LX256EV-5FN484I

Overview

The LX256EV-5FN484I is a Field Programmable Gate Array (FPGA) IC from the ispGDX2 series, designed for digital switching applications. It features 256 I/Os and is housed in a 484-FPBGA package measuring 23x23 mm. The device operates within a supply voltage range of 1.14V to 1.26V and supports a junction temperature range of -40°C to 100°C.

Feature Summary

• Configurable as a PCI Express switch integrated circuit
• Supports high-speed digital switching functions

Applications

• PCI Express switching systems
• Digital signal routing
• High-speed interface interconnects

Procurement Notes

Verify the exact suffix against official Lattice Semiconductor documentation to confirm pinout and electrical specifications. Ensure compatibility with required programming tools such as ispDOWNLOAD programmers. Confirm package dimensions match the 484-FPBGA (23x23) specification before integration into design layouts.

Selection Notes

Select this component when a dedicated FPGA-based PCI Express switch solution is required. Consider the 484-pin footprint and specific voltage requirements during PCB layout. Evaluate thermal management capabilities given the operating temperature range and power consumption characteristics typical of the ispGDX2 family.

Part Context

This part belongs to the ispGDX2 family, which provides flexible logic resources for specialized switching and control applications. The E variant typically denotes enhanced performance or specific feature sets within the series. It serves as a programmable alternative to fixed-function crosspoint switches.

Replacement Considerations

Check for direct substitutes within the ispGDX2 family with compatible pinouts. Verify if other variants offer similar I/O counts but different package sizes or speed grades. Consult official replacement guides for any discontinued or end-of-life notices.
