12.9
Asynchronous Read Operation (Non-Burst)
The device has two control functions which must be satisfied in order to obtain data at the outputs. CE# is the
power control and is used for device selection. OE# is the output control and is used to gate data to the output
pins if the device is selected. The device is powered-up in an asynchronous read mode. In the asynchronous
mode the device has two control functions which must be satisfied in order to obtain data at the outputs. CE#
is the power control and is used for device selection. OE# is the output control and is used to gate data to the
output pins if the device is selected.
Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable
access time (tCE) is the delay from the stable addresses and stable CE# to valid data at the output pins. The
output enable access time is the delay from the falling edge of OE# to valid data at the output pins (assuming
the addresses are stable for at least tACC–tOE time).

Note
Operation is shown for the 32-bit data bus. For the 16-bit data bus, A-1 is required.
