Table 2. Absolute Maximum Ratings
Note: 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 ex tended periods
may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.

DEVICE OPERATION
The M2716 has 3 modes of operation in the normal
system environment. These are shown in Table 3.
Read Mode. The M2716 read operation requires
that G = V
have been stabilized. Valid data will appear on the
output pins after time t

Programming
The M2716 is shipped from SGS-THOMSON com-
pletely erased. All bits will be at “1" level (output
high) in this initial state and after any full erasure.
Table 3 shows the 3 programming modes.
Program Mode. The M2716 is programmed by
introducing “0"s into the desired locations. This is
done 8 bits (a byte) at a time. Any individual address,
sequential addresses, or addresses chosen at ran-
dom may be programmed. Any or all of the 8 bits
associated with an address location may be pro-
grammed with a single program pulse applied to the
EP pin. All input voltage levels including the program
pulse on chip enable are TTL compatible.
The programming sequence is: with V
= 5V, G = V
and the desired data word is applied to the output
pins (V
data). After the address and data signals are stable
the program pin is pulsed from V
