READ
The WE32K32-XXX stores data at the memory location
determined by the address pins. When CS# and OE#
are low and WE# is high, this data is present on the
outputs. When CS# and OE# are high, the outputs are in
a high impedance state. This 2 line control prevents bus
contention.
FIGURE 6 – READ WAVEFORMS
NOTES:
1. OE# may be delayed up to tACS - tOE after the falling edge of CS# without impact on tOE or by tACC - tOE after
an address change without impact on tACC.
2. tCHZ, tOHZ are specied from OE# or CS# whichever occurs rst (CL = 5pF).
3. All I/O transitions are measured ±200 mV from steady state with loading as specied in "Load Test Circuits."
