Data Sheet
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 23 -A 0 ]. Address
bits [A MS -A 15 ] (A MS = Most Significant Address) are used to determine block address (BA X ), remaining
address bits can be V IL or V IH. CE# must be driven high before the instruction is executed. The 64-KByte Block-
Erase instruction is initiated by executing an 8-bit command D8H, followed by address bits [A 23 -A 0 ]. Address bits
[A MS -A 15 ] are used to determine block address (BA X ), remaining address bits can be V IL or V IH. CE# must be
driven high before the instruction is executed. The user may poll the Busy bit in the software status register or
wait T BE for the completion of the internal self-timed 32-KByte Block-Erase or 64-KByte Block-Erase
cycles. See Figures 13 and 14 for the 32-KByte Block-Erase and 64-KByte Block-Erase sequences.
