Complex Programmable Logic Devices Procurement Notes

This component is listed as obsolete or discontinued by the manufacturer. Availability is limited to existing stock or surplus channels. Verify RoHS compliance status and moisture sensitivity level before procurement, as these may vary based on production date. Ensure compatibility with existing design files if replacing older inventory.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design logic requirements. The TN100 package offers a balance of I/O count and board space. Compare against the LC4064V series for potential pin-compatible upgrades if higher density or different voltage options are needed later. Confirm that the 7.5 ns delay meets the system timing constraints.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4000B family, designed for high-performance CPLD applications. It succeeds earlier generations like the LC4000B series, offering improved speed and density. The 'B' suffix denotes the specific generation within the 4000B line, while 'I' indicates the industrial temperature grade.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to obsolescence. Consider the LC4064V-75TN100I as a potential functional equivalent if available in stock, though verification of electrical parameters is required. Cross-reference with newer Lattice MachXO or iCE40 families for modern alternatives, noting architectural differences.
