Sector-Erase
The Sector-Erase instruction clears all bits in the selected 4 KByte sector to FFH. A Sector-Erase
instruction applied to a protected memory area will be ignored. Prior to any Write operation, the Write-
Enable (WREN) instruction must be executed. CE# must remain active low for the duration of any com-
mand sequence. The Sector-Erase instruction is initiated by executing an 8-bit command, 20H, fol-
lowed by address bits [A
determine the sector address (SA
before the instruction is executed. Poll the Busy bit in the software status register or wait T
completion of the internal self-timed Sector-Erase cycle. See Figure 12 for the Sector-Erase sequence.
