Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'MN132' against official Lattice documentation to confirm the package type and temperature grade, as datasheets may list variations like TN100. Ensure the ordering part number matches the required speed grade (-45) and that the manufacturer source provides valid RoHS compliance certificates. Cross-reference the Mouser or DigiKey part numbers with the official Lattice product selector guide to avoid counterfeit components.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile CPLD functionality is required with low power constraints. The 256 macrocell count offers sufficient logic density for moderate complexity designs. Compare the 4.5 ns delay against system timing requirements. Consider the 1.8 V supply voltage compatibility with other system components. Evaluate the CSBGA-132 footprint against available PCB space and thermal management capabilities.

Complex Programmable Logic Devices Part Context

This device belongs to the Lattice ispMACH 4000ZE series, designed for high-performance, low-power applications. It combines the ease of use of PLDs with the density of CPLDs. The series is known for its robust security features and flexible I/O options. It serves as a drop-in replacement for many older programmable logic families while offering enhanced performance and lower power consumption.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the LC4256 family with compatible packages, such as LC4256V-45MN132C if voltage levels differ. Verify pin-to-pin compatibility before substitution. Check if alternative speed grades meet timing requirements. Ensure that any substitute maintains the same non-volatile configuration capability and I/O drive strengths.
