Data Sheet
Block Protection (BP3,BP2, BP1, BP0)
The Block-Protection (BP3, BP2, BP1, BP0) bits define the
size of the memory area, as shown in Table 5, to be soft-
ware protected against any memory Write (Program or
Erase) operation. The Write-Status-Register (WRSR)
instruction is used to program the BP3, BP2, BP1 and BP0
bits as long as WP# is high or the Block-Protect-Lock
(BPL) bit is 0. Chip-Erase can only be executed if Block-
Protection bits are all 0. After power-up, BP3, BP2, BP1
and BP0 are set to the defaults specified in Table 5.

FOR
The Security ID Status (SEC) bit indicates when the Secu-
Block Protection Lock-Down (BPL)
WP# pin driven low (V
Lock-Down (BPL) bit. When BPL is set to 1, it prevents any
further alteration of the BPL, BP3, BP2, BP1, and BP0 bits.
When the WP# pin is driven high (V
effect and its value is “Don’t Care”. After power-up, the BPL
bit is reset to 0.
Security ID Status (SEC)
rity ID space is locked to prevent a Write command. The
SEC is ‘1’ after the host issues a Lockout SID command.
Once the host issues a Lockout SID command, the SEC bit
can never be reset to ‘0.’
