Lattice Semiconductor Corporation LX64B-5F100C

LX64B-5F100C is an in-system-programmable digital crosspoint device in Lattice's ispGDX2 family. Its ordering row identifies 64 I/Os, the B-series 2.5 V core-voltage class, a 5.0 ns propagation-delay grade, conventional F100 package and commercial grade. Programmable routing can replace fixed interconnect arrangements in suitable parallel digital interfaces.

The manufacturer describes F100 as a conventional 100-ball fpBGA; FN100 is a separate lead-free order code. The LCDChip record uses the broader label 100-LBGA. Verify body dimensions, ball pitch, A1 orientation and land pattern against the controlled Lattice package drawing, not the generic catalog label alone.

Layout checks

• Confirm the 100-ball F100 mechanical drawing and A1 orientation.
• Check every ball assignment and required power connection.
• Do not treat F100 and FN100 as identical assembly specifications.

The registered package JPG is currently unavailable on the production site; this detail must not be published until the image is supplied and verified.

The exact 100-ball fpBGA ball map in the Lattice data sheet controls layout and signal assignment. Functional groups include user I/O, core and I/O-bank supplies, ground, configuration and test connections.

This summary is not a ball-by-ball pinout; consult the official 100-ball table before schematic or PCB sign-off.

The speed-grade figure is not a substitute for full timing analysis under actual voltage, loading and temperature conditions.

Lattice PCN09I-10 identifies LX64V-5F100C as a recommended successor to LX64B-5F100C. The V-series voltage requirements differ from the B-series option, so a pin-compatible recommendation is not an automatic electrical replacement. Review rails, I/O-bank levels, timing, programming image, package and qualification before substitution. No internal product link is provided without an exact catalog API match.

The official Lattice ispGDX2 family data sheet contains the exact LX64B-5F100C ordering entry. Lattice PCN09I-10 identifies its lifecycle change and suggested V-series alternative. Use current manufacturer-controlled documentation and drawings for final engineering decisions.

For a discontinued device, verify the exact marking and order code, manufacturer documentation, traceability, date and lot codes, ball condition, moisture-sensitive handling and applicable test evidence. Confirm whether the offered unit is the conventional F100 variant; do not infer lead-free status from a generic catalog package name.

Confirm the official data sheet, PCN, complete ball map, mechanical drawing, electrical conditions and lifecycle requirements before specifying this legacy part or a successor. The missing production package JPG must be resolved and the rendered page rechecked before release.
