FAQ
What is the maximum operating frequency of the R7F7010493AFP#AA3?
The R7F7010493AFP#AA3 operates at a maximum CPU clock frequency of 160 MHz. This speed is achieved using an on-chip PLL that multiplies an external 8–20 MHz crystal reference. The 160 MHz clock enables deterministic execution of real-time control tasks in automotive gateway and body control applications, and is fully supported across all operating voltage and temperature ranges specified in the AEC-Q100 Grade 1 qualification.
Does the R7F7010493AFP#AA3 support functional safety standards?
Yes, the R7F7010493AFP#AA3 is designed to support ISO 26262 ASIL-B compliance. It includes dual-core lockstep execution, ECC-protected flash and RAM, built-in self-test (BIST) for memory and logic, and hardware safety monitors. These features are documented in Renesas' Functional Safety Manual for the RH850/F1KH series and validated through third-party certification reports. The R7F7010493AFP#AA3 itself carries AEC-Q100 Grade 1 qualification for automotive use.
How many CAN FD interfaces does the R7F7010493AFP#AA3 integrate?
The R7F7010493AFP#AA3 integrates three CAN FD controllers. One of these supports time-triggered communication (TTCAN) for deterministic scheduling, while all three support bit rates up to 5 Mbps and feature message RAM with hardware acceptance filtering. This configuration enables robust inter-domain communication in vehicle gateway applications, allowing concurrent handling of powertrain, chassis, and body networks without external bridge ICs.
What type of Ethernet interface is included in the R7F7010493AFP#AA3?
The R7F7010493AFP#AA3 includes two IEEE 802.3-compliant Ethernet AVB MACs with full hardware support for IEEE 802.1AS timestamping and traffic shaping. Each MAC supports MII/RMII interfaces and integrates dedicated DMA channels. This enables low-latency, time-synchronized audio/video streaming and deterministic communication between infotainment, ADAS, and central compute domains - a key requirement for modern zonal vehicle architectures.
Is the R7F7010493AFP#AA3 pin-compatible with other RH850/F1KH variants?
Yes, the R7F7010493AFP#AA3 is pin-compatible with other members of the RH850/F1KH-D8 variant group, including R7F7010533AFP#AA3 and R7F7010483AFP#AA3. All share the same 176-pin LQFP package, identical pin assignments for power, clocks, reset, JTAG, and major peripheral signals (CAN FD, Ethernet, ADC), and compatible electrical characteristics. This allows scalable memory upgrades and design reuse across different firmware complexity tiers within the same hardware platform.
