Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D97E3A01CFB#BA0 | Same die, but with 4 MB flash and 1 MB SRAM - no change in peripheral set or package. | Suitable for applications requiring larger OTA image storage or extended runtime buffers (e.g., audio streaming gateways). | Select when firmware size exceeds 2 MB or when large RAM buffers are needed for protocol translation stacks. |
| R7FA6M5BH3CFC#AA0 | RA6M5 (Arm Cortex-M33) with 1 MB flash, 512 KB SRAM, same crypto engine, but no Ethernet MAC or CAN FD - LQFP-100 package. | Better suited for cost-sensitive, lower-pin-count applications where Ethernet/CAN FD are not required (e.g., sensor nodes). | Choose for simplified BOM and smaller PCB footprint when advanced connectivity is unnecessary. |
Compared with R7FS5D97C3A01CFB#BA0, the R7FS5D97E3A01CFB#BA0 offers double flash/SRAM for complex firmware without altering layout, while the R7FA6M5BH3CFC#AA0 trades connectivity and pin count for lower cost and power - making it viable only where Ethernet and CAN FD are omitted.

FAQ
What is the maximum operating frequency of the R7FS5D97C3A01CFB#BA0?
The R7FS5D97C3A01CFB#BA0 operates at a maximum CPU frequency of 200 MHz using its internal PLL with main oscillator input. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) under 2.7–3.6 V supply conditions, as verified in Renesas' Electrical Characteristics table (Section 30.2, Rev.1.40 User's Manual). The R7FS5D97C3A01CFB#BA0 achieves this via a 2-stage PLL with fine-grained division control, supporting deterministic real-time execution in motion control loops.
Does the R7FS5D97C3A01CFB#BA0 support secure boot?
Yes, the R7FS5D97C3A01CFB#BA0 includes a ROM-based secure boot loader that validates digital signatures of the first-stage bootloader using ECDSA-P256 before execution. This feature is enabled via fuse settings and leverages the on-chip TRNG and hardware RSA/ECC accelerators. The R7FS5D97C3A01CFB#BA0 secure boot flow is documented in Application Note R01AN3819JJ0101 and aligns with PSA Certified Level 2 requirements.
What development tools are officially supported for the R7FS5D97C3A01CFB#BA0?
Renesas officially supports the E2 studio IDE with SSP v3.8.0+, CS+ for Synergy, and IAR Embedded Workbench for Arm. Debugging uses the J-Link PRO or Segger J-Link PLUS with SWD interface. The R7FS5D97C3A01CFB#BA0 is validated on the SK-S5D9 starter kit (YRDKSNK5D9) and DK-S5D9 development kit (YRDKSNK5D9-DK). All toolchains provide full register view, RTOS-aware debugging, and flash programming for the R7FS5D97C3A01CFB#BA0.
Is the R7FS5D97C3A01CFB#BA0 pin-compatible with other S5 Series MCUs?
No - the R7FS5D97C3A01CFB#BA0 is not pin-compatible with other S5 Series MCUs due to differences in peripheral mapping and pin multiplexing. For example, Ethernet MAC pins on the R7FS5D97C3A01CFB#BA0 occupy positions unused in lower-pin-count variants like R7FS5D67C3A01CBJ#AA0 (LQFP-144). Pin compatibility must be verified per specific variant using the "Pin Assignments" section (Section 1.6) of the R7FS5D97C3A01CFB#BA0 User's Manual Rev.1.40.
What is the qualified temperature grade for the R7FS5D97C3A01CFB#BA0?
The R7FS5D97C3A01CFB#BA0 is qualified for the Industrial temperature grade (−40°C to +85°C) and falls under Renesas' "Standard" quality classification per Notice #6 in the User's Manual. It is not rated for automotive AEC-Q100 or extended temperature ranges. Applications requiring operation beyond +85°C or safety-critical transportation use require formal qualification review and are outside the intended scope of the R7FS5D97C3A01CFB#BA0.
