Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix codes against official Lattice documentation to confirm temperature range and packaging details. Ensure compatibility with existing board layouts regarding pin assignments and power requirements. Cross-reference the date code and lot information if traceability is required for your application.

Complex Programmable Logic Devices Selection Notes

Select this model when requiring moderate logic density with low static power consumption. The MachXO family offers superior performance over traditional CPLDs while maintaining ease of design. Consider the -10 speed grade for designs requiring up to 100 MHz system clock frequencies. Evaluate the I/O count needs against the 192-pin limit of the F256 package.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice MachXO series, which bridges the gap between simple PLDs and complex FPGAs. It utilizes Lattice's proprietary non-volatile flash process, eliminating the need for external configuration memory. This series is widely used in cost-sensitive, low-power applications where instant-on capability is critical.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements may include other Lattice MachXO variants with similar macrocell counts. For legacy GAL replacements, verify pin-to-pin compatibility and timing requirements. No direct cross-manufacturer equivalents exist due to unique flash architecture; functional substitutes require redesign.
