Integrated Circuit
1 Mbit (128Kb x 8) UV EPROM
Description:
The NTE27C1001 is a 1 Mbit EPROM in a 32−Lead DIP type package ideally suited for microproces-
sor systems requiring large programs and is organized as 131,072 by 8 bits. This device has a trans-
parent 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.

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.
Note 2. Minimum DC voltage on the 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 over-
shoot to VCC +2V for a period less than 20ns.
