Flexible sector architecture
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 = V
is A18–A0 if BYTE = V

Bottom boot sector architecture (AS29LV800B)
Description
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 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 (
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.
