Notes:
1. WE is High for READ Cycle.
2. Device is continuously selected OE = VIL.
3. Address valid prior to or coincident with CE transition low.
4. CE = VIL.
5. Transition is measured ±500mV from steady state with CL = 5pF as shown in Figure 1b. This parameter is
guaranteed but not 100% tested.

WRITE CYCLE 2(1,6)
Note:
1.
WE must be high during address transitions.
2. The internal write time of the memory is defined by the overlap of CE active and WE low. All
signals must be active to initiate a write and any one signal can terminate a write by going
inactive. The data input setup and hold timing should be referenced to the second transition
edge of the signal that terminates the write.
3. TWR is measured from the earlier of CE or WE going high at the end of write cycle.
4. During this period, I/O pins are in the output state so that the input signals of opposite phase to
the outputs must not be applied.
5. If the CE low transition occurs simultaneously with the WE low transitions or after the WE
transition, outputs remain in a high impedance state.
6. OE is continuously low ( OE =VIL).
7. DOUT is the same phase of write data of this write cycle.
8. DOUT is the read data of next address.
9. If CE is low is high during this period, I/O pins are in the output state. Then the data input
signals of opposite phase to the outputs must not be applied to them.
10. Transition is measured ±200mV from steady state with CL=5pF.
11. tCW is measured from CE going low to the end of write.
