ICE40UL640 in Lattice iCE40 Family
The iCE40UL640 is a member of the iCE40 UltraLite family from Lattice Semiconductor, engineered specifically for mobile, wearable, and IoT applications where power consumption and physical footprint are critical constraints. Built on a 40nm low-power process, this FPGA family provides 640 logic cells in ultra-miniature packaging. It allows engineers to offload time-critical tasks from the primary application processor while maintaining an extremely low power profile during both active and standby modes of operation.
Variants in This Sub-Family
Variants within the iCE40UL640 sub-family primarily differ in their physical package options and temperature grades. Standard options include the ultra-small 16-ball WLCSP (0.35mm pitch), which is tailored for high-density consumer electronics. The parts are also categorized by industrial or commercial temperature ratings, ensuring reliability across varying thermal environments. While the core logic density remains constant at 640 LUTs, tape-and-reel quantities vary between 1K and 5K units for manufacturing scalability.
