Product details
Renesas Electronics America Inc's UPD78F0889AGKA-GAJ-G delivers military-grade reliability in Embedded - Microcontrollers, developed for aerospace and defense applications where radiation tolerance and mission longevity are paramount.The 78K/0 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 20MHz, the microcontroller maintains timing accuracy within 0.01% despite temperature variations from -55 C to 125 C, critical for navigation systems.The 3-Wire SIO, CANbus, I²C, LINbus, UART/USART interfaces implement Manchester encoding for noise-immune data transmission, ensuring reliable communication in high-EMI environments like radar installations.LVD, POR, PWM, WDT include radiation-hardened timers and watchdog circuits that automatically recover from single-event functional interrupts within 10 s.With 55 MIL-STD-1553-compatible interfaces, the device can serve as a remote terminal in distributed avionics architectures without external transceivers.96KB (96K 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 scrubable memory prevents accumulation of single-event upsets, maintaining data integrity during extended missions in high-radiation orbits.The 5V range supports operation from unregulated spacecraft power buses with 100mV ripple, eliminating need for additional regulation stages.Precision A/D 12x10b maintain 12-bit accuracy during solar flare events, providing reliable telemetry data even during peak radiation periods.Qualified for -40°C ~ 85°C (TA), the device operates reliably in exoatmospheric conditions where thermal cycling extremes exceed commercial specifications.
