Product details
Overview
R7FA6M5BF3CFB#BA0 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 1 MB code flash, 8 KB data flash, and 512 KB SRAM with ECC/parity. It integrates dual CAN FD, USB 2.0 High-Speed, Ethernet MAC, QSPI/OSPI, SDHI, and Secure Crypto Engine (SCE9) with TrustZone for industrial gateway and secure edge node applications.
For engineers reviewing the R7FA6M5BF3CFB#BA0 datasheet, R7FA6M5BF3CFB#BA0 pinout, R7FA6M5BF3CFB#BA0 application, or R7FA6M5BF3CFB#BA0 equivalent, key selection criteria include its -40°C to +105°C operation, 144-pin LQFP package, dual-bank flash support, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet+USBHS+CAN FD connectivity for deterministic real-time control.
Technical Context
The R7FA6M5BF3CFB#BA0 implements Armv8-M architecture with TrustZone-enforced secure/non-secure worlds, supporting concurrent execution of safety-critical and application firmware. Its memory subsystem includes dual-bank flash enabling background programming and SWAP operations without CPU interruption, plus 512 KB SRAM with configurable ECC or parity protection per region.
Connectivity is centered on deterministic real-time I/O: two CAN FD controllers (16 TX/RX buffers each), USB 2.0 High-Speed host/device with internal transceiver and 10-pipe FIFO, IEEE 802.3-compliant Ethernet MAC with DMA coupling, and QSPI/OSPI interfaces for external XIP-capable flash. The SCE9 crypto engine offloads AES-128/256, RSA-2048/4096, ECC P-256/P-384, and SHA224/256 operations.
