Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited for legacy CPLD families. Ensure proper handling for moisture-sensitive devices during storage and reflow soldering processes.

Complex Programmable Logic Devices Selection Notes

Select this model when a low-pin-count CPLD with high-speed performance (400 MHz) is required. Compare against the LC4064B series for similar density but different speed grades or voltage requirements. Consider the LC4064C-10T48I if a slower speed grade (10 ns delay) offers cost advantages for less timing-critical designs.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4064C family, which succeeded the 4064B series. The family is characterized by its use of EEPROM technology, allowing for rapid prototyping and field reprogrammability without the need for external configuration memory.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package include other variants of the LC4064C family, such as the LC4064C-10T48I, provided the timing specifications meet the design requirements.
