Lattice GAL22V10D-15LD/883: A High-Reliability 22V10 PLD for Mission-Critical Systems

In the demanding world of military and aerospace technology, where failure is not an option, electronic components must operate flawlessly under extreme conditions. The Lattice GAL22V10D-15LD/883 stands as a paragon of such reliability, representing a specialized class of programmable logic devices (PLDs) engineered for the most critical applications.

This device is a militarized, high-reliability version of the industry-standard 22V10 PLD architecture. Its core function is to replace multiple simple logic gates and flip-flops with a single, reconfigurable chip, thereby significantly reducing board space, component count, and overall system weight—a critical factor in aerospace design. The "22V10" denotes 22 inputs and 10 outputs, with each output macrocell being independently configurable for combinatorial or registered logic.

The "883" suffix is the key differentiator, signifying that the device is processed and screened in strict compliance with the U.S. Department of Defense's MIL-PRF-38535 standard. This rigorous certification process includes:

Extended Temperature Range Operation: Certified performance from -55°C to +125°C.

Stringent Quality Assurance: Each lot undergoes exhaustive testing for DC and AC parameters, including burn-in and temperature cycling.

Controlled Manufacturing: Fabrication in a certified QML (Qualified Manufacturers List) facility ensures traceability and process control far exceeding commercial-grade parts.

The GAL22V10D-15LD/883 is fabricated in CMOS technology, offering low power consumption, which is vital for power-sensitive avionics and portable military systems. The "-15" in its part number indicates a maximum pin-to-pin propagation delay of 15 nanoseconds, providing sufficient speed for a vast array of control and interface logic functions, such as state machine control, address decoding, and bus interfacing.

Its non-volatile E²CMOS technology ensures that the programmed logic pattern is retained even when power is removed, eliminating the need for external configuration memory and enhancing system security and simplicity. The device is reprogrammable, offering design flexibility during prototyping and validation phases.

Applications for this robust PLD are found in environments where commercial-grade components are inadequate. These include:

Satellite subsystems and flight control computers.

Radar and sonar signal processing equipment.

Military communications and encryption hardware.

Test and measurement equipment designed for field deployment.

ICGOOODFIND: The Lattice GAL22V10D-15LD/883 remains a cornerstone component for engineers designing legacy and new systems for military and aerospace applications. Its proven reliability, strict compliance with military standards, and integration capabilities make it an indispensable solution for reducing risk and ensuring long-term performance in the harshest operating environments.
