For engineers reviewing the R7F7010223AFP-C#AA4 datasheet, R7F7010223AFP-C#AA4 pinout, R7F7010223AFP-C#AA4 application, or R7F7010223AFP-C#AA4 equivalent, key selection criteria include ASIL-D certification status, dual-core lockstep execution, on-chip flash ECC, hardware safety monitor (HSM), and automotive-grade qualification per AEC-Q100 Grade 1.

Technical Context

The R7F7010223AFP-C#AA4 implements a dual-core RH850 G3KH CPU architecture with hardware-enforced lockstep operation and dedicated safety checking logic. It includes a memory protection unit (MPU), error-correcting code (ECC) for both flash and SRAM, and a built-in hardware safety monitor (HSM) that independently verifies CPU instruction flow and memory integrity.

Its peripheral set supports automotive domain controllers: two CAN FD controllers with time-triggered communication support, one FlexRay v2.1 controller, four LIN channels, and an Ethernet AVB MAC with IEEE 802.1AS timestamping. All critical peripherals feature redundant clock domains and error-detection registers accessible via the safety management unit (SMU).

FAQ

What is the maximum operating frequency of the R7F7010223AFP-C#AA4?

The R7F7010223AFP-C#AA4 operates at a maximum CPU frequency of 160 MHz. This speed is sustained across its full industrial temperature range (-40°C to +125°C) with full access to on-chip 2 MB flash and 256 KB RAM without wait states, enabled by its 128-bit wide flash interface and dual-bank SRAM architecture. The R7F7010223AFP-C#AA4 achieves this performance while maintaining ASIL-D compliance through continuous lockstep verification.

Does the R7F7010223AFP-C#AA4 support Ethernet AVB with hardware timestamping?

Yes, the R7F7010223AFP-C#AA4 integrates a full Ethernet AVB MAC with IEEE 802.1AS-2011 hardware timestamping support. It provides precise gPTP (generalized Precision Time Protocol) clock synchronization, including hardware-generated timestamps on transmit and receive frames, and a dedicated 64-bit free-running counter for sub-microsecond timing resolution. This capability is natively supported in the R7F7010223AFP-C#AA4 without requiring external PHY enhancements.

What safety certifications apply to the R7F7010223AFP-C#AA4?

The R7F7010223AFP-C#AA4 is certified to ISO 26262:2018 ASIL-D for functional safety, with documentation covering FMEDA, safety analysis reports, and diagnostic coverage metrics. It meets AEC-Q100 Grade 1 reliability requirements (-40°C to +125°C) and includes integrated hardware safety mechanisms: dual-core lockstep, memory ECC, safety management unit (SMU), and hardware safety monitor (HSM). These features are fully implemented and validated in the R7F7010223AFP-C#AA4 silicon.

How many CAN FD interfaces does the R7F7010223AFP-C#AA4 include?

The R7F7010223AFP-C#AA4 includes two independent CAN FD controllers supporting data rates up to 5 Mbps, with flexible bit timing, payload lengths up to 64 bytes, and built-in protocol error detection. Each controller features dedicated message RAM with hardware acceptance filtering, loopback self-test mode, and time-triggered communication (TTCAN) support. Both CAN FD interfaces are accessible in the R7F7010223AFP-C#AA4's FPBGA-324 package with dedicated differential I/O pins.

Is the R7F7010223AFP-C#AA4 pin-compatible with other RH850/F1KH variants?

No, the R7F7010223AFP-C#AA4 is not pin-compatible with other RH850/F1KH variants such as R7F7010213AFP-C#AA4 or R7F7010233AFP-C#AA4. While sharing the same FPBGA-324 package footprint, pin assignments differ significantly due to variant-specific peripheral enablement (e.g., FlexRay presence, Ethernet PHY interface options, and ADC channel count). The R7F7010223AFP-C#AA4 has unique pin mapping documented in Section 2A of the RH850/F1KH Hardware User's Manual Rev.1.30.
