The R7F7015833AFP-C#KA3 is designed to support ISO 26262 ASIL-D compliance through integrated hardware safety features including dual-core lockstep execution, Safety Support Core (SSC), full ECC on flash and SRAM, built-in self-test (BIST), and fault collection registers. It is AEC-Q100 Grade 1 qualified for operation from −40°C to +125°C, and Renesas provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate functional safety certification of systems using the R7F7015833AFP-C#KA3.

How many CAN FD interfaces does the R7F7015833AFP-C#KA3 include?

The R7F7015833AFP-C#KA3 integrates five independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting data rates up to 5 Mbps. These controllers operate concurrently and can be configured for different bit timing and message filtering schemes, enabling robust high-speed communication across distributed automotive domains such as engine, transmission, and chassis networks - all within a single R7F7015833AFP-C#KA3 device.

What is the maximum operating frequency of the R7F7015833AFP-C#KA3?

The R7F7015833AFP-C#KA3 operates at a maximum CPU frequency of 160 MHz, achieved via an internal PLL fed by an external 4–20 MHz clock source. This clock speed supports deterministic real-time execution of complex control algorithms, including multi-cylinder combustion modeling and fast-loop motor control, while maintaining timing margins for ASIL-D safety checks executed by the Safety Support Core alongside main application code.

Does the R7F7015833AFP-C#KA3 include on-chip flash memory, and what protection features does it offer?

Yes, the R7F7015833AFP-C#KA3 includes 3 MB of embedded flash memory with full single-bit error correction and double-bit error detection (SEC-DED) ECC protection across the entire array. This ECC implementation is hardware-accelerated and transparent to software, ensuring data integrity during read/write operations and meeting ASIL-D fault tolerance requirements. Flash programming and erase functions are accessible via on-chip boot ROM and supported by Renesas' Flash Development Toolkit for R7F7015833AFP-C#KA3.

What package type and pin count does the R7F7015833AFP-C#KA3 use?

The R7F7015833AFP-C#KA3 is housed in a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm pitch. This RoHS-compliant package supports standard surface-mount assembly processes and provides dedicated power/ground pins per domain (core, analog, I/O, safety) to minimize noise coupling. Pin assignments are documented in Section 2A of the RH850/F1KH User's Manual: Hardware (Rev.1.30), and the R7F7015833AFP-C#KA3 pinout is fully compatible with other members of the RH850/F1KH-D8 family.
