Lattice GAL22V10C-10LD/883: A High-Reliability 22V10 PLD for Military and Aerospace Applications
In the demanding world of military and aerospace technology, electronic components are required to operate flawlessly under extreme conditions, including wide temperature ranges, intense vibration, and high levels of radiation. Standard commercial-grade parts are unsuitable for these mission-critical roles. The Lattice GAL22V10C-10LD/883 stands as a pinnacle of reliability, engineered specifically to meet the stringent requirements of these applications.
This device is a member of the proven Generic Array Logic (GAL) family, a highly popular type of Programmable Logic Device (PLD). The "22V10" designation indicates a versatile architecture with 22 inputs and 10 outputs, each of which can be configured as either an input or an output. This flexibility allows designers to consolidate numerous discrete logic ICs into a single, programmable chip, significantly reducing board space, weight, and system complexity—a critical advantage in size-constrained aerospace platforms.
The GAL22V10C-10LD/883 differentiates itself from its commercial counterparts through its "883" suffix. This denotes compliance with the MIL-PRF-38535 qualified manufacturer list (QML) and MIL-STD-883 certification standards. This rigorous certification process ensures the device is manufactured and tested to the highest levels of quality and reliability. Key features of this military-grade processing include:
Extended Temperature Range: Guaranteed operation from -55°C to +125°C.
Robust Packaging: Housed in a hermetically sealed ceramic Dual-In-Line (DIP) package, protecting the silicon die from moisture and contaminants.
Stringent Screening: Every device undergoes exhaustive electrical and environmental testing, including burn-in, temperature cycling, and hermeticity tests, to eliminate early-life failures and ensure performance under stress.
With a speed grade of "-10", the device guarantees a maximum propagation delay of 10ns, providing sufficient speed for a vast array of interface logic, state machine, and address decoding functions common in legacy military systems. Its electrically erasable (EECMOS) technology allows for rapid design iteration and re-programmability, a valuable feature during prototyping and system upgrades, even though the final deployed units are often one-time programmed for maximum security and data retention.
The primary application domains for the GAL22V10C-10LD/883 are in legacy systems and new designs where absolute reliability is non-negotiable. This includes:
Avionics systems in aircraft and satellites
Mission computers and navigation equipment
Radar and sonar signal processing interfaces
Military communications infrastructure
For engineers tasked with maintaining, upgrading, or designing new systems for extreme environments, the GAL22V10C-10LD/883 offers a trusted, programmable logic solution. It bridges the gap between modern, non-rad-hard FPGAs and obsolete discrete logic, providing a proven, low-risk path to implementing complex digital logic.
ICGOODFIND: The Lattice GAL22V10C-10LD/883 remains a cornerstone component for high-reliability digital design. Its MIL-STD-883 certification, hermetic ceramic packaging, and proven 22V10 architecture make it an indispensable solution for sustaining and modernizing critical military and aerospace systems that demand longevity, performance, and unwavering reliability under the most severe operating conditions.
