ISPGAL22V10AV-75LS

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LS is a Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, belonging to the ispGAL22V10 family. It utilizes E2CMOS technology for electrically erasable programmability. The device features 22 input/output pins and 10 macrocells. The suffix '75' indicates a maximum propagation delay of 7.5 ns. The 'A' denotes an industrial temperature range (-40°C to +85°C), while 'LS' specifies a 28-pin Plastic Quad Flatpack (PQFP) surface-mount package. It operates at 5V.

Programmable Logic Device Pld Part Context

The ISPGAL22V10AV-75LS is part of the ispGAL22V10 family, which serves as a drop-in replacement for older GAL22V10 devices. It maintains pinout and functional compatibility with bipolar and UV-erasable CMOS 22V10 devices while offering lower power consumption and electrical reprogrammability. This family bridges the gap between fixed logic gates and more complex CPLDs.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other speed grades within the ispGAL22V10AV series (e.g., ISPGAL22V10AV-10LS) if timing constraints allow. For legacy designs, GAL22V10 equivalents may be functionally compatible but lack electrical reprogrammability. Verify package footprint compatibility when substituting with different suffixes.
