GAL22LV10ZD-25QJ

Programmable Logic Device Pld Overview

The GAL22LV10ZD-25QJ is a high-performance Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor Corporation. It belongs to the ispGAL22LV10 family, which utilizes In-System Programmability (ISP) and operates at a 3.3-volt supply voltage. The device features 10 macrocells and is housed in a 28-pin PLCC package. It offers a maximum propagation delay of 25 nanoseconds, providing significant performance improvements over previous generations while maintaining compatibility with standard 22V10 logic functions.

Programmable Logic Device Pld Feature Summary

• Utilizes advanced CMOS technology to achieve lower power consumption compared to traditional bipolar devices
• Features active pull-ups on all pins to ensure stable logic levels during idle states
• Provides full functional, fuse-map, and parametric compatibility with standard bipolar and UVCMOS 22V10 devices

Programmable Logic Device Pld Applications

• DMA control systems requiring fast response times
• State machine control for complex digital sequences
• High-speed graphics processing interfaces
• Standard logic speed upgrades in legacy designs

Programmable Logic Device Pld Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm that the specific suffix matches the required voltage and package specifications. Check for recent Product Change Notifications (PCNs) regarding marking or packaging updates. Ensure design-in compliance with current environmental regulations if applicable, noting historical RoHS status variations for mature devices.

Programmable Logic Device Pld Selection Notes

Select this component when 3.3-volt operation is required instead of the standard 5-volt GAL22V10. Choose this model for applications needing In-System Programmability to simplify manufacturing and field updates. Consider this device for designs requiring faster switching speeds than older GAL variants while maintaining pin-out compatibility with existing 22V10 footprints.

Programmable Logic Device Pld Part Context

This device is part of the ispGAL22LV10 family, representing an evolution of the classic GAL22V10 architecture. It integrates Lattice's ISP technology, allowing designers to modify logic configurations after assembly. This family bridges the gap between fixed-function logic and more complex FPGAs, offering a cost-effective solution for moderate complexity logic applications in industrial and consumer electronics.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes include other members of the GAL22V10 series such as GAL22V10D-25QJ for 5-volt applications. For equivalent 3.3-volt performance, consider the GAL22LV10D-25QJ. Verify package compatibility and voltage tolerance before swapping components in existing hardware designs.
