    The iCE40 family of ultra-low power, non-volatile FPGAs has five devices
    with densities ranging from 384 to 7680 Look-Up Tables (LUTs). In addition
    to LUT-based,low-cost programmable logic, these devices feature Embedded
    Block RAM (EBR), Non-volatile Configuration Memory (NVCM) and Phase Locked
    Loops (PLLs). These features allow the devices to be used in low-cost,
    high-volume consumer and system applications.
