The WEDC 68 lead CQFP
fills the same fit and function
as the JEDEC 68 lead CQFJ
or 68 PLCC. But it has the
TCE and lead inspection
advantage of the CQFP
form.

WRITE
A write cycle is initiated when OE# is high and a low pulse
is on WE# or CS# with CS# or WE# low. The address
is latched on the falling edge of CS# or WE# whichever
occurs last. The data is latched by the rising edge of CS#
or WE#, whichever occurs first. A byte write operation will
automatically continue to completion.

write cycle timing
Figures 5 and 6 show the write cycle timing relationships.
A write cycle begins with address application, write enable
and chip select. Chip select is accomplished by placing
the CS# line low. Write enable consists of setting the WE#
line low. The write cycle begins when the last of either CS#
or WE# goes low.
The WE# line transition from high to low also initiates
an internal 150 µsec delay timer to permit page mode
operation. Each subsequent WE# transition from high to
low that occurs before the completion of the 150 µsec time
out will restart the timer from zero. The operation of the
timer is the same as a retriggerable one-shot.
