SIGNAL DESCRIPTIONS
See Figure 1, Logic Diagram, and Table 1, Signal
Names, for a brief overview of the signals connect-
ed to this device.
Address Inputs (A0-A19).
The Address Inputs
select the cells in the memory array to access dur-
ing Bus Read operations. During Bus Write opera-
tions they control the commands sent to the
Command Interface of the internal state machine.
Data Inputs/Outputs (DQ0-DQ7).
The Data In-
puts/Outputs output thedata stored atthe selected
address during a Bus Read operation. During Bus
Write operations they represent the commands
sentto the Command Interfaceof theinternal state
machine.
Chip Enable (E).
The Chip Enable, E, activates
the memory, allowing Bus Read and Bus Write op-
erations to be performed. When Chip Enable is
High, V
IH
, all other pins are ignored.
Output Enable (G).
The Output Enable, G, con-
trols the Bus Read operation of the memory.
Write Enable (W).
The Write Enable, W, controls
the Bus Write operation of the memory’s Com-
mand Interface.
Reset/Block Temporary Unprotect (RP).
The Re-
set/Block Temporary Unprotect pin can be usedto
apply a Hardware Reset to the memory or to tem-
porarily unprotect all blocks that have been pro-
tected.
Table 2. Absolute Maximum Ratings
(1)
Note: 1. Except for the rating ”O(jiān)perating 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 condi-
tions for extended periods may affect device reliability. Referalso to the STMicroelectronics SUREProgram andother relevant qual-
ity documents.
2. Minimum Voltage may undershoot to –2V during transition and for less than 20ns during transitions.
