access via pins TDI, TDO, TCK, TMS, and TRSTn even in secured production mode. However, debug access is gated by the on-chip security fuse; once the "debug disable" fuse is blown, JTAG functionality is permanently disabled to prevent unauthorized code extraction or modification of the R7F7015814AFP-C#BA3.
How many CAN FD channels does the R7F7015814AFP-C#BA3 integrate, and what is their data rate capability?
The R7F7015814AFP-C#BA3 integrates five independent CAN FD controllers. Each supports programmable bit timing with arbitration phase rates up to 1 Mbps and data phase rates up to 5 Mbps, compliant with ISO 11898-1:2015. All five channels operate concurrently and can be assigned to separate physical transceivers without resource contention.
Is the R7F7015814AFP-C#BA3 pin-compatible with other RH850/F1KH variants?
The R7F7015814AFP-C#BA3 shares the same 176-pin LQFP package and pin assignment with all RH850/F1KH-D8 variants (e.g., R7F7015834AFP-C#BA3), including identical power, ground, clock, reset, and peripheral signal locations. This enables drop-in replacement for flash-capacity upgrades without PCB redesign.
What safety documentation is provided for the R7F7015814AFP-C#BA3 to support ISO 26262 development?
Renesas provides a complete ISO 26262 ASIL-D safety package for the R7F7015814AFP-C#BA3, including FMEDA report, safety manual, hardware safety analysis summary, diagnostic coverage metrics, and safety mechanism implementation guide. These documents are delivered under NDA and accompany the R7F7015814AFP-C#BA3 evaluation kit and production licensing.
