ISPGAL22V10AV-5LNNI

Programmable Logic Device Pld Overview

The ispGAL22V10AV-5LNNI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, manufactured using low-voltage E2CMOS technology. Designed for 3.3V operation, it features a maximum propagation delay of 5.0ns and a typical standby power consumption under 300µW. The device integrates ten Output Logic Macrocells (OLMCs) with variable product term access, supporting both registered and combinatorial modes. It includes an electronic signature register, IEEE 1149.1 boundary scan testability, and hot-socketing capabilities. The component utilizes a 32-pin Lead-Free QFN package.

Programmable Logic Device Pld Feature Summary

Programmable Logic Device Pld Procurement Notes

This specific part number is officially discontinued as per Product Change Notification #09-10. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Designers must confirm the lead-free packaging status associated with the 'NN' suffix and ensure compatibility with existing board layouts given the 32-pin QFN form factor.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy designs require exact functional compatibility with standard 22V10 devices while operating at 3.3V. The -5 speed grade offers a 5.0ns propagation delay, suitable for moderate-speed logic applications. Consider the 32-pin QFN package constraints for thermal management and PCB footprint requirements during selection.

Programmable Logic Device Pld Part Context

The ispGAL22V10A family represents Lattice's advancement in low-voltage SPLDs, bridging the gap between traditional GAL devices and modern FPGAs. The AV variant specifically targets 3.3V systems, offering pin-to-pin compatibility with older bipolar and UVCMOS 22V10 architectures while providing significantly lower power consumption and higher performance speeds.

Programmable Logic Device Pld Replacement Considerations

Due to the discontinuation status, direct replacements are not available through standard channels. Designers may consider the ispGAL22LV10 series for similar functionality in 3.3V environments or explore generic array logic alternatives that match the 28/32-pin package and macrocell count specifications.
