FAQ

What is the maximum operating frequency of the R5S726B1P216FP#VZ?

The R5S726B1P216FP#VZ operates at a maximum frequency of 160 MHz when using the on-chip PLL with an external 8 MHz crystal. This frequency is fully supported across the industrial temperature range (−40°C to +85°C) and enables 294.5 DMIPS performance for demanding real-time control tasks. The R5S726B1P216FP#VZ achieves this speed with guaranteed timing margins per Renesas' Electrical Characteristics specification.

Does the R5S726B1P216FP#VZ include a hardware floating-point unit?

Yes, the R5S726B1P216FP#VZ integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This FPU accelerates mathematical operations including division, square root, and trigonometric functions-critical for field-oriented motor control algorithms. The R5S726B1P216FP#VZ uses the same FPU architecture documented in the SH-2A FPU Software Manual (Rev. 3.00).

What package type and pin count does the R5S726B1P216FP#VZ use?

The R5S726B1P216FP#VZ is housed in a 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with an exposed thermal pad. This package matches the mechanical footprint of other SH726B-series devices and supports standard reflow soldering profiles. Pin assignments-including dedicated VCC/VSS pairs, ADC inputs, and CAN/USB signals-are defined in Section 1.4 (Pin Assignment) of the SH726A/B Hardware User's Manual.
