Lattice Semiconductor Corporation LX256EB-35F484C

The ispGDX2 family provides programmable digital signal routing and I/O interfacing. The LX256EB-35F484C code identifies a 256-I/O B-voltage device with no sysHSI support. Its configuration and electrical limits must be checked against the Lattice family data sheet for the intended board.

Lattice identifies F484 as a 484-ball fpBGA package. The LCDChip catalog records 484-BBGA; the package registry uses that same name and maps it to /upload/package/484-BBGA.jpg. BBGA and fpBGA labels alone do not establish mechanical equivalence. Verify the Lattice ball map, outline, pitch and land pattern before layout release.

Assembly checks

• Use the Lattice 484-ball fpBGA mechanical drawing.
• Confirm ball-one orientation and power-bank assignments.
• Do not assume the catalog BBGA name proves footprint equivalence.

The registered JPG is absent locally and returns HTTP 404 on the production site. Publication must remain on hold.

Use Lattice's exact 256B/484-ball BSDL and package ball map for individual ball assignments. The groups below are functional references, not a ball-by-ball substitute.

Validate all power, ground, reset and bank-interface pins against the controlled Lattice ball assignment before PCB sign-off.

Decode values are ordering-code and family-level data; confirm electrical limits and timing test conditions in Lattice's full data sheet.

Lattice marks this exact code discontinued. No automatic drop-in substitute is asserted. Compare routing resources, I/O standards, bank voltages, timing, programming flow, BSDL and the controlled 484-ball footprint before migration. No internal substitute link is shown without an exact API catalog match and manufacturer-supported compatibility evidence.

Lattice's ispGDX2V/B/C family data sheet lists LX256EB-35F484C in the ordering information and decodes its voltage, speed, package and grade. The Lattice mature-device page provides family documentation and 256B 484-ball BSDL resources. Use those controlled documents for qualification.

Confirm full device marking, traceability and storage/handling history for this discontinued code. Check programmable functionality, supply-bank compatibility and timing on the actual board design. The unverified catalog package mapping and unavailable image require review.

This page is a selection aid, not a replacement for controlled Lattice documentation. Hold publication until the catalog 484-BBGA and Lattice fpBGA mechanical mapping is confirmed and the registered JPG is accessible on the production site.
