Description

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.

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

may be corrupted.

Hold RESET low to enter deep power down mode (<1 µA). Recovery time to start of first read cycle is 50ns.

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.

In word mode, there are one 8K word, two 4K word, one 16K word, and fifteen 32K word sectors. Address range is A18–A-1 if BYTE = VIL; address range is

A18–A0 if BYTE = VIH.
