3520 logic elements in a 4x4 mm footprint
The ICE40LP4K-CM81 packs 3520 logic elements and 63 I/O into an 81-ball VFBGA that measures 4x4 mm — the smallest footprint in the iCE40 LP family for this logic density. The 81920 total RAM bits give you on-chip block memory for line buffers or small FIFOs without external SRAM.
Core supply and temperature grade
Core voltage runs from 1.14 V to 1.26 V — a single 1.2 V rail powers the fabric.
The supplier device package is 81-UCBGA (4x4), the same physical footprint. Surface-mount assembly; the tray packaging keeps the balls undamaged through reflow.
ROHS3 compliant, so it clears the REACH and RoHS exemption gates for EU-market builds.
