Product details

Logic density and on-chip memory for sensor fusion and display bridging

The ICE40UP5K-SG48I: The 39 user I/O, brought out to a 48-QFN with a 7x7 mm body and exposed thermal pad, suit this part for sensor aggregation or display-bridge roles where board area is tight and the thermal path to the ground plane matters.

Supply rails and temperature grade for industrial edge duty

Core supply is 1.14 V to 1.26 V — a 1.2 V rail with ±5 % regulation keeps the FPGA within spec. The 48-VFQFN exposed pad (7x7 mm) requires a thermal via array under the paddle to pull heat into the inner-layer copper pour; the datasheet's recommended footprint keeps the junction below 100 °C at full toggle rate.

Frequently asked questions

Will ICE40UP5K-SG48I drop into a board designed for ICE40UP3K-UWG30ITR1K without rewiring?

No — the UP5K comes in a 48-QFN (7x7 mm) with 39 I/O, while the UP3K uses a 30-ball WLCSP (2.6x2.9 mm) with 21 I/O. The package footprint and ball-out are completely different; a board spin is required.

What compliance documentation does Lattice provide for ICE40UP5K-SG48I?

Lattice certifies ROHS3 compliance per the product status. Full material declaration, REACH SVHC disclosure, and conflict-minerals reporting are available through the Lattice compliance portal.
