Logic density and I/O budget
The ICE40LP8K-CM225 packs 7680 logic cells (960 LABs/CLBs) and 128 Kbit of embedded SRAM — enough for sensor fusion glue logic, a small state machine, or bridging a parallel bus to a serial peripheral without an external FIFO.
225-VFBGA (also designated 225-UCBGA) — 7×7 mm array, 0.5 mm ball pitch. The outer two ball rows route on the top layer; inner rows need at least a four-layer stack with 0.2 mm via capture pads and a 0.1 mm trace/space rule. Surface-mount only — no socketed option. The package ships in trays; the 0.5 mm pitch demands a stencil aperture of 0.3 mm square for a 1:1 ball-to-pad ratio to avoid solder bridging.
