• Flexible sysI/O buffer supporting LVCMOS, LVDS, SSTL, HSTL, PCI, and LVTTL standards
• Dedicated DDR memory interface logic supporting up to DDR400
• Integrated sysCLOCK PLLs for clock multiply, divide, and phase shifting

Field Programmable Gate Array Applications

• Cost-sensitive industrial infrastructure equipment
• Telecom base station connectivity modules
• Automotive control systems requiring low power consumption

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required speed grades and temperature ranges. Confirm that the 484-ball fpBGA package dimensions align with the target PCB footprint. Check for any Product Change Notifications regarding pinout or electrical parameter updates before finalizing procurement.

Field Programmable Gate Array Selection Notes

Select this model when designs require moderate logic density with extensive I/O capabilities in a compact form factor. The LFEC15E variant provides sufficient embedded memory for buffering without dedicated DSP blocks. Ensure the design utilizes the available two PLLs for clock management and verify that the 1.2V core voltage requirements are met by the system power rails.

Field Programmable Gate Array Part Context

This component is part of the LatticeEC family, which focuses on delivering essential FPGA features at a reduced cost compared to the LatticeECP series. Unlike the ECP variants, the EC family omits dedicated sysDSP blocks to lower manufacturing expenses while retaining robust logic, memory, and I/O resources suitable for general-purpose digital logic applications.

Field Programmable Gate Array Replacement Considerations

The LFEC15E-4FN484C has been superseded by the LFE2-35E-5FN484C. Designers migrating from this obsolete part should evaluate the newer device for improved performance metrics and updated toolchain support while maintaining similar package constraints.
