Product details
Overview
R7FA8T1AHECBD#UC0 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 connectivity, secure firmware updates, and deterministic motor control.
For engineers reviewing the R7FA8T1AHECBD#UC0 datasheet, R7FA8T1AHECBD#UC0 pinout, R7FA8T1AHECBD#UC0 application, or R7FA8T1AHECBD#UC0 equivalent, key selection criteria include its 224-pin BGA package, -40°C to +125°C junction temperature rating, TrustZone-enabled secure boot, dual CAN FD channels for automotive diagnostics, and Ethernet MAC with DMA for time-sensitive networking.
Technical Context
The R7FA8T1AHECBD#UC0 implements Armv8.1-M architecture with M-profile Vector Extension (MVE) for DSP-intensive workloads and includes two independent SysTick timers (Secure/Non-secure) driven by CPUCLK or MOCO/8. Its memory subsystem integrates 2 MB code flash supporting background operation and SWAP, 12 KB data flash rated for 100,000 P/E cycles, and 1 MB SRAM split into 128 KB TCM (ECC), 512 KB parity, and 384 KB ECC regions.
Connectivity is centered on hardware-accelerated interfaces: dual CAN FD controllers (4 TX/16 RX buffers per channel), Ethernet MAC/DMA compliant with IEEE 802.3, USBFS host/device mode with internal transceiver and 10-pipe buffer, and dual SDHI supporting SDXC/eMMC 4.51. Security relies on RSIP-E51A (AES/RSA/ECC/HASH), 128-bit unique ID, tamper detection, and Arm TrustZone partitioning of flash, SRAM, and peripherals.
