Product details
Overview
R7FA8T1AHECFB#BA0 from Renesas is a high-performance 480 MHz Arm® Cortex®-M85 microcontroller with Helium™, featuring 2 MB dual-bank code flash, 12 KB data flash, 1 MB SRAM (with ECC/parity), Ethernet MAC, USB 2.0 Full-Speed, dual CAN FD, SDHI, I3C, and integrated RSIP-E51A security IP. It targets industrial automation gateways requiring real-time control, secure connectivity, and deterministic timing.
For engineers reviewing the R7FA8T1AHECFB#BA0 datasheet, R7FA8T1AHECFB#BA0 pinout, R7FA8T1AHECFB#BA0 application, or R7FA8T1AHECFB#BA0 equivalent, key selection criteria include its 144-pin LQFP package, -40°C to +125°C operating range, TrustZone-enabled secure boot, dual CAN FD for automotive diagnostics, and Ethernet MAC with DMA for protocol stack offload.
Technical Context
The R7FA8T1AHECFB#BA0 implements Armv8.1-M architecture with M-profile Vector Extension (MVE) and floating-point unit, enabling efficient signal processing in motor control and sensor fusion. Its dual-bank flash supports background programming and SWAP operations for zero-downtime firmware updates.
Security is enforced via Arm TrustZone partitioning (up to four flash regions, two SRAM/data flash regions), hardware-accelerated AES/RSA/ECC in RSIP-E51A, tamper detection, and secure pin multiplexing. The ELC and DTC enable autonomous peripheral coordination without CPU intervention.
