DESCRIPTION
It is organized as 262,144 by 16 bits. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery recharges. The FDIP40W (window ceramic frit-seal package) has a transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure. Table 1.
