FAQ

What is the maximum operating frequency of the R5S726A2D216FP#V0?

The R5S726A2D216FP#V0 operates at a maximum system clock frequency of 120 MHz, achieved via its on-chip PLL with programmable multiplication factor (×1 to ×8) from an external 1–20 MHz clock source. This frequency is fully supported across the full industrial temperature range (−40°C to +85°C) with appropriate voltage regulation and PCB layout practices.

Does the R5S726A2D216FP#V0 include hardware floating-point support?

Yes, the R5S726A2D216FP#V0 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 enables efficient execution of complex mathematical operations required in motor control, sensor fusion, and digital signal processing without software emulation overhead.

What package type and pin count does the R5S726A2D216FP#V0 use?

The R5S726A2D216FP#V0 uses a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm pitch and an exposed thermal pad (EPAD) connected to VSS. This package is RoHS-compliant, supports standard reflow soldering profiles, and is validated for use in automotive and industrial applications per J-STD-020D moisture sensitivity level 3.

How many CAN interfaces does the R5S726A2D216FP#V0 support?

The R5S726A2D216FP#V0 supports two independent CAN 2.0B controllers, each with dedicated message object buffers (64 per channel), programmable bit timing, and built-in error counters. Both controllers operate concurrently and can be configured for different baud rates, enabling gateway functionality or redundant network paths in safety-critical systems.

Is the R5S726A2D216FP#V0 qualified for automotive applications?

Yes, the R5S726A2D216FP#V0 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient) and supports automotive-specific features including CAN FD-ready peripherals, fail-safe reset architecture, and memory ECC. While the standard R5S726A2D216FP#V0 operates up to +85°C, Renesas offers automotive-grade variants (e.g., R5S726A2D216FP#V0-A) with extended temperature validation and PPAP documentation.
