ATXMEGA384D3-CCU
Atmel
Product details
Atmel's ATXMEGA384D3-CCU delivers military-grade reliability in Embedded - Microcontrollers, developed for aerospace and defense applications where radiation tolerance and mission longevity are paramount.The AVR core incorporates triple modular redundancy for SEU mitigation, achieving >99% single-event upset immunity in orbital radiation environments.A 8/16-Bit architecture with parity-protected data paths prevents silent data corruption, meeting MIL-STD-883G requirements for spaceborne electronics.When operating at 32MHz, the microcontroller maintains timing accuracy within 0.01% despite temperature variations from -55 C to 125 C, critical for navigation systems.The I²C, IrDA, SPI, UART/USART interfaces implement Manchester encoding for noise-immune data transmission, ensuring reliable communication in high-EMI environments like radar installations.Brown-out Detect/Reset, DMA, POR, PWM, WDT include radiation-hardened timers and watchdog circuits that automatically recover from single-event functional interrupts within 10 s.With 50 MIL-STD-1553-compatible interfaces, the device can serve as a remote terminal in distributed avionics architectures without external transceivers.384KB (384K x 8) of TMR-protected storage accommodates flight control algorithms with full error detection and correction capabilities.The FLASH implementation uses SONOS technology that withstands 300krad total ionizing dose, exceeding space qualification requirements.4K x 8 of rad-hard non-volatile storage maintains configuration data through 10,000 write cycles, sufficient for the spacecraft's entire mission duration.32K x 8 of scrubable memory prevents accumulation of single-event upsets, maintaining data integrity during extended missions in high-radiation orbits.The 1.6V ~ 3.6V range supports operation from unregulated spacecraft power buses with 100mV ripple, eliminating need for additional regulation stages.Precision A/D 16x12b maintain 12-bit accuracy during solar flare events, providing reliable telemetry data even during peak radiation periods.The Internal clock source incorporates automatic frequency compensation that maintains <1ppm/ C drift across the military temperature range.Qualified for -40°C ~ 85°C (TA), the device operates reliably in exoatmospheric conditions where thermal cycling extremes exceed commercial specifications.
