Product details
Overview
R7FS5D37A3A01CFP#AA0 from Renesas Electronics is a high-integration Arm Cortex-M4 microcontroller operating at 120 MHz with 512-KB code flash, 256-KB SRAM, and dual CAN interfaces. It integrates USB 2.0 Full-Speed with on-chip transceiver, SDHI ×2, QSPI, CTSU for capacitive touch, and hardware crypto engine SCE7 supporting AES-256, RSA, and SHA256 - deployed in industrial HMI and automotive body control modules requiring functional safety and secure firmware updates.
For engineers reviewing the R7FS5D37A3A01CFP#AA0 datasheet, R7FS5D37A3A01CFP#AA0 pinout, R7FS5D37A3A01CFP#AA0 application, or R7FS5D37A3A01CFP#AA0 equivalent, key selection considerations include its -40°C to +105°C LQFP-100 package, dual CAN 2.0B compliance, ECC-protected SRAM, and integrated sampling rate converter (SRC) for audio preprocessing in connected edge devices.
Technical Context
This MCU implements an Armv7E-M architecture with single-precision FPU and DSP extensions, enabling deterministic real-time signal processing in motor control and audio applications. Its memory subsystem includes 512-KB zero-wait-state flash, 8-KB data flash rated for 125,000 erase/write cycles, and 256-KB SRAM split into 32-KB ECC-protected and 224-KB parity-checked regions.
The peripheral set is optimized for system-level integration: dual CAN controllers support mailbox-based message handling up to 32 mailboxes each; two SDHI modules enable redundant card hosting; and the Event Link Controller (ELC) enables direct peripheral-to-peripheral triggering without CPU intervention - critical for low-latency sensor fusion and safety-critical timing chains.
Key Specifications

| Sampling Rate Converter (SRC) | Resamples stereo/mono audio data between 8–96 kHz domains in hardware - offloads CPU from real-time audio format adaptation in voice UI or codec bridging applications. |
| Port Output Enable for GPT (POEG) | Hardware-gated PWM outputs prevent shoot-through during BLDC motor startup/shutdown - eliminates need for external gate drivers or software dead-time insertion. |
| Secure Crypto Engine 7 (SCE7) | Accelerates AES-256 encryption/decryption at >10 MB/s and ECDSA signature generation in <5 ms - enables secure firmware authentication and encrypted field data transmission without performance penalty. |
