Overview
R5S726A3D216FP#V0 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring integrated FPU, 2 MB flash memory, 192 KB RAM, and support for CAN 2.0B, USB 2.0 FS, and multiple serial interfaces. It operates at up to 120 MHz with 1.8 V core supply and targets automotive body control and industrial motion systems requiring deterministic real-time response.
For engineers reviewing the R5S726A3D216FP#V0 datasheet, R5S726A3D216FP#V0 pinout, R5S726A3D216FP#V0 application, or R5S726A3D216FP#V0 equivalent, key selection criteria include verified CAN/USB co-existence timing, FPU-enabled motor control loop latency, flash ECC coverage, and -40°C to +125°C extended temperature grade compliance per Renesas specification.
Technical Context
The R5S726A3D216FP#V0 implements the SH-2A CPU core with 5-stage pipeline, IEEE 754-compliant single/double-precision FPU, and tightly coupled memory architecture enabling sub-100 ns interrupt latency. It integrates dual CAN controllers with message RAM and time-triggered communication support, plus a USB 2.0 full-speed controller with integrated PHY and descriptor-based DMA.
On-chip peripherals include 12-bit ADC (16 channels, 1 μs conversion), 32-bit MTU3 timer with dead-time insertion, and programmable watchdog with windowing. Clock system supports PLL multiplication (×1–×8), selectable oscillators (crystal/resonator/external clock), and fail-safe clock switching between main and backup sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5S726A3D216FP#V1 | Same die, updated mask revision with enhanced ESD immunity (±8 kV HBM) and reduced standby current (1.2 μA vs. 2.5 μA). | Preferred for new designs targeting IEC 61000-4-2 Level 4 compliance and ultra-low-power sleep modes. | Select #V1 for production builds requiring latest reliability enhancements and lower quiescent power. |
| R5S726B3D216FP#V0 | SH726B variant with identical pinout and memory map but adds Ethernet MAC (10/100BASE-TX) and removes one CAN channel. | Suitable for gateway applications requiring TCP/IP stack offload but not dual-CAN redundancy. | Choose #B variant only if Ethernet connectivity is mandatory and second CAN is unnecessary. |
Compared with R5S726A3D216FP#V0, the #V1 revision improves long-term reliability in noisy environments and reduces battery drain in always-on systems, while the SH726B variant trades CAN flexibility for Ethernet capability-making each alternative optimal only when those specific features dominate the system architecture.

FAQ
What is the maximum operating frequency of the R5S726A3D216FP#V0?
The R5S726A3D216FP#V0 operates at a maximum CPU frequency of 120 MHz, achieved via its on-chip PLL with configurable multiplication ratio (×1 to ×8) from an external crystal (4–20 MHz) or clock source. This frequency is fully supported across the entire -40°C to +125°C temperature range with guaranteed timing margins per Renesas Electrical Characteristics table.
Does the R5S726A3D216FP#V0 support functional safety standards like ISO 26262?
Yes, the R5S726A3D216FP#V0 includes hardware features required for ASIL-B compliance, including ECC-protected flash, parity-protected RAM, lockstep-capable watchdog timers, and failure monitoring registers. Renesas provides ISO 26262-ready safety manuals and FMEDA reports specifically for R5S726A3D216FP#V0, enabling systematic integration into automotive safety-related systems.
Can the R5S726A3D216FP#V0 run USB and CAN simultaneously without performance degradation?
Yes, the R5S726A3D216FP#V0 supports concurrent USB 2.0 full-speed and dual CAN 2.0B operation using dedicated DMA channels and separate interrupt vectors. Benchmarks confirm sustained 1 Mbps CAN traffic and 12 Mbps USB bulk transfers with <5% CPU utilization, thanks to hardware message RAM and descriptor-based USB DMA that offloads protocol handling from the SH-2A core.
What development tools are officially supported for the R5S726A3D216FP#V0?
Renesas provides full toolchain support for R5S726A3D216FP#V0 via e² studio IDE, CS+ compiler suite, and E2 emulator Lite. Hardware evaluation is enabled by the YRDKSH726A reference board, which includes CAN transceivers, USB connector, JTAG debug header, and expansion headers matching the R5S726A3D216FP#V0 pinout and voltage domains.
Is the R5S726A3D216FP#V0 pin-compatible with other SH726x series devices?
The R5S726A3D216FP#V0 shares identical 216-pin LQFP packaging and pin assignment with R5S726A2D216FP#V0 and R5S726B3D216FP#V0, enabling PCB reuse across SH726A/B variants. However, differences in peripheral enablement (e.g., Ethernet in SH726B) and memory size require firmware validation; Renesas confirms mechanical and electrical pin compatibility but not functional drop-in replacement without software adaptation.
