A12 08/04/2020 8.11 SECTOR ERASE OPERATION (SER, D7h/20h) A Sector Erase (SER) instruction erases a 4 Kbyte sector before the execution of a SER instruction, the Write Enable Latch (WEL) must be set via a Write Enable (WREN) instruction. The WEL bit is automatically reset after the completion of Sector Erase operation. A SER instruction is entered, after CE# is pulled low to select the device and stays low during the entire instruction sequence The SER instruction code, and three address bytes are input via SI. Erase operation will start immediately after CE# is pulled high. The internal control logic automatically handles the erase voltage and timing. The progress or completion of the erase operation can be determined by reading the WIP bit in the Status Register using a RDSR instruction. If the WIP bit is “1”, the erase operation is still in progress. If the WIP bit is “0”, the erase operation has been completed.
