Product details
Nuvoton Technology Corporation's W79E2051RAKG delivers military-grade reliability in Embedded - Microcontrollers, developed for aerospace and defense applications where radiation tolerance and mission longevity are paramount.The 8051 core incorporates triple modular redundancy for SEU mitigation, achieving >99% single-event upset immunity in orbital radiation environments.A 8-Bit architecture with parity-protected data paths prevents silent data corruption, meeting MIL-STD-883G requirements for spaceborne electronics.When operating at 24MHz, the microcontroller maintains timing accuracy within 0.01% despite temperature variations from -55 C to 125 C, critical for navigation systems.The 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, LED, LVD, POR, PWM, WDT include radiation-hardened timers and watchdog circuits that automatically recover from single-event functional interrupts within 10 s.With 17 MIL-STD-1553-compatible interfaces, the device can serve as a remote terminal in distributed avionics architectures without external transceivers.2KB (2K 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.128 x 8 of rad-hard non-volatile storage maintains configuration data through 10,000 write cycles, sufficient for the spacecraft's entire mission duration.256 x 8 of scrubable memory prevents accumulation of single-event upsets, maintaining data integrity during extended missions in high-radiation orbits.The 2.4V ~ 5.5V range supports operation from unregulated spacecraft power buses with 100mV ripple, eliminating need for additional regulation stages.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.Through Hole packaging uses AuSn die attach for superior thermal conductivity in vacuum environments, preventing die delamination during thermal transients.The 20-DIP Module format provides hermetic sealing against moisture ingress, meeting MIL-PRF-38534 Class K requirements for high-reliability applications.
