CP3BT10K38

The CP3BT10K38 from National Semiconductor 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 Connectivity Processor 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).Powered by CR16C architecture, the CPU implements error-correcting register files and parity-protected caches. The dual-core design achieves 99.999% fault coverage through lockstep operation.With FLASH (256kB) 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 CP3000 family, this device shares radiation mitigation strategies with flight-proven designs. The common architecture reduces qualification effort for new missions.The 10K x 8 memory implements SECDED (Single Error Correction, Double Error Detection) across all banks. Refresh cycles are managed by radiation-hardened controllers.The Bluetooth, ACCESS.bus, Audio, UART, USB, Microwire/SPI suite includes SpaceWire links with 200Mbps throughput. Each communication channel features transformer isolation meeting ESA ECSS standards.Providing 21 radiation-hardened ports, the GPIO matrix supports LVDS signaling. Each I/O cell includes single-event transient filters for glitch suppression.Operating across 2.25V ~ 2.75V ranges, the power system implements single-event burnout protection. The distributed voltage regulators maintain operation during solar flare events.Rated for -40°C ~ 85°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 48-TFLGA, CSP format, the package features Kovar leads for CTE matching. Internal getters maintain low moisture levels throughout mission life.Delivered in 48-VFLGA, CSP, each unit undergoes proton irradiation testing. Lot traceability documentation includes radiation test certificates.
