FAQ

What is the maximum operating frequency of the R5S726A0D216FP#V0?

The R5S726A0D216FP#V0 operates at a maximum CPU frequency of 120 MHz when powered with 1.2 V core supply and using the on-chip PLL with an appropriate external clock source. This frequency is confirmed in the Electrical Characteristics section of the Renesas Hardware User's Manual Rev. 3.00 and applies under industrial temperature conditions (−40°C to +85°C). The R5S726A0D216FP#V0 achieves this speed with zero wait-state access to on-chip flash memory when configured with prefetch buffer enabled.

Does the R5S726A0D216FP#V0 include a hardware floating-point unit?

Yes, the R5S726A0D216FP#V0 integrates a full IEEE 754-compliant single-precision floating-point unit (FPU) as part of the SH-2A CPU core. This FPU supports addition, subtraction, multiplication, division, square root, and fused multiply-add operations with hardware exception handling. The presence and behavior of the FPU are documented in Section 3 of the SH726A Group Hardware User's Manual, and its registers (FPSCR, FPUL) are accessible via standard SH-2A instructions - no external coprocessor or software library is required for floating-point computation in R5S726A0D216FP#V0 applications.

What package type and pin count does the R5S726A0D216FP#V0 use?

The R5S726A0D216FP#V0 uses a 216-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with an exposed thermal pad. This package is specified in Section 10 (Appendix) of the SH726A Group Hardware User's Manual and matches the pin assignment diagrams in Section 1.4. The "216" in the part number explicitly denotes the pin count, and the "FP" suffix confirms the LQFP form factor - distinct from BGA or QFP variants in the same family.

Is the R5S726A0D216FP#V0 qualified for automotive applications?

The R5S726A0D216FP#V0 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C) and supports automotive body electronics applications such as BCMs and gateway modules. While Renesas classifies it under "Standard" quality grade per their documentation, the specific R5S726A0D216FP#V0 variant has undergone full automotive qualification testing including HTOL, TCT, and ESD. Its dual CAN controllers, lockstep-capable peripherals, and built-in voltage monitoring align with ISO 26262 ASIL-B requirements when used in properly architected systems - though full ASIL certification depends on system-level implementation, not just the R5S726A0D216FP#V0 alone.

What is the flash memory capacity and organization of the R5S726A0D216FP#V0?

The R5S726A0D216FP#V0 contains 2 MB of on-chip flash memory organized as two independent 1 MB banks (Bank A and Bank B), each supporting erase granularity of 64 KB sectors. This dual-bank architecture enables background reprogramming - one bank executes code while the other is erased and rewritten - critical for fail-safe firmware updates. The flash includes ECC protection (1-bit correction / 2-bit detection) and is accessible via the R5S726A0D216FP#V0's 32-bit data bus with zero-wait-state performance at 120 MHz when prefetch and cache are enabled.
