Data Sheet
Read-Array Command
Upon initial device power-up and after exit from reset, the device defaults to the read array mode. This
operation can also be initiated by writing the Read-Array command. (See Table 8.) The device remains
available for array reads until another command is written. Once an internal Program/Erase operation
starts, the device will not recognize the Read-Array command until the operation is completed, unless
the operation is suspended via a Program/Erase Suspend command.
Read-Software-ID Command
The Read-Software-ID operation is initiated by writing the Read-Software-ID command. Following the
command, the device will output the manufacturer’s ID and device ID from the addresses shown in
Table 9. Any other valid command will terminate the Read-Software-ID operation.
The Read-Software-ID command is the same as the Read-Security-ID command. See “Security ID
Commands” on page 19.

1. Address shown in this column is for boot device only. Address locations should appear elsewhere in the 4 GByte sys-
tem memory map depending on ID strapping values on ID[3:0] pins when multiple LPC memory devices are used in a
system.
Read-Status-Register Command
The Status register may be read to determine when a Sector-/Block-Erase or Program completes, and
whether the operation completed successfully. The Status register may be read at any time by writing
the Read-Status-Register command. After writing this command, all subsequent Read operations will
return data from the Status register until another valid command is written.
The default value of the Status register after device power-up or reset is 80H.
