bank address and the data 90h. The second cycle

need only contain the data 00h. The bank then returns

to the read mode.

The device offers accelerated program operations

through VPP. When the system asserts VID on this

input, the device automatically enters the Unlock

Bypass mode. The system may then write the

two- cy cle Unloc k Bypas s pr og r a m comman d

sequence. The device uses the higher voltage on the

VPP input to accelerate the operation. Note that sectors

must be unlocked using the Sector Lock/Unlock

command sequence prior to raising VPP to VID.

Figure 1 illustrates the algorithm for the program oper-

ation. Refer to the Erase/Program Operations table in

the AC Characteristics section for parameters, and

Figure 12 for timing diagrams.
