Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part number may be subject to obsolescence or limited availability. Confirm that the specific suffix matches the required package and temperature grade. Check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure design-in documentation aligns with current Lattice product lifecycle status.

Complex Programmable Logic Devices Selection Notes

Select this model when high pin count (up to 192 I/O) and moderate density (384 macrocells) are required in a compact BGA footprint. Compare against the LC4384V series if higher voltage tolerance or different speed grades are needed. Verify that the 1.8V core voltage is compatible with the target system's power rails and I/O standards.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000C family, designed for high-performance CPLD applications requiring non-volatile configuration. It serves as a successor to earlier ispMACH 4000 variants, offering improved speed and density while maintaining compatibility with existing design tools and methodologies used for legacy Lattice devices.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the LC4384C family with different speed grades (e.g., LC4384C-5FN256C) or package options. Cross-family migration to ispMACH 4000V or MachXO series requires architectural review due to differences in logic structure and I/O capabilities.
