P. 6 of 9
Write waveform 2 (CE controlled)10,11
AC test conditions
Notes
1
During VCC power-up, a pull-up resistor to VCC on CE is required to meet ISB specification.
2
This parameter is sampled, but not 100% tested.
3
For test conditions, see AC Test Conditions, Figures A and B.
4tCLZ and tCHZ are specified with CL = 5 pF, as in Figure B. Transition is measured ±500 mV from steady-state voltage.
5
This parameter is guaranteed, but not 100% tested.
6
WE is high for read cycle.
7
CE and OE are low for read cycle.
8
Address is valid prior to or coincident with CE 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 N/A.
13 C = 30 pF, except all high Z and low Z parameters where C = 5 pF.
