FAQ

What is the maximum operating frequency of the R7F7016513ABG-C#AC1?

The R7F7016513ABG-C#AC1 operates at a maximum system clock frequency of 160 MHz, achieved via its on-chip PLL using an external 8–20 MHz crystal. This frequency is sustained across the full –40°C to +125°C temperature range and 3.135 V to 3.465 V supply voltage, with timing closure verified in worst-case silicon corner conditions. The R7F7016513ABG-C#AC1 maintains deterministic real-time performance at this speed due to its Harvard architecture and zero-wait-state flash execution.

Does the R7F7016513ABG-C#AC1 support AUTOSAR-compliant MCAL drivers?

Yes, the R7F7016513ABG-C#AC1 is supported by Renesas' official AUTOSAR MCAL 4.3.x and 4.4.x drivers, including modules for DIO, PORT, ADC, GPT, ICU, CAN, LIN, and SENT. These drivers are validated against Vector DaVinci Developer and ETAS ISOLAR-A tools, and include ASIL-B safety certification evidence for use in production AUTOSAR stacks. The R7F7016513ABG-C#AC1's peripheral register layout and interrupt mapping align directly with AUTOSAR OS requirements.

What safety documentation is provided for the R7F7016513ABG-C#AC1?

Renesas provides a complete ISO 26262-5:2018 ASIL-B safety package for the R7F7016513ABG-C#AC1, including FMEDA report, safety manual, hardware safety analysis summary, and diagnostic coverage metrics for all safety mechanisms (lockstep, ECC, BIST, voltage/temp monitors). This documentation is delivered with the device's qualification certificate and is accessible through Renesas' MyRenesas portal upon NDA registration. The R7F7016513ABG-C#AC1's safety features are implemented in hardware and require no runtime software overhead.

Can the R7F7016513ABG-C#AC1 operate without an external crystal?

No-the R7F7016513ABG-C#AC1 requires an external 8–20 MHz fundamental-mode crystal connected to CLKIN/CLKOUT pins for reliable operation. Its on-chip PLL does not support internal RC oscillators as a system clock source; the only fallback is the 125 kHz sub-clock (for RTC only), which cannot drive the CPU or peripherals. Using an external crystal ensures phase noise and jitter performance necessary for CAN FD bit timing accuracy and ADC sampling stability. The R7F7016513ABG-C#AC1's clock tree is designed exclusively around crystal-referenced PLL operation.

What debug interface does the R7F7016513ABG-C#AC1 support?

The R7F7016513ABG-C#AC1 supports JTAG (IEEE 1149.1) and Nexus Class 3+ debug interfaces via its dedicated debug port (pins TDI, TDO, TCK, TMS, TRST, and DBG). It is compatible with Renesas E2 emulator and third-party tools including Lauterbach TRACE32 and iSYSTEM winIDEA. The debug interface supports full visibility into both lockstep cores, real-time trace via SWO, and non-intrusive breakpoints-even during safety-critical task execution. Debug access remains functional in all power modes except deep standby.
