Description:
The NTE2532 is a 32,768–bit, ultraviolet–light–erasable, electrically–programmable read–only
memory in a 24–Lead DIP type package. This device is fabricated using N–channel silicon–gate
technology for high speed and simple interface with MOS and bipolar circuits. All inputs (including
program data inputs) can be directly driven by Series 74 TTL circuits without the use of external pull–
up reistors, and each output can drive one Series 74 circuit without external resistors. The data out-
puts are three–state for connecting mutiple devices to a common bus.
Since the NTE2532 operates from a single +5V supply (in the read mode), it is ideal for use in micro-
processor systems. One other (+25V) supply is needed for programming but all programming signals
are TTL level, requiring a single 10ms pulse. For programming outside of the system, existing
EPROM programmers can be used. Locations may be programmed singly, in blocks, or at random.
Total programming time for all bits is 41 seconds.
