A 11/06/2015 8.13 CHIP ERASE OPERATION (CER, C7h/60h) A Chip Erase (CER) instruction erases the entire memory array. Before the execution of CER instruction, the Write Enable Latch (WEL) must be set via a Write Enable (WREN) instruction. The WEL is automatically reset after completion of a chip erase operation. The CER instruction code is input via the SI. Erase operation will start immediately after CE# is pulled high, otherwise the CER instruction will not be executed. The internal control logic automatically handles the erase voltage and timing.
