Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F72671W144FP#V0 | Same SH-2A core and peripheral set, but with ROM-based bootloader instead of Flash-resident boot code; no user-programmable Flash. | Suitable for fixed-function, high-volume automotive modules where firmware is pre-flashed at test. | Select R5F72671W144FP#V0 only if field firmware updates are unnecessary and cost-sensitive production is prioritized. |
| RA6M5GFP144FBG | Arm Cortex-M33 core, 200 MHz, TrustZone security, 1 MB Flash, but lacks native CAN FD and SH-2A FPU performance density. | Better suited for secure IoT edge nodes than legacy automotive CAN networks requiring SH-2A toolchain continuity. | Choose RA6M5GFP144FBG when migrating to Arm ecosystem, requiring PSA Certified security, or needing higher clock speed over FPU-optimized math throughput. |
Compared with R5S72671W144FP#V0, R5F72671W144FP#V0 trades field-upgradability for lower unit cost in static deployments, while RA6M5GFP144FBG offers modern security and Arm toolchain alignment at the expense of SH-2A-specific real-time determinism and CAN 2.0B hardware optimization.

FAQ
What is the maximum operating temperature range for R5S72671W144FP#V0?
R5S72671W144FP#V0 is qualified to AEC-Q100 Grade 2, supporting continuous operation from −40°C to +105°C ambient temperature. This rating applies to the full 144-pin LQFP package and all on-chip peripherals, including the FPU, CAN controllers, and ADC, making it suitable for under-hood automotive applications where thermal management is critical. The device includes on-die temperature monitoring circuitry accessible via dedicated registers.
Does R5S72671W144FP#V0 support CAN FD?
R5S72671W144FP#V0 implements CAN 2.0B protocol only and does not support CAN FD data rates or extended frame formats. Its dual CAN controllers are fully compliant with ISO 11898-1 and support bit rates up to 1 Mbps. While the register architecture is forward-compatible with CAN FD peripherals in later Renesas families, R5S72671W144FP#V0 requires external CAN FD transceivers and software abstraction layers to interoperate with CAN FD networks.
Is R5S72671W144FP#V0 pin-compatible with other SH7267 variants?
R5S72671W144FP#V0 shares identical pin assignment and electrical characteristics with R5S72672W144FP#V0 and R5S72673W144FP#V0, differing only in Flash size (1 MB vs. 2 MB vs. 3 MB) and factory-programmed options. All three variants use the same 144-pin LQFP mechanical footprint, power sequencing, and reset timing, enabling drop-in replacement within the same hardware design when Flash capacity requirements change.
What development tools are officially supported for R5S72671W144FP#V0?
Renesas provides official support for R5S72671W144FP#V0 through the e² studio IDE with CS+ compiler toolchain, Renesas Flash Programmer for programming, and the E2 emulator Lite for debugging. Hardware evaluation is enabled via the YRDKSH7267 reference board, which includes CAN transceivers, USB interface, and JTAG/SWD connectors. Third-party tools like IAR Embedded Workbench also support this device via certified SH-2A configuration files.
How is functional safety addressed in R5S72671W144FP#V0?
R5S72671W144FP#V0 includes hardware features aligned with ISO 26262 ASIL-B requirements: lockstep-capable CPU core (via optional external monitoring), memory ECC/parity, MPU for memory partitioning, BIST for Flash/RAM, and configurable watchdog timers. Renesas provides FMEDA reports, safety manuals, and diagnostic software libraries. However, full ASIL-B compliance requires system-level implementation of fault detection, error correction, and fail-safe state management - R5S72671W144FP#V0 provides the foundational hardware mechanisms but not end-to-end certification out-of-box.
