DESCRIPTION The M27C160 is a 16 Mbit EPROM offered i n the two ranges UV (ultra violet erase) and O TP (one time programmable). It is i deally suited for microprocessor systems requiring large data or program storage and is organised as either 2 Mbit words of 8 bit or 1 Mbit words of 16 bit. The pin-out is compatible with a 16 Mbit Mask R OM. The FDIP42W (window ceramic frit-seal package) has a transparent l id which allows th e user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern c an then be written rapidly to the device by following t he programming procedure. For applications where the content is programmed only one t ime and erasure is not required, t he M27C160 is of fered in PDIP42, SDIP42, PLCC44 and SO44 packages.

Note: 1. Except f or th e ra ting "O perating T emperature R ange", stresses above those listed in t he Table " Absolute Maximum R atings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this s pecification is not im plied. Exposure to Absolute Maximum R ating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents. 2. Minimum DC voltage on Input or O utput is 0.5V w ith possible undershoot t o 2.0V fo r a period less than 20ns. Maximum DC voltage on Out put is VCC +0. 5V with possible overshoot to VCC +2V for a peri od less than 20ns. 3. Depends on range.
