It is ideally suited for microprocessor systems requiring large data or program storage and is organized as 65,536 words by 16 bits. The M27W102 operates in the read mode with a supply voltage as low as 2.7V at –40 to 85 °C tem- perature range. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery re- charges. The FDIP40W (window ceramic frit-seal package) has a transparent lid which allows the user to ex- pose the chip to ultraviolet light to erase the bit pat- tern. A new pattern can then be written to the device by following the programming procedure. For application where the content is programmed only one time and erasure is not required, the M27w102 is offered in PDIP40, PLCC44 and TSOP40 (10 x 14 mm) packages. Figure 1.
