ICE40UL1K in Lattice iCE40 Family

The iCE40UL1K family, part of Lattice Semiconductor's iCE40 UltraLite series, represents the industry's smallest and lowest-power FPGAs designed specifically for mobile and handheld devices. Built on 40nm CMOS technology, these devices provide 1248 Look-Up Tables (LUTs) with incredibly low static current consumption. They are engineered to offload time-critical or power-hungry tasks from the application processor, such as sensor management, LED control, and signal level shifting in space-constrained hardware designs.

Variants in This Sub-Family

Variants within the ICE40UL1K sub-family are distinguished primarily by their packaging and temperature ratings. The CM36 suffix denotes a 36-ball VFBGA package with a 0.4mm pitch, suitable for standard PCB assembly, while the SWG16 indicates an ultra-miniature 16-ball Wafer Level Chip Scale Package (WLCSP). Parts are further identified by their ordering quantities, such as the TR1K suffix which specifies tape-and-reel packaging for high-volume automated manufacturing environments.
