DESCRIPTION

Write Enable: Determines if a given cycle is a WRITE cycle. If WE# is

LOW, the cycle is either a WRITE to the command state machine (CSM)

or to the memory array.

Write Protect: Unlocks the soft-protected blocks when HIGH if VPP =

1.65V–3.465V or 12V and RP# = VIH for WRITE or ERASE. Does not

affect WRITE or ERASE operation on other blocks.

Chip Enable: Activates the device when LOW. When CE# is HIGH, the

device is disabled and goes into standby power mode.

Reset/Power-Down: When LOW, RP# clears the status register, sets the

write state machine (WSM) to the array read mode and places the

device in deep power-down mode. All inputs, including CE#, are

“Don’t Care,” and all outputs are High-Z. RP# must be held at VIH

during all other modes of operation.

Output Enable: Enables data output buffers when LOW. When OE# is

HIGH, the output buffers are disabled.

Address Inputs: These address inputs select a unique, 16-bit word out

of the 1,048,576 available.

Data I/O: These data I/O are data output lines during any READ

operation or data input lines during a WRITE. Data I/O are used to

input commands to the CSM.

Write/Erase Supply Voltage: From a WRITE or ERASE CONFIRM until

completion of the operation, VPP must be 1.65V–3.465V or 12V. VPP =

“Don’t Care” during all other operations.

Power Supply: 3.3V ±5%.

I/O Supply Voltage: 3.3V ±5%.

Ground.
