Technical Context

The R7F7016213AFP-C#AA3 implements a dual-core RH850 G3KH CPU with lockstep comparison logic, enabling real-time fault detection. It integrates a 2-channel CAN FD controller supporting ISO 11898-1:2015, a 16-bit ADC with 24 channels and 1 μs conversion time, and a 32-bit watchdog timer with windowed operation and independent clock source.

Its safety architecture includes memory built-in self-test (MBIST), flash CRC calculation unit, and peripheral I/O monitoring via the Safety Support Unit (SSU). The device uses a 176-pin LQFP package with dedicated safety pins (e.g., LOCKSTEP_ERR, SAFETY_RESET) routed to separate power domains and monitored by external safety controllers.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the R7F7016213AFP-C#AA3?

The R7F7016213AFP-C#AA3 operates at a maximum CPU frequency of 160 MHz. This clock speed is sustained across its full temperature range (–40°C to +125°C) and supports deterministic real-time execution for ASIL-D safety-critical tasks. The R7F7016213AFP-C#AA3 achieves this performance using a dual-core RH850 G3KH architecture with synchronized lockstep operation, ensuring timing predictability without compromising fault detection latency.

Does the R7F7016213AFP-C#AA3 support CAN FD with ISO 11898-1:2015 compliance?

Yes, the R7F7016213AFP-C#AA3 integrates two fully compliant CAN FD controllers meeting ISO 11898-1:2015. Each channel supports arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps, with configurable payloads up to 64 bytes. The R7F7016213AFP-C#AA3 implements hardware CRC generation, bit stuffing, and error confinement - all verified in Renesas' RH850/F1K Hardware User's Manual (Rev.1.10).

What safety certifications does the R7F7016213AFP-C#AA3 hold?

The R7F7016213AFP-C#AA3 is AEC-Q100 Grade 1 qualified and designed to meet ISO 26262 ASIL-D requirements. Its hardware safety features - including dual-core lockstep, Safety Support Unit (SSU), memory BIST, flash ECC, and dedicated safety pins - are documented in Renesas' functional safety manual for the RH850/F1K group. The R7F7016213AFP-C#AA3 itself is not pre-certified, but provides all necessary hardware mechanisms for customer-led ASIL-D certification.

How much on-chip flash and RAM does the R7F7016213AFP-C#AA3 include?

The R7F7016213AFP-C#AA3 includes 2 MB of on-chip flash memory with end-to-end ECC protection and 256 KB of SRAM with parity and optional ECC. Flash supports background CRC verification during normal operation, and RAM includes dedicated error-detection logic that triggers interrupts on single-bit errors. These memory resources are validated for use in ASIL-D applications per the R7F7016213AFP-C#AA3's safety manual and RH850/F1K Hardware User's Manual.

Is the R7F7016213AFP-C#AA3 pin-compatible with other RH850/F1K variants?

No, the R7F7016213AFP-C#AA3 is not pin-compatible with other RH850/F1K variants due to its specific 176-pin LQFP package and unique pin mapping for safety signals (e.g., LOCKSTEP_ERR, SAFETY_RESET). While it shares the same RH850/F1K architecture and register set, pin assignments differ across members of the family - for example, the R7F7016212AFP-C#AA3 uses a 144-pin LQFP. Always verify pinout against the official R7F7016213AFP-C#AA3 datasheet before PCB layout.
