Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors due to potential availability issues. Confirm RoHS compliance status as specifications may vary by manufacturing batch. Check for moisture sensitivity level requirements prior to surface mount assembly. Ensure programming tools support the specific EEPROM architecture of the ispMACH 4000C series.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design logic. The 7.5 ns speed grade suits applications requiring moderate timing margins. Compare against the LC4064ZE series if lower static power consumption is critical, noting that ZE variants may offer different performance characteristics. Ensure the TQFP-100 package fits the PCB footprint constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, which bridges the gap between complex GALs and FPGAs. The 'C' suffix denotes the 1.8 V core voltage variant. The '25' indicates the -25 speed grade (7.5 ns). The 'T100' specifies the 100-pin Thin Quad Flat Package. This family is known for predictable timing and ease of use compared to FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package include other speed grades of the LC4064C series such as LC4064C-5T100C or LC4064C-75T100C, provided timing requirements are met. Cross-family upgrades to the LC4064ZE series require verification of pin compatibility and power budget differences.
