Flexible sector architecture

Temporary

sector

unprotect

Temporarily disables sector protection for in-system data changes to protected sectors. Apply +10V to RESET

to activate temporary sector unprotect mode. During temporary sector unprotect mode, program protected

sectors by selecting the appropriate sector address. All protected sectors revert to protected state on removal

of +10V from RESET.

RESET

Resets the interal state machine to read mode. If device is programming or erasing when RESET = L, data

may be corrupted.

Deep

power down

Automatic

sleep mode

Enabled automatically when addresses remain stable for 300ns. Typical current draw is 1 µA. Existing data is

available to the system during this mode. If an address is changed, automatic sleep mode is disabled and new

data is returned within standard access times.
