FAQ

What is the maximum operating frequency of the R5S72631P200FP?

The R5S72631P200FP operates at a maximum frequency of 200 MHz, achieved via its on-chip PLL clock generator configured from an external 1–20 MHz crystal or clock source. This frequency enables sub-microsecond interrupt latency and real-time execution of complex control algorithms such as field-oriented control in motor drive applications. The R5S72631P200FP maintains timing compliance across its full operating voltage range (3.0–3.6 V) and temperature range (−40°C to +85°C).

Does the R5S72631P200FP include a floating-point unit?

Yes, the R5S72631P200FP integrates a hardware IEEE 754-compliant single-precision floating-point unit (FPU) as part of its SH-2A CPU core. This FPU supports add, multiply, divide, square root, and fused multiply-add operations with full exception handling. It significantly accelerates mathematical computations required in motor control, digital power conversion, and sensor fusion - eliminating the need for software-emulated floating-point libraries and reducing code size and execution time in the R5S72631P200FP.

How many CAN interfaces does the R5S72631P200FP support?

The R5S72631P200FP supports two independent CAN 2.0B controllers, each with dedicated message RAM, acceptance filtering, and bit-rate configuration registers. Both controllers operate concurrently at up to 1 Mbps and comply with ISO 11898-1:2003. They are electrically isolated from the MCU core via dedicated APB bridges, enabling robust multi-network communication in applications like industrial PLC backplanes or vehicle subsystem gateways using the R5S72631P200FP.

What package type is used for the R5S72631P200FP?

The R5S72631P200FP is housed in a 176-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with an exposed thermal pad. This package supports reflow soldering per J-STD-020, provides 144 general-purpose I/O pins, and includes dedicated power/ground planes for noise isolation. Its pin assignment aligns with Renesas' SH7260 Series footprint compatibility, allowing drop-in replacement among R5S7263x variants - a key feature of the R5S72631P200FP's mechanical design.

Is the R5S72631P200FP supported by modern development tools?

Yes, the R5S72631P200FP is supported by Renesas e² studio IDE, CS+ (formerly High-performance Embedded Workshop), and GNU GCC-based toolchains with SH-2A target support. Debugging is enabled via JTAG/SWD interfaces, and low-level drivers are provided in the Renesas Synergy Platform-compatible HAL. While newer Arm-based alternatives offer expanded cloud-connected tooling, the R5S72631P200FP retains full production toolchain support including certified IAR Embedded Workbench v8.x and validated RTOS ports (e.g., Micrium µC/OS-III).
