Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix designation against official Lattice documentation to confirm the exact speed grade and temperature rating. Ensure the ordering part number matches the required package type and moisture sensitivity level. Cross-reference the manufacturer's latest datasheet to confirm current production status and availability constraints before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires moderate logic density with low power consumption and multi-voltage I/O flexibility. The 7.5 ns delay specification suits applications requiring fast combinatorial logic response. Consider the 48-pin TQFP form factor for surface-mount assembly requirements where pin count aligns with the 32 I/O limit.

Complex Programmable Logic Devices Part Context

This CPLD belongs to the ispMACH 4000V series, designed for cost-sensitive consumer and industrial applications. It utilizes Lattice's non-volatile Flash technology, allowing for unlimited reprogramming cycles. The family emphasizes ease of system integration and superior performance for power-sensitive designs compared to older EEPROM-based PLDs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may include other members of the Lattice ispMACH 4000V family with compatible pinouts and logic resources. Verify equivalent devices such as the LC4064V-75T48C if temperature ranges differ. Always validate timing specifications and I/O voltage levels against the original design requirements before substituting.
