Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to 105°C). Confirm the package type is 144-TQFP (20x20 mm). Check for recent Product Change Notices regarding marking or assembly site changes. Ensure compatibility with 3.3 V logic levels. Consult official Lattice documentation for humidity sensitivity handling requirements.

Complex Programmable Logic Devices Selection Notes

Select this part when 128 macrocells and 96 I/Os are required in a 144-pin package. Choose the '75' speed grade for 7.5 ns delay performance. Consider the 'V' series variant for 3.3 V/2.5 V/1.8 V support. Compare against LC4128V-5TN144I if faster switching speeds are needed. Verify power consumption specifications against system thermal constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V family of high-density CPLDs. These devices offer non-volatile configuration data and support multiple voltage domains. The family provides a balance of performance and flexibility for embedded logic applications. The LC4128V variant specifically targets designs needing moderate density with high I/O counts.

Complex Programmable Logic Devices Replacement Considerations

LC4128V-5TN144C is listed as a potential alternative. Verify that the lower delay time of the substitute meets timing requirements. Confirm pinout compatibility between the TN144I and TN144C variants. Check if the commercial temperature range of the substitute is sufficient for the application environment.
