FAQ

What is the maximum operating frequency of the R5S726A0P216FP#VZ?

The R5S726A0P216FP#VZ operates at a maximum frequency of 200 MHz, achieved via its on-chip PLL synthesizing from an external 4–20 MHz crystal or clock source. This frequency is fully supported across the entire –40°C to +105°C industrial temperature range and enables 320 MIPS of SH-2A core performance for real-time motor control loops.

Does the R5S726A0P216FP#VZ include a hardware floating-point unit?

Yes, the R5S726A0P216FP#VZ integrates a full IEEE 754-compliant floating-point unit (FPU) supporting both single- and double-precision arithmetic. This FPU is tightly coupled to the SH-2A core and eliminates software emulation overhead - critical for executing complex trigonometric, exponential, and matrix operations in real-time motion control firmware running on the R5S726A0P216FP#VZ.

How many CAN FD interfaces does the R5S726A0P216FP#VZ support?

The R5S726A0P216FP#VZ supports two independent CAN FD controllers compliant with ISO 11898-1:2015, each capable of up to 5 Mbps data phase rates. These controllers feature dedicated message RAM, hardware FIFOs, and error counters - enabling concurrent use for real-time actuator coordination and diagnostics without CPU intervention on the R5S726A0P216FP#VZ.

What is the flash memory capacity and endurance rating of the R5S726A0P216FP#VZ?

The R5S726A0P216FP#VZ includes 2 MB of on-chip flash memory rated for 100,000 write/erase cycles and 20-year data retention at +85°C. It supports dual-bank operation, allowing background programming and safe firmware updates without halting real-time execution - a key reliability feature for field-upgradable industrial systems using the R5S726A0P216FP#VZ.

Is the R5S726A0P216FP#VZ qualified for automotive applications?

No, the R5S726A0P216FP#VZ is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial applications such as motor drives and factory automation. It is not AEC-Q100 qualified nor designated for automotive safety-critical systems; for automotive use, Renesas recommends the RH850/F1K series instead of the R5S726A0P216FP#VZ.
