Product details
Overview
R7FA6M5AH3CFP#AA0 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 2 MB dual-bank code flash with background/swap operation, 8 KB data flash, and 512 KB SRAM with parity/ECC. It integrates Ethernet MAC, USB 2.0 High-Speed, dual CAN FD, SDHI, QSPI/OSPI, and Secure Crypto Engine 9 with TrustZone for industrial gateway and secure edge node applications.
For engineers reviewing the R7FA6M5AH3CFP#AA0 datasheet, R7FA6M5AH3CFP#AA0 pinout, R7FA6M5AH3CFP#AA0 application, or R7FA6M5AH3CFP#AA0 equivalent, key selection considerations include its -40°C to +105°C temperature rating, 100-pin LQFP package, dual CAN FD support, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet MAC with RMII interface.
Technical Context
The R7FA6M5AH3CFP#AA0 implements Armv8-M with TrustZone security extension, enabling strict isolation between secure and non-secure firmware execution environments. Its memory subsystem includes dual-bank flash supporting live firmware updates without interruption and ECC-protected SRAM for functional safety compliance.
Connectivity is centered on deterministic real-time interfaces: two CAN FD controllers (16 TX/16 RX buffers each), Ethernet MAC with DMA coupling to EDMAC, USBHS/USBFS dual-role capability, and QSPI/OSPI for external XIP flash. The analog subsystem provides two 12-bit ADCs (5 Msps interleaved) and two 12-bit DACs with shared input channels and on-die temperature sensor.
