Overview
R7FS5D37A3A01CFP#BA0 from Renesas Electronics is a high-integration Arm Cortex-M4 microcontroller operating at 120 MHz with FPU, 512-KB code flash, 256-KB SRAM, and dual CAN interfaces. It integrates CTSU for capacitive touch, USB 2.0 Full-Speed with on-chip transceiver, SDHI ×2, QSPI, and advanced analog peripherals including dual 12-bit ADCs with sample-and-hold and dual 12-bit DACs. It targets industrial HMI, motor control, and secure embedded gateways requiring functional safety and cryptographic acceleration.
For engineers reviewing the R7FS5D37A3A01CFP#BA0 datasheet, R7FS5D37A3A01CFP#BA0 pinout, R7FS5D37A3A01CFP#BA0 application, or R7FS5D37A3A01CFP#BA0 equivalent, key selection considerations include its -40°C to +105°C temperature grade, 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), dual CAN 2.0B compliance, SCE7 crypto engine supporting AES-256/SHA256/RSA/ECC, and integrated RTC with VBATT backup.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling deterministic real-time signal processing. Its memory subsystem includes ECC-protected SRAM (32 KB), parity-checked SRAM (224 KB), 8-KB data flash rated for 125,000 erase/write cycles, and Memory Mirror Function (MMF) for flexible firmware load/link address decoupling.
The peripheral set supports concurrent high-bandwidth I/O: dual SDHI controllers for redundant card slots, QSPI for external XIP flash, SSIE with 32-stage FIFOs for multi-channel audio, and ELC-driven autonomous peripheral chaining-eliminating CPU intervention for time-critical event sequences such as PWM-triggered ADC sampling or CAN-to-DMA transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D37A3A01CLJ | LGA-100 package (7 mm × 7 mm, 0.65 mm pitch); identical electrical specs and feature set. | Better suited for high-density PCBs where footprint area is constrained; requires different reflow profile due to bottom-termination LGA. | Select when board space is critical and assembly process supports LGA; pinout is identical but land pattern differs. |
| R7FS5D37A2A01CLJ | Same LGA-100 package but rated for -40°C to +85°C; otherwise identical peripherals and memory. | Targeted at commercial/indoor applications without extended temperature requirements; lower cost due to reduced qualification testing. | Choose for cost-sensitive indoor equipment where ambient temperature stays below 85°C; not suitable for under-hood or outdoor deployments. |
Compared with R7FS5D37A3A01CFP#BA0, the LGA variants offer superior thermal dissipation and smaller footprint but require more complex PCB layout and assembly; the -85°C version reduces thermal margin and qualification scope, trading environmental robustness for bill-of-materials savings in benign environments.

FAQ
What is the maximum operating frequency and core architecture of the R7FS5D37A3A01CFP#BA0?
The R7FS5D37A3A01CFP#BA0 features an Arm Cortex-M4 core with Floating Point Unit (FPU) operating at a maximum frequency of 120 MHz. It implements the Armv7E-M architecture with DSP instruction extensions, enabling high-performance real-time signal processing. This specification is confirmed in the official Renesas datasheet R01DS0328EU0120 Rev.1.20, Section 1.1 and Table 1.1. The R7FS5D37A3A01CFP#BA0 delivers deterministic execution for motor control, sensor fusion, and audio processing tasks.
Does the R7FS5D37A3A01CFP#BA0 support CAN FD or only classical CAN 2.0?
The R7FS5D37A3A01CFP#BA0 supports only classical CAN 2.0A/B (ISO 11898-1), not CAN FD. Its dual CAN modules provide 32 configurable mailboxes, standard (11-bit) and extended (29-bit) identifier support, and bit rates up to 1 Mbps. This is explicitly stated in Section 1.8 of the R01DS0328EU0120 datasheet. For CAN FD functionality, designers must consider higher-tier Synergy S7 series MCUs. The R7FS5D37A3A01CFP#BA0 remains fully compatible with legacy CAN networks in industrial automation and automotive body systems.
What package type and pin count does the R7FS5D37A3A01CFP#BA0 use?
The R7FS5D37A3A01CFP#BA0 uses a 100-pin LQFP package (PLQP0100KB-B) with 14 mm × 14 mm body size and 0.5 mm pitch. This is confirmed in Table 1.14 (Product List) and Figure 1.2 (Part Numbering Scheme) of the R01DS0328EU0120 datasheet. The "FP" suffix in the part number directly denotes LQFP-100. The R7FS5D37A3A01CFP#BA0 provides 67 CMOS I/O pins, 14 of which are 5 V tolerant, making it suitable for mixed-voltage industrial interfaces.
How does the Memory Mirror Function (MMF) benefit firmware development for the R7FS5D37A3A01CFP#BA0?
The Memory Mirror Function (MMF) in the R7FS5D37A3A01CFP#BA0 maps the physical flash load address to a virtual link address in unused 23-bit memory space, allowing application code to be linked and executed from a fixed address regardless of its actual flash location. As described in Section 1.2 and Table 1.2 of R01DS0328EU0120, this eliminates manual relocation code and simplifies A/B firmware swapping. Developers can update R7FS5D37A3A01CFP#BA0 firmware without modifying linker scripts or runtime address calculations.
What security features are implemented in the Secure Crypto Engine 7 (SCE7) of the R7FS5D37A3A01CFP#BA0?
The R7FS5D37A3A01CFP#BA0 integrates SCE7 supporting AES-128/192/256, 3DES, ARC4, SHA1/224/256, MD5, GHASH, RSA/DSA/ECC, and a True Random Number Generator (TRNG). These are detailed in Table 1.12 and Section 1.12 of R01DS0328EU0120. SCE7 operates independently of the CPU, protecting keys in secure memory and accelerating cryptographic operations by >10× versus software-only implementations - critical for secure boot, firmware signing, and TLS offload in the R7FS5D37A3A01CFP#BA0.
