Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D97E3A01CFB#AC0 | LQFP-144 package (vs. LQFP-176); reduced pin count (144 vs. 176); identical core, memory, and peripheral specs except missing SDHI and second CAN FD channel. | Suitable for space-constrained designs where SDHI and dual CAN FD are not required - e.g., compact HMI panels or single-bus gateways. | Select when PCB footprint and BOM cost are prioritized over peripheral flexibility and future upgrade path. |
| R7FA6M5BH3CFC#AC0 | RA6M5 series (Arm Cortex-M33), 1 MB flash, 256 KB SRAM, single CAN FD, no TSIP-Lite (uses RA Security Library instead), different pinout and peripheral mapping. | Targets cost-sensitive industrial IoT endpoints with lower security assurance requirements - lacks hardware root-of-trust and dual-bank flash update capability. | Select only if migrating to Renesas RA ecosystem and accepting software-based crypto and simplified security model. |
Compared with R7FS5D97E3A01CLK#AC0, the R7FS5D97E3A01CFB#AC0 offers identical functionality in a smaller package but sacrifices SDHI and one CAN FD channel, while the R7FA6M5BH3CFC#AC0 trades hardware security and memory capacity for lower unit cost and Cortex-M33-based TrustZone isolation - neither is pin-compatible nor drop-in replaceable.

The R7FS5D97E3A01CLK#AC0 and R7FS5D97E3A01CFB#AC0 share identical core architecture, memory size (2 MB flash, 512 KB SRAM), and peripheral feature set, but differ in package and pin count: the R7FS5D97E3A01CLK#AC0 uses LQFP-176 with full peripheral access (including SDHI and dual CAN FD), while the R7FS5D97E3A01CFB#AC0 uses LQFP-144 and omits SDHI and one CAN FD channel. They are not pin-compatible.
Which communication interfaces with hardware acceleration are integrated into the R7FS5D97E3A01CLK#AC0?
The R7FS5D97E3A01CLK#AC0 integrates hardware-accelerated CAN FD (dual channels), USB 2.0 full-speed (with integrated PHY), SD Host Interface (SDHI), Quad SPI (QSPI), and Ethernet MAC (RMII). All are implemented in dedicated peripheral blocks with DMA support and interrupt-driven operation - no software polling or bit-banging is required for basic functionality. The R7FS5D97E3A01CLK#AC0 also includes a hardware cryptographic engine for AES-256, SHA-256, RSA-2048, and ECC.
Is the R7FS5D97E3A01CLK#AC0 qualified for industrial temperature operation?
Yes, the R7FS5D97E3A01CLK#AC0 is rated for industrial temperature operation from −40°C to +105°C, as confirmed in Renesas' official datasheet and product brief. This rating applies across all specified operating voltages (3.0–3.6 V) and includes full functionality of flash, SRAM, peripherals, and crypto engine within that range. The R7FS5D97E3A01CLK#AC0 is classified as "Standard" grade per Renesas' quality policy and is not intended for automotive safety-critical use.
