ES29LV800 Device Bus Operations Legend: L=Logic Low=VIL, H=Logic High=VIH, VID=11.5-12.5V, X=Don’t Care, SA=Sector Address, AIN=Address In, DIN=Data In, DOUT=Data Out Notes: 1. Addresses are A18:A0 in word mode (BYTE#=VIH) , A18:A-1 in byte mode (BYTE#=VIL). 2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector Pro- tection and Unprotection” section. 3. DIN or DOUT as required by command sequence, data polling, or sector protection algorithm.
