Product details
The BT817AQ-R from Bridgetek Pte Ltd. establishes a new paradigm in Embedded - Microcontrollers - Application Specific, crafted for aerospace and defense systems. This radiation-hardened microcontroller delivers fault-tolerant computing with SEU (Single Event Upset) mitigation techniques, ensuring reliable operation in space environments.Designed for Human Machine Interfaces (HMI) deployments, the device incorporates triple-modular redundancy for critical processing paths. Its MIL-STD-883 qualified design withstands total ionizing dose effects up to 300krad(Si).With FLASH configuration, the memory subsystem employs scrubbing algorithms for SEU recovery. The EDAC-protected flash maintains data integrity even under heavy particle bombardment.As part of the BT81X family, this device shares radiation mitigation strategies with flight-proven designs. The common architecture reduces qualification effort for new missions.The LED, LCD, QSPI, SPI suite includes SpaceWire links with 200Mbps throughput. Each communication channel features transformer isolation meeting ESA ECSS standards.Providing 4 radiation-hardened ports, the GPIO matrix supports LVDS signaling. Each I/O cell includes single-event transient filters for glitch suppression.Operating across 3V ~ 3.6V ranges, the power system implements single-event burnout protection. The distributed voltage regulators maintain operation during solar flare events.Rated for -40°C ~ 105°C (TA) extremes, the package utilizes ceramic substrates with gold metallization. Thermal vias maintain junction temperatures in vacuum conditions.The Surface Mount configuration supports hermetic sealing processes. Die attachment uses AuSi eutectic bonding for mechanical stability under vibration.Available in 64-WFQFN Exposed Pad format, the package features Kovar leads for CTE matching. Internal getters maintain low moisture levels throughout mission life.Delivered in 64-VQFN (9x9), each unit undergoes proton irradiation testing. Lot traceability documentation includes radiation test certificates.
