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 extended periods

may affect device reliability. Refer also to the SGS-THOMSON 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

have been stabilized. Valid data will appear on the

Switching Time Waveforms) depending on which is

limiting.

Deselect Mode. The M2716 is deselected by mak-

the condition of the addresses. The outputs are

M2716’s for memory expansion.

Standby Mode (Power Down). The M2716 may

be powered down to the standby mode by making

ically puts the outputs in the Hi-Z state. The power

is reduced to 25% (132 mW max) of the normal

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.

and the desired data word is applied to the output

data). After the address and data signals are stable
