Lattice GAL22V10D-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 critical missions. The Lattice GAL22V10D-10LD/883 stands as a premier solution, engineered from the ground up to meet the stringent requirements of these high-reliability applications.
This device is a member of the iconic 22V10 family of Programmable Logic Devices (PLDs), a workhorse architecture known for its versatility in implementing complex combinational and sequential logic. The "GAL" prefix signifies that it is a Generic Array Logic device manufactured with advanced CMOS technology, offering a superior blend of high speed and low power consumption. The "883" suffix is crucial, denoting that the component is processed and screened in full compliance with the MIL-PRF-38535 Class V qualified manufacturer list (QML). This certification is a hallmark of quality and reliability, ensuring performance across the military temperature range of -55°C to +125°C.
The GAL22V10D-10LD/883 provides a highly flexible logic structure. It features 22 inputs and 10 output logic macrocells. Each output macrocell can be individually configured by the user, offering programmable output polarity (active high or active low) and selectable registered or combinatorial operation. This programmability allows a single device to replace dozens of standard discrete logic ICs, significantly reducing board space, weight, and power consumption—all critical factors in aerospace and military system design.
A key differentiator for the -10LD/883 variant is its guaranteed 10ns maximum propagation delay. This high speed enables the device to perform in timing-critical applications, ensuring signal integrity and system synchronization even in the most challenging scenarios. Furthermore, its electrically erasable (E²) CMOS technology allows for complete reprogrammability. This is a significant advantage for prototyping, field upgrades, and design iterations, as it eliminates the need for costly and time-consuming UV erasure required by older technologies.
The device's packaging, a 28-lead ceramic dual in-line package (DIP) with lead (LD), is robust and designed for reliability in harsh environments. The ceramic material offers excellent thermal performance and hermeticity, protecting the silicon die from moisture and contaminants.
ICGOOODFIND: The Lattice GAL22V10D-10LD/883 remains a cornerstone for legacy and new designs in sectors where failure is not an option. Its combination of MIL-PRF-38535 QML certification, high-speed performance, reprogrammability, and the proven 22V10 architecture makes it an indispensable component for engineers designing mission-critical systems for military, aerospace, and other high-reliability industries.
