ISPGAL22V10AV-75LJ

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LJ is a Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide electrically erasable programmability within the GAL22V10 architecture. The device features a maximum propagation delay of 7.5 ns and operates in a 28-pin Plastic Quad Flat Package (PQCC28), also identified as LCC-28. It contains ten output logic macrocells designed for complex logic applications, offering reconfigurable logic capabilities with high-speed electrical erase functions.

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'AV' against official Lattice documentation to confirm voltage levels and temperature ranges, as generic listings may omit these details. Confirm package integrity for the PQCC28/LCC-28 form factor. Check current availability status, as older SPLD families may have limited supply chains or end-of-life implications requiring alternative sourcing strategies.

Programmable Logic Device Pld Selection Notes

Select this component when a drop-in replacement for legacy bipolar or UVCMOS 22V10 devices is required but with lower power consumption and reprogrammability. Ensure the design accommodates the 28-pin LCC-28 footprint. Verify that the 7.5 ns timing meets the system's clock frequency requirements, which are lower than the 4 ns variants available in the same family.

Programmable Logic Device Pld Part Context

This part belongs to the ispGAL22LV10 and GAL22V10 families from Lattice Semiconductor. These devices represent an evolution of the classic PAL/GAL logic structures, integrating EEPROM cells into CMOS processes. They serve as direct functional replacements for older discrete logic solutions while offering the advantage of field reconfiguration without UV erasure equipment.

Programmable Logic Device Pld Replacement Considerations

Direct functional substitutes include other GAL22V10 variants such as GAL22V10D-25LJ or ISPGAL22V10AV-75LI, provided the package type and speed grade match the design constraints. Verify pin compatibility and electrical parameters before substitution.
