32-KByte and 64-KByte Block-Erase
The 32-KByte Block-Erase instruction clears all bits in the selected 32 KByte block to FFH. A Block-
Erase instruction applied to a protected memory area will be ignored. The 64-KByte Block-Erase instruc-
tion clears all bits in the selected 64 KByte block to FFH. A Block-Erase instruction applied to a protected mem-
ory 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 command sequence. The 32-KByte Block-Erase
instruction is initiated by executing an 8-bit command, 52H, followed by address bits [A

driven high before the instruction is executed. The user may poll the Busy bit in the software status register or
wait T
cycles. See Figures 13 and 14 for the 32-KByte Block-Erase and 64-KByte Block-Erase sequences.
