Figure 15. Bulk Erase ( BE ) Instruction Sequence

Instruction
Bulk Erase (BE)
The Bulk Erase (BE) instruction sets to 1(FFh) all bits
inside the entire memory. Before it can be accepted,
a Write Enable (WREN) instruction must previously
have been executed. After the Write Enable (WREN)
instruction has been decoded, the device sets the
Write Enable Latch (WEL).
The Bulk Erase (BE) instruction is entered by driving
Chip Select (CS#) Low, followed by the instruction
code, Serial Data Input (SI). No address is required
for the Bulk Erase (BE). Chip Select (CS#) must be
driven Low for the entire duration of the sequence.
The instruction sequence is shown in Figure 15.
As soon as Chip Select (CS#) is driven High, the
self-timed Bulk Erase cycle (whose duration is t
BE
)
is initiated. While the Bulk Erase cycle is in
progress, the Status Register may be read to check
the value of the Write In Progress (WIP) bit. The
Write In Progress (WIP) bit is 1 during the self-
timed Bulk Erase cycle, and is 0 when it is com-
pleted. At some unspecified time before the cycle is
completed, the Write Enable Latch (WEL) bit is
reset.
A Bulk Erase (BE) instruction is executed only if all
the Block Protect (BP2, BP1, BP0) bits (see Table
1) are set to 0. The Bulk Erase (BE) instruction is
ignored if one or more sectors are protected.
