ICE40LP1K in Lattice iCE40 Family
The iCE40LP1K is a high-density, ultra-low-power FPGA sub-family within Lattice Semiconductor's iCE40 mobile platform. Featuring 1,280 Logic Cells and up to 64 Kbits of embedded RAM, these devices are specifically architected for space-constrained, battery-powered applications. They leverage a lookup-table-based architecture to provide hardware-level logic flexibility and near-zero standby current, making them ideal for mobile sensor management and custom logic expansion where traditional CPLDs or microcontrollers lack efficiency or I/O performance.

Comparing specs that differ across variants.
| Part Number | I/O Pins | Package | Stock |
|---|---|---|---|
| ICE40LP1K-CM49 (Lattice Semiconductor Corporation) | 35 | VFBGA-49 | 12 |
| ICE40LP1K-CM36 (Lattice Semiconductor Corporation) | 25 | VFBGA-36 | 5 |
| ICE40LP1K-CM36A (Lattice) | 25 | VFBGA-36 | 313 |
Variants within the iCE40LP1K sub-family are primarily distinguished by their physical packaging and pin counts. Options range from the compact 16-ball WLCSP for high-density mobile designs to the larger 84-pin QFN and 121-ball csBGA packages for designs requiring more user I/O. Some variants, like those ending in 'A', may feature subtle optimizations for specific automotive or industrial operating temperature ranges, though the underlying logic cell count remains consistent.
