Product details
The AT91SAM9G46-CU from Microchip Technology delivers military-grade reliability in the Embedded - Microprocessors category, hardened for aerospace and defense applications. This radiation-hardened microprocessor combines triple-modular redundancy with error-correcting architectures, meeting MIL-STD-883 requirements for mission-critical systems.Featuring a ARM926EJ-S radiation-hardened core, the processor implements lockstep execution with cycle-by-cycle comparison for fault detection.The 1 Core, 32-Bit configuration includes redundant execution units for single-event upset mitigation in space applications.Operating at 400MHz, the device meets the real-time processing requirements of spacecraft attitude control systems.LPDDR, LPSDR, DDR2, SDR, SRAM memory interfaces incorporate SECDED ECC protection for single-event upset mitigation in orbit.No display controllers include radiation-hardened frame buffers for critical spacecraft displays.The LCD, Touchscreen interfaces implement MIL-STD-1553 protocol support for aerospace databuses.10/100Mbps implementations include space-grade PHYs with enhanced EMI characteristics for spacecraft applications.The USB 2.0 (3) interfaces meet MIL-STD-1275 requirements for military vehicle power environments.1.8V, 3.3V tolerant I/Os withstand transient voltage spikes common in military electrical systems.Qualified for -40°C ~ 85°C (TA) operation, the processor functions in extreme space and high-altitude environments.The 324-TFBGA package implements hermetic sealing for protection against moisture and contaminants.Available in 324-TFBGA (15x15), the device supports military-grade PCB assembly processes.
