AC test conditions
Notes
1During VCC power-up, a pull-up resistor to VCC on CE is required to meet ISB specification.
2
For test conditions, see AC Test Conditions, Figures A, B.
3
These parameters are specified with CL = 5pF, as in Figures B. Transition is measured
±500mV from steady-state voltage.
4
This parameter is guaranteed, but not tested.
5
WE is High for read cycle.
6
CE and OE are Low for read cycle.
7
Address valid prior to or coincident with CE transition Low.
8
All read cycle timings are referenced from the last valid address to the first transitioning address.
9
All write cycle timings are referenced from the last valid address to the first transitioning address.
10 C=30pF, except on High Z and Low Z parameters, where C=5pF.
