Embedded Programming Algorithm
The Embedded Program Setup is a command only op-
eration that stages the device for automatic program-
ming. Embedded Program Setup is performed by
writing 10h or 50h to the command register.
Once the Embedded Setup Program operation is per-
formed, the next WE# pulse causes a transition to an
active programming operation. Addresses are latched
on the falling edge of CE# or WE# pulse, whichever
happens later. Data is latched on the rising edge of
WE# or CE#, whichever happens first. The rising edge
of WE# also begins the programming operation. The
system is not required to provide further controls or
timings. The device will automatically provide an ade-
quate internally generated program pulse and verify
margin. The automatic programming operation is
completed when the data on DQ7 is equivalent to data
written to this bit (see Write Operation Status section)
at which time the device returns to Read mode.

Embedded Programming Algorithm
Note: See AC and DC Characteristics for values of VPP parameters. The VPP power supply can be hard-wired to the device or
switchable. When VPP is switched, VPPL may be ground, no connect with a resistor tied to ground, or less than VCC + 2.0 V. Refer
to Functional Description. Device is either powered-down, erase inhibit or program inhibit.
