NOTES:
1. W is high for read cycle.
2. All timings are referenced from the last valid address to the first transitioning address.
3. Addresses valid prior to or coincident with E going low.
4. At any given voltage and temperature, tEHQZ(max) is less than tELQX(min), and tGHQZ(max) is less than tGLQX(min), both for a given device
and from device to device.
5. Transition is measured
±
500 mV from steady–state voltage with load of Figure 1B.
6. This parameter is sampled and not 100% tested.
7. Device is continuously selected (E = VIL, COE0 = VIL).
8. Applies to MPC2107.
