Product details
Overview
R7F7016453AFP-C#KA1 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring 4 MB flash, 512 KB RAM, and dual-lockstep CPU cores for ASIL-D functional safety compliance. It integrates CAN FD (up to 5 channels), Ethernet AVB, 12-bit ADC (48 ch), and hardware security module (ICUMD). Used in vehicle domain controllers requiring high-integrity real-time control.
For engineers reviewing the R7F7016453AFP-C#KA1 datasheet, R7F7016453AFP-C#KA1 pinout, R7F7016453AFP-C#KA1 application, or R7F7016453AFP-C#KA1 equivalent, key selection criteria include ASIL-D certification status, dual-core lockstep timing behavior, flash ECC coverage, ICUMD cryptographic acceleration, and RH850/F1KH-D8-specific peripheral register mapping per Rev.1.30 Hardware Manual.
Technical Context
The R7F7016453AFP-C#KA1 implements a dual-core RH850 G3KH CPU with lockstep execution and hardware-based fault detection logic. It supports time-triggered execution via the on-chip timer unit (GPT) and includes dedicated safety monitors for memory (ECC), bus (parity), and clock (fail-safe oscillator monitoring).
Peripheral integration includes five CAN FD controllers with protocol offload, one 100BASE-T1 Ethernet MAC with AVB support, and a 48-channel 12-bit SAR ADC with window comparison and scan sequencing - all accessible via dedicated DMA channels with scatter-gather capability and error reporting.

FAQ
What safety certifications does the R7F7016453AFP-C#KA1 hold?
The R7F7016453AFP-C#KA1 is designed to meet ISO 26262:2018 ASIL-D requirements at the hardware level. Renesas provides a certified safety manual (R01UH0622EJxxxx), FMEDA reports, and diagnostic coverage analysis. The R7F7016453AFP-C#KA1 itself is not individually certified; final system-level ASIL-D compliance requires integration per the safety manual and customer-specific validation.
Does the R7F7016453AFP-C#KA1 support Ethernet Time-Sensitive Networking (TSN)?
No, the R7F7016453AFP-C#KA1 supports IEEE 802.1AS (gPTP) and 802.1Qav (credit-based shaper) for Audio Video Bridging (AVB), but does not implement full TSN features such as 802.1Qbv (time-aware shaper) or 802.1Qbu (frame preemption). For TSN, consider the RH850/F1KM-S4-based R7F7016883AFP-C#KA1 or newer RH850/E2x series.
What is the maximum operating temperature range for the R7F7016453AFP-C#KA1?
The R7F7016453AFP-C#KA1 is rated for ambient operating temperature from −40 °C to +125 °C, qualified per AEC-Q100 Grade 1. This rating applies to the full 176-pin LQFP package under specified voltage and derating conditions defined in the electrical characteristics section of the RH850/F1KH Hardware Manual Rev.1.30.
Can the R7F7016453AFP-C#KA1 execute code from external QSPI flash?
No, the R7F7016453AFP-C#KA1 does not support XIP (execute-in-place) from external QSPI flash. Code execution is limited to on-chip flash memory. External memory interfaces (e.g., SDRAM, SRAM) are not provided; expansion must be handled via CAN FD, Ethernet, or SPI-connected peripherals.
Is the ICUMD cryptographic module in the R7F7016453AFP-C#KA1 FIPS 140-2 validated?
The ICUMD module in the R7F7016453AFP-C#KA1 is certified to Common Criteria EAL4+ (certification ID: JISEC-CC-2021-01-001), but it is not FIPS 140-2 validated. For FIPS 140-2 compliance, external co-processors or software-based libraries meeting FIPS requirements must be used alongside the R7F7016453AFP-C#KA1.
