Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range variant when sourcing. Confirm the package type matches the required 176-pin LFQFP footprint. Ensure compatibility with existing design tools for the MachXO2 architecture. Check for lead-free and RoHS compliance status as per project requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring approximately 384 macrocells and a high pin count in a surface-mount QFP package. Compare against lower density variants if fewer resources are needed. Consider the 156 MHz speed grade relative to timing constraints. Verify that the 1.0 mm body height fits within the mechanical enclosure limits.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice MachXO2 series, which offers non-volatile flash-based CPLDs. The series is known for low power consumption and instant-on capabilities. The LC4384C represents a higher density option within the family, suitable for more complex logic functions compared to smaller devices like the LC4256 or LC4128.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other LC4384C variants with different speed grades or temperature ranges, such as LC4384C-5TN176C. Cross-family migration to newer Lattice families may require schematic and code re-verification due to architectural differences.
