The White 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 relation-
ships. A write cycle begins with address application,
write enable and chip select. Chip select is accom-
plished 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.
