Serial NOR Flash Memory

3.0V Multi I/O with 4KB, 32KB & 64KB Sector/Block Erase

VER 1.2

As soon as CS# is driven high, the self-timed Write Status Register cycle (whose duration is tW) is

initiated. While the Write Status Register cycle is in progress, the Status Register can still be read to check

the value of the Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1 during the self-timed

Write Status Register cycle, and is 0 when it is completed. When the cycle is completed, the Write Enable

Latch (WEL) is reset.

The Write Status Register (WRSR) command allows the user to change the values of the Block Protect

(BP4, BP3,BP2, BP1, and BP0) bits, to define the size of the area that is to be treated as read-only, as

defined in Table1. The Write Status Register (WRSR) command also allows the user to set or reset the

Status Register Protect (SRP) bit in accordance with the Write Protect (WP#) signal. The Status Register

Protect (SRP) bit and Write Protect (WP#) signal allow the device to be put in the Hardware Protected

Mode. The Write Status Register (WRSR) command is not executed once the Hardware Protected Mode

is entered.
