Write waveform 2 (CE1 and CE2 controlled)10,11,12
AC test conditions
Notes
1
During VCC power-up, a pull-up resistor to VCC on CE1 is required to meet ISB specification.
2
This parameter is sampled and not 100% tested.
3
For test conditions, see AC Test Conditions, Figures A and B.
4tCLZ 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 100% tested.
6WE is high for read cycle.
7CE1 and OE are low and CE2 is high for read cycle.
8
Address valid prior to or coincident with CE1 transition Low.
9
All read cycle timings are referenced from the last valid address to the first transitioning address.
10 N/A
11 All write cycle timings are referenced from the last valid address to the first transitioning address.
12 CE1 and CE2 have identical timing.
13 C = 30 pF, except all high Z and low Z parameters where C = 5 pF.
