Description
Verify sector
protect/
unprotect
Verifies write protection for sector. Sectors are protected from program/erase operations on commercial
programming equipment. Determine if sector protection exists in a system by writing the ID read command
sequence and reading location XXX02h, where address bits A12–18 select the defined sector addresses. A
logical 1 on DQ0 indicates a protected sector; a logical 0 indicates an unprotected sector.
Temporarily disables sector protection for in-system data changes to protected sectors. Apply +10V to RESET
Temporary
to activate temporary sector unprotect mode. During temporary sector unprotect mode, program protected
sector unprotect 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
Hold RESET low to enter deep power down mode (<1 µA). Recovery time to start of first read cycle is 50ns.
Automatic sleep
mode
Enabled automatically when addresses remain stable for 300ns. Typical current draw is 1 µA with no current
drawn by the external devices from teh output pin. 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.
