Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist in the market. Confirm RoHS compliance status via official datasheets before procurement. Check for obsolescence notices as this model may be discontinued or superseded by newer families. Ensure proper ESD handling procedures are followed during storage and assembly due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this component when 64 macrocells and 32 I/Os meet design requirements within a TQFP-48 footprint. Consider the 7.5 ns delay for timing-critical paths up to 400 MHz. Verify voltage compatibility with 2.5 V logic levels. Compare against LC4064V series if lower cost is prioritized over speed, or LA4064Z series for automotive qualification needs.

Complex Programmable Logic Devices Part Context

This CPLD belongs to the ispMACH 4000B family, designed for high-performance programmable logic applications. It succeeds earlier ispMACH 4000 devices with improved speed and density. The part number suffix '75' indicates the 7.5 ns speed grade, while 'T48' specifies the TQFP-48 package. The 'I' denotes industrial temperature range capability.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other LC4064B variants with different speed grades or packages. For upgraded performance, consider the LC4064V series which offers similar functionality. Automotive applications should utilize the LA4064Z series instead. Verify that any substitute maintains the same I/O count and macrocell architecture.
