Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the
              Table "Absolute Maximum Ratings" 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 specification is not implied. Exposure to Absolute 
              Maximum Rating   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 Output is 0.5V with possible undershoot to 2.0V for a period
              less than 20ns. Maximum DC voltage on Output is VCC +0.5V with possible overshoot to VCC +2V for
             a period less than 20ns.
         3. Depends on range.

The M27V160 is a low voltage 16 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage. It 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 ROM.

The M27V160 operates in the read mode with a supply voltage as low as 3V. 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 M27V160 (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 rapidly to the device by following the programming procedure.

For applications where the content is programmed only one time and erasure is not required, the M27V160 is offered in PDIP42 and SO44 packages.
