Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against official Lattice documentation to confirm temperature grade and package variant. Confirm RoHS compliance status as legacy EC devices may have different environmental certifications compared to current portfolios. Ensure design files match the exact revision level required for production integration.

Field Programmable Gate Array Selection Notes

Select this model when system requirements align with approximately 3.1K LUTs and 195 available I/O resources. Consider the 1.2V core voltage requirement for power budget calculations. Evaluate the 256-pin footprint constraints during PCB layout planning to ensure adequate routing space for the 17x17mm package dimensions.

Field Programmable Gate Array Part Context

This component belongs to the Lattice EC FPGA family, which targets cost-sensitive and power-efficient applications. The EC series is characterized by its dense logic architecture relative to its power consumption profile. It serves as a foundational programmable logic solution for embedded systems before transitioning to newer families like ECP or CrossLink.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are not explicitly documented in public sources for this legacy part number. Designers should consult Lattice's migration guides for transitioning to the LatticeXP or LatticeECP families, ensuring resource mapping and I/O compatibility are addressed.
