Product details
Overview
R7FA8T1AFECFP#BA0 from Renesas is a high-performance 32-bit Arm® Cortex®-M85 microcontroller operating at up to 480 MHz, featuring 1 MB code flash, 12 KB data flash, and 1 MB SRAM with ECC/parity support. It integrates Ethernet MAC, USB 2.0 Full-Speed, dual CAN FD, dual SDHI, I3C, and advanced analog peripherals including dual 12-bit ADCs/DACs and ACMPHS. Designed for industrial automation and secure edge gateways requiring real-time control, connectivity, and hardware-based security.
For engineers reviewing the R7FA8T1AFECFP#BA0 datasheet, R7FA8T1AFECFP#BA0 pinout, R7FA8T1AFECFP#BA0 application, or R7FA8T1AFECFP#BA0 equivalent, key selection considerations include its 100-pin LQFP package, -40°C to +125°C junction temperature rating, TrustZone-enabled secure boot, RSIP-E51A cryptographic acceleration, and dual-channel CAN FD with 4 Tx/16 Rx buffers per channel.
Technical Context
The R7FA8T1AFECFP#BA0 implements Armv8.1-M architecture with Helium™ M-profile Vector Extension (MVE), supporting integer and single-precision floating-point SIMD operations for motor control and signal processing. Its dual-bank flash supports background programming and SWAP operations, enabling seamless firmware updates without halting execution.
Security is enforced via Arm TrustZone partitioning-configurable into two or four secure/non-secure regions for code flash, two for data flash, and two for SRAM-combined with Renesas Secure IP (RSIP-E51A) for AES/RSA/ECC acceleration, 128-bit unique ID, and tamper-resistant key management. Peripheral attribution is individually configurable as secure or non-secure.
