Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7017093AFP-C | Same 176-pin LQFP package and RH850/F1KH-D8 core, but with 6 MB Code Flash and no Trace RAM | Lacks trace capability and reduced firmware storage; suitable for cost-sensitive ASIL-B applications without full ASIL-D toolchain requirements | Select R7F7017093AFP-C when trace debugging is unnecessary and code size remains under 6 MB |

FAQ
What is the operating temperature range for R7F7017083AFP-C#KA1?
R7F7017083AFP-C#KA1 is qualified for −40°C to +105°C ambient operation per AEC-Q100 Grade 2, supporting deployment in under-hood engine control units and chassis modules exposed to thermal stress. The device maintains full functionality across this range with internal voltage regulators and thermal monitoring circuits.
Does R7F7017083AFP-C#KA1 support hardware-based functional safety certification?
Yes, R7F7017083AFP-C#KA1 is developed as a Safety Element out of Context (SEooC) per ISO 26262:2018 Part 2, with documented FMEDA, safety mechanisms including lockstep CPU comparison, ECC on all memories, clock/fault monitors, and hardware guards (IPG/PEG). Full ASIL-D compliance requires system-level integration per customer safety case.
How does the Intelligent Cryptographic Unit Master D (ICUMD) function in R7F7017083AFP-C#KA1?
In R7F7017083AFP-C#KA1, ICUMD operates as an isolated secure domain with its own RH850 G3K CPU, AES-128/256 engines, SHA-256 accelerator, and TRNG. It enforces hardware separation between secure and non-secure worlds, enabling secure boot, key provisioning, and encrypted firmware updates without exposing secrets to the main application cores.
Can R7F7017083AFP-C#KA1 execute AUTOSAR Classic and Adaptive platforms simultaneously?
R7F7017083AFP-C#KA1 supports AUTOSAR Classic natively via its dual-core lockstep configuration and ASIL-D runtime environment. AUTOSAR Adaptive execution requires external Linux-capable SoC; however, R7F7017083AFP-C#KA1 can serve as a trusted offload processor for safety-critical adaptive services like secure communication management or sensor preprocessing.
What debug and trace capabilities does R7F7017083AFP-C#KA1 provide?
R7F7017083AFP-C#KA1 integrates on-chip debug (OCD), boundary scan (IEEE 1149.1), and 32 KB Trace RAM for real-time instruction and data trace capture. It supports Nexus Class 3+ interface for external debug probes, enabling cycle-accurate analysis of dual-core execution, interrupt latency, and memory access patterns during ASW validation.
