Product details
Overview
R7F7017603AFP-C#BA1 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 automotive ADAS domain controllers requiring high-integrity real-time processing.
For engineers reviewing the R7F7017603AFP-C#BA1 datasheet, R7F7017603AFP-C#BA1 pinout, R7F7017603AFP-C#BA1 application, or R7F7017603AFP-C#BA1 equivalent, key selection considerations include ASIL-D certification status, dual-core lockstep fault detection coverage, flash ECC protection level, CAN FD data-rate support (up to 5 Mbps), and ICUMD-supported crypto algorithms (AES-128/256, SHA-256, RSA-2048).
Technical Context
The R7F7017603AFP-C#BA1 implements two synchronized RH850G3K-H cores operating in lockstep mode with continuous comparison logic and error reporting via FIT interrupt. Its memory subsystem includes 4 MB flash with single-bit error correction and double-bit error detection (SEC-DED), plus 1.5 MB SRAM with parity protection across all banks.
Peripheral integration includes five CAN FD controllers supporting protocol version 1.0, one 100BASE-T1 Ethernet MAC with AVB time-synchronization support, and an intelligent cryptographic unit (ICUMD) that offloads AES-GCM, SHA-256, and ECDSA operations without CPU intervention. All safety-critical peripherals are connected via dedicated fault-tolerant bus matrix with end-to-end CRC protection.

Does the R7F7017603AFP-C#BA1 support CAN FD protocol version 1.0?
Yes, the R7F7017603AFP-C#BA1 supports CAN FD protocol version 1.0 as defined in ISO 11898-1:2015. All five integrated CAN FD controllers handle data rates up to 5 Mbps in the data phase, support flexible data-length payloads (up to 64 bytes), and include built-in bit-rate switching and CRC-17/21 calculation hardware.
What cryptographic algorithms are accelerated by the ICUMD in the R7F7017603AFP-C#BA1?
The ICUMD in the R7F7017603AFP-C#BA1 accelerates AES-128/256 in GCM and CBC modes, SHA-256, ECDSA-P256 signing/verification, and RSA-2048 modular exponentiation. It operates independently of the CPU cores, enabling secure boot validation and TLS 1.2/1.3 handshake processing without impacting real-time task scheduling in the R7F7017603AFP-C#BA1.
What is the maximum operating temperature range for the R7F7017603AFP-C#BA1?
The R7F7017603AFP-C#BA1 is rated for operation from −40°C to +125°C ambient temperature, qualified per AEC-Q100 Grade 1 requirements.

How does the R7F7017603AFP-C#BA1 implement secure boot?
The R7F7017603AFP-C#BA1 uses a ROM-resident bootloader that verifies ECDSA-P256 signatures of firmware images before execution. The root public key is fused into ROM during manufacturing and cannot be modified. Each firmware image must be signed with the corresponding private key, and the R7F7017603AFP-C#BA1 enforces strict hash matching and certificate chain validation before releasing the CPU from reset.
