Notes
1 During VCC power-up, a pull-up resistor to VCC on CS is required to meet ISB specification.
2 This parameter is sampled, but not 100% tested.
3 For test conditions, see AC Test Conditions.
4 tCLZ and tCHZ are specified with CL = 5pF as in Figure C. Transition is measured ±500 mV from steady-state voltage.
5 This parameter is guaranteed, but not tested.
6 WE is HIGH for read cycle.
7 CS and OE are LOW for read cycle.
8 Address valid prior to or coincident with CS transition LOW.
9 All read cycle timings are referenced from the last valid address to the first transitioning address.
10 CS or WE must be HIGH during address transitions. Either CS or WE asserting high terminates a write cycle.
11 All write cycle timings are referenced from the last valid address to the first transitioning address.
12 N/A.
13 1.2V data retention applies to commercial and industrial temperature range operations.
14 C = 30pF, except at high Z and low Z parameters, where C = 5pF.
