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
sec delay timer to permit page mode operation.
Each subsequent WE transition from high to low that occurs
before the completion of the 150
sec time out will restart the
timer from zero. The operation of the timer is the same as a
retriggerable one-shot.
