ICE40UP3K in Lattice iCE40 Family
The ICE40UP3K is a member of the Lattice Semiconductor iCE40 UltraPlus family, designed specifically for low-power, space-constrained mobile and IoT applications. This sub-family provides a balance of 2.8K look-up tables (LUTs) and substantial embedded RAM, allowing engineers to implement hardware-accelerated functions like sensory buffering and voice recognition. By offloading these tasks from a power-hungry application processor, the ICE40UP3K enables always-on functionality while maintaining an extremely small physical footprint and minimal battery drain.
Variants within the ICE40UP3K sub-family primarily differ in their physical packaging and temperature grading. Engineers can choose between ultra-small 0.4mm pitch Wafer Level Chip Scale Packages (WLCSP) for high-density mobile designs or more accessible 48-pin QFN packages for easier PCB routing. Additionally, industrial-grade variants offer extended temperature support compared to standard commercial offerings, ensuring reliability in harsher operating environments without altering the core logic capacity or power profile.
