FAQ

What is the maximum operating frequency of the R5S72670P144FP#VZ?

The R5S72670P144FP#VZ operates at a maximum CPU clock frequency of 120 MHz when powered within its specified 3.0–3.6 V range and ambient temperature of −40 °C to +105 °C. This frequency is achieved using the on-chip PLL with an external 8 MHz crystal, delivering 196.8 DMIPS performance. The R5S72670P144FP#VZ maintains timing compliance across its full temperature and voltage range without derating.

Does the R5S72670P144FP#VZ include a hardware floating-point unit?

Yes, the R5S72670P144FP#VZ integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This FPU accelerates trigonometric, logarithmic, and matrix operations required for motor control algorithms and sensor fusion. Unlike software-emulated FP, the R5S72670P144FP#VZ FPU executes these operations in dedicated hardware with deterministic latency.

Is the R5S72670P144FP#VZ qualified for automotive applications?

Yes, the R5S72670P144FP#VZ is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C), making it suitable for automotive body electronics, chassis systems, and infotainment gateways. Its High Quality grade designation per Renesas documentation confirms suitability for transportation equipment, and the device includes features such as ECC on Flash, MPU, and watchdog timers aligned with ISO 26262 ASIL-B readiness.

What package type does the R5S72670P144FP#VZ use?

The R5S72670P144FP#VZ uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with an exposed thermal pad. This JEDEC MO-220-compliant package provides mechanical robustness for reflow soldering and thermal performance suitable for sustained 120 MHz operation in enclosed automotive enclosures. Pin assignments match the SH7267 Group's standardized layout across all 144-pin variants.

How much on-chip memory does the R5S72670P144FP#VZ provide?
