Complex Programmable Logic Devices Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer, with a final shipment date specified as August 12, 2026. Verification of remaining stock availability through authorized distributors is essential prior to design commitment. Designers should confirm RoHS compliance status and moisture sensitivity levels directly with suppliers, as these attributes may vary based on production batch dates and specific distributor inventory sources.

Complex Programmable Logic Devices Selection Notes

Select this CPLD when designing for environments requiring operation up to +130°C junction temperature. The 128-macrocell density suits moderate complexity logic functions. Ensure the application requires the specific 7.5 ns speed grade and 3.3 V nominal supply voltage. Verify that the TQFP-100 footprint aligns with PCB layout constraints. Consider alternative Lattice families if long-term supply continuity is a critical project requirement given the EOL status.

Complex Programmable Logic Devices Part Context

The LC4128V-75T100E belongs to the Lattice ispMACH 4000V series, which targets high-performance, low-power applications. This series utilizes advanced CMOS technology to deliver fast switching speeds while maintaining low power consumption. The device supports in-system programming, allowing for field updates and design iterations without removing the chip from the circuit board, enhancing development flexibility.

Complex Programmable Logic Devices Replacement Considerations

Public documentation identifies the LA4128V-75TN100E as a similar replacement option. The LA variant offers AEC-Q100 automotive qualification but operates at a lower maximum frequency of 168 MHz compared to the LC4128V's 333 MHz. Both devices share identical macrocell counts, I/O configurations, and packaging styles, facilitating potential pin-compatible transitions where speed requirements allow.
