Product details
Infineon Technologies's TT21402-44LQI28 delivers military-grade reliability in Embedded - Microcontrollers, developed for aerospace and defense applications where radiation tolerance and mission longevity are paramount.The ARM® Cortex® core incorporates triple modular redundancy for SEU mitigation, achieving >99% single-event upset immunity in orbital radiation environments.A 32-Bit Single-Core architecture with parity-protected data paths prevents silent data corruption, meeting MIL-STD-883G requirements for spaceborne electronics.When operating at 500kHz, the microcontroller maintains timing accuracy within 0.01% despite temperature variations from -55 C to 125 C, critical for navigation systems.The I²C, SPI interfaces implement Manchester encoding for noise-immune data transmission, ensuring reliable communication in high-EMI environments like radar installations.With 28 MIL-STD-1553-compatible interfaces, the device can serve as a remote terminal in distributed avionics architectures without external transceivers.The 1.71V ~ 5.5V range supports operation from unregulated spacecraft power buses with 100mV ripple, eliminating need for additional regulation stages.Surface Mount packaging uses AuSn die attach for superior thermal conductivity in vacuum environments, preventing die delamination during thermal transients.The 44-UFQFN Exposed Pad format provides hermetic sealing against moisture ingress, meeting MIL-PRF-38534 Class K requirements for high-reliability applications.Available in 44-QFN (5x5), the microcontroller undergoes rigorous screening including burn-in and 100% electrical testing at temperature extremes.
