Figure 13 Block Erase Instruction Sequence Diagram
Chip Erase (CE) (C7h/60h)
The Chip Erase (CE) instruction sets all bits to 1 (FFh). 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 Chip Erase (CE) instruction is entered by driving Chip Select (CS#) Low, followed by the instruction
code on Serial Data Input (DI). Chip Select (CS#) must be driven Low for the entire duration of the
sequence.
The instruction sequence is shown in Figure 14. Chip Select (CS#) must be driven High after the eighth bit
of the instruction code has been latched in, otherwise the Chip Erase instruction is not executed. As soon
as Chip Select (CS#) is driven High, the self-timed Chip Erase cycle (whose duration is t
CE
) is initiated.
While the Chip Erase cycle is in progress, the Status Register may be read to check the value of the Write
when it is completed. At some unspecified time before the cycle is completed, the Write Enable Latch
(WEL) bit is reset.
The Chip Erase (CE) instruction is executed only if all Block Protect (BP2, BP1, BP0) bits are 0. The Chip
Erase (CE) instruction is ignored if one, or more, sectors are protected.
