Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type matches the required 144-pin Thin Quad Flat Package (TQFP) dimensions. Ensure design files are compatible with the ispMACH 4000V architecture. Check for any recent Product Change Notifications regarding marking or assembly site changes. Validate that the 3.3V supply requirement aligns with the target system power rails.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with high performance is required. The 10 ns speed grade offers a balance between speed and power consumption compared to faster variants. Compare against the LC4128V-75 variant if higher speed (7.5 ns) is needed, noting potential differences in power dissipation. Consider the 144-pin footprint constraints during PCB layout. Verify that the 96 available I/Os meet the interface requirements of the application.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V family, designed for super-fast, high-density applications. It utilizes non-volatile technology, allowing designs to persist without external configuration memory. The family supports both 3.3V and lower voltage operations depending on the specific sub-series, though this specific model is optimized for 3.3V systems. It serves as a drop-in replacement for older GALs and PALs in complex logic designs.

Complex Programmable Logic Devices Replacement Considerations

The LC4128V-75TN144I is a verified similar alternative with faster switching speeds. Cross-reference pinouts to ensure compatibility with existing footprints. Evaluate power consumption differences between the 10 ns and 7.5 ns speed grades. Confirm that the replacement maintains the same 144-pin TQFP package dimensions.
