Product details
Overview
R7FS5D97C3A01CFP#BA0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S5 Series, featuring 3 MB flash, 512 KB SRAM, integrated FPU, and hardware AES/SHA/TRNG security accelerators. It supports USB 2.0 FS, CAN FD, multiple UART/SPI/I²C interfaces, and operates at up to 240 MHz for real-time industrial HMI and secure IoT edge node applications.
For engineers reviewing the R7FS5D97C3A01CFP#BA0 datasheet, R7FS5D97C3A01CFP#BA0 pinout, R7FS5D97C3A01CFP#BA0 application, or R7FS5D97C3A01CFP#BA0 equivalent, key selection considerations include its 176-pin LQFP package, dual-bank flash with SWAP functionality, CAN FD compliance (ISO 11898-1:2015), and Synergy Software Package (SSP) v3.x integration support.
Technical Context
The R7FS5D97C3A01CFP#BA0 implements a dual-core debug architecture with SWD/JTAG support and CoreSight trace funneling. Its system clock tree integrates PLL, FLL, and multiple independent clock domains (PCLKA/B/C/D, ICLK, BCLK) enabling precise peripheral gating and low-power mode coordination.
Security is implemented via dedicated hardware blocks: AES-128/256 engine with DMA support, SHA-256 accelerator, and TRNG compliant with NIST SP 800-90B. The MCU includes MPU with 8 regions, TrustZone-enabled memory partitioning, and secure boot with signature verification using ECDSA-P256.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D97E3A01CFP#BA0 | Same core, package, and peripherals but with 4 MB flash and 1 MB SRAM - no change in pinout or clock architecture. | Required when firmware image size exceeds 3 MB or application demands >512 KB RAM for large buffers or RTOS heap. | Select if future firmware growth or multi-threaded operation necessitates additional memory headroom. |
| R7FA6M5BH3CFC#AA0 | RA6M5 (Arm Cortex-M33) with TrustZone, 1 MB flash, 384 KB SRAM, same 176-LQFP package - lacks CAN FD and hardware SHA/TRNG. | Suitable for non-automotive secure IoT where CAN FD is unnecessary but PSA Certified Level 2 is mandated. | Choose for PSA-certified designs prioritizing Arm TrustZone over CAN FD bandwidth and legacy Synergy ecosystem compatibility. |
Compared with R7FS5D97C3A01CFP#BA0, the R7FS5D97E3A01CFP#BA0 offers memory scalability without design changes, while the R7FA6M5BH3CFC#AA0 shifts to Armv8-M TrustZone with reduced peripheral set - making it appropriate only when security certification outweighs CAN FD and Synergy SSP continuity.

FAQ
What is the maximum operating frequency of the R7FS5D97C3A01CFP#BA0?
The R7FS5D97C3A01CFP#BA0 operates at a maximum CPU frequency of 240 MHz using its integrated PLL. This frequency is achievable under specified voltage (3.0–3.6 V) and temperature (−40°C to +85°C) conditions, with proper clock tree configuration and external crystal (e.g., 12 MHz XTAL) as reference. The R7FS5D97C3A01CFP#BA0 maintains timing integrity across all peripherals at this rate when configured per Renesas' clock distribution guidelines.
Does the R7FS5D97C3A01CFP#BA0 support CAN FD, and what data rates are achievable?
Yes, the R7FS5D97C3A01CFP#BA0 integrates a CAN FD controller compliant with ISO 11898-1:2015. It supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps, with payload lengths up to 64 bytes. These capabilities are confirmed in the S5D9 User's Manual Rev.1.40 and require proper termination and transceiver selection (e.g., TJA1057) to achieve full specification performance in the R7FS5D97C3A01CFP#BA0 design.
What security features are implemented in hardware on the R7FS5D97C3A01CFP#BA0?
The R7FS5D97C3A01CFP#BA0 includes dedicated hardware accelerators for AES-128/256 encryption/decryption, SHA-256 hashing, and a NIST SP 800-90B-compliant TRNG. It also supports ECDSA-P256 signature verification and secure boot with immutable root-of-trust. These functions operate independently of the CPU core, ensuring deterministic latency and resistance to software-based side-channel attacks - all documented for the R7FS5D97C3A01CFP#BA0 in Renesas' S5D9 Security Reference Manual.
Is the R7FS5D97C3A01CFP#BA0 pin-compatible with other S5D9 group members?
The R7FS5D97C3A01CFP#BA0 shares the same 176-pin LQFP package and pin assignment with other S5D9 variants in the "CFP" suffix family (e.g., R7FS5D97E3A01CFP#BA0), including identical power, clock, reset, and peripheral pin mappings. However, pin compatibility does not extend to S5D9 devices in different packages (e.g., BGA) or with differing suffixes (e.g., "CBG"), as those reflect distinct pinouts - verified in the R7FS5D97C3A01CFP#BA0 Pin Assignment table (Section 1.6, S5D9 User's Manual Rev.1.40).
Which software development ecosystem supports the R7FS5D97C3A01CFP#BA0?
The R7FS5D97C3A01CFP#BA0 is fully supported by the Renesas Synergy Software Package (SSP) v3.x, including certified HAL drivers, middleware (USB Host/Device, lwIP, FATFS), and the e2 studio IDE with Synergy Configuration Tool. It is also compatible with Arm Keil MDK and IAR Embedded Workbench via CMSIS-Pack. All BSP and driver validation for the R7FS5D97C3A01CFP#BA0 is performed against SSP v3.6.0 and later releases per Renesas' official release notes.
