FAQ
What is the maximum operating frequency of the R7F7010303AFP#AA4?
The R7F7010303AFP#AA4 operates at a maximum CPU frequency of 120 MHz. This clock speed is achieved via an on-chip PLL that multiplies an external 8–20 MHz crystal input. The 120 MHz execution capability ensures deterministic timing for powertrain control loops, such as fuel injection and ignition timing, within strict real-time deadlines defined by ISO 26262.
Does the R7F7010303AFP#AA4 support CAN FD, and what data rates does it achieve?
Yes, the R7F7010303AFP#AA4 integrates four CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports arbitration phase up to 1 Mbps and data phase up to 5 Mbps. This enables high-bandwidth communication with modern engine ECUs and ADAS subsystems while maintaining backward compatibility with classical CAN 2.0B networks.
Is the R7F7010303AFP#AA4 qualified for automotive applications, and what standards does it meet?
Yes, the R7F7010303AFP#AA4 is AEC-Q100 Grade 1 qualified (–40°C to +125°C) and designed to support ISO 26262 ASIL-B safety goals. Its dual-core lockstep architecture, ECC-protected memory, and integrated Safety Monitor Unit (SMU) provide the hardware mechanisms required for systematic fault detection and safe state entry - verified through Renesas' certified functional safety package.
What types of on-chip memory does the R7F7010303AFP#AA4 include, and how is it protected?
The R7F7010303AFP#AA4 includes 1.5 MB of on-chip flash memory and 128 KB of SRAM, both protected with error-correcting code (ECC). Flash supports 100,000 write/erase cycles and features secure boot with hash-based authentication. SRAM ECC detects and corrects single-bit errors and detects double-bit errors - essential for maintaining data integrity in ASIL-B applications running on the R7F7010303AFP#AA4.
Does the R7F7010303AFP#AA4 have built-in SENT interface support, and how many channels are available?
Yes, the R7F7010303AFP#AA4 includes four integrated SENT receivers with hardware timestamping at 10 ns resolution. These channels directly decode standardized Single Edge Nibble Transmission signals from crankshaft, camshaft, and throttle position sensors - eliminating the need for external SENT decoder ICs and reducing system BOM and layout complexity in engine management designs using the R7F7010303AFP#AA4.
