connected to this device.
Address inputs (A0-A20)
The Address Inputs select the cells in the memory array to access during Bus Read
operations. During Bus Write operations they control the commands sent to the Command
Interface of the internal state machine.
Data input/output (DQ0-DQ15)
The Data I/O outputs the data stored at the selected address during a Bus Read operation
or inputs a command or the data to be programmed during a Write Bus operation.
Chip Enable (E)
The Chip Enable input activates the memory control logic, input buffers, decoders and
sense amplifiers. When Chip Enable is at V
mode. When Chip Enable is at V
impedance and the power consumption is reduced to the stand-by level.
Output Enable (G)
The Output Enable controls data outputs during the Bus Read operation of the memory.
Write Enable (W)
The Write Enable controls the Bus Write operation of the memory’s Command Interface.
The data and address inputs are latched on the rising edge of Chip Enable, E, or Write
Enable, W, whichever occurs first.
Write Protect (WP)
Write Protect is an input that gives an additional hardware protection for each block. When
Write Protect is at V
cannot be changed. When Write Protect is at V
can be locked or unlocked. (refer to
