AC Test Conditions
Notes:
VZ is programmable from -2V to +7V.
IOL & IOH programmable from 0 to 16mA.
Tester Impedance Z0 = 75
.
VZ is typically the midpoint of VOH and VOL.
IOL & IOH
are adjusted to simulate a typical resistive load cir cuit.
ATE tester includes jig capacitance.
NOTES:
1. A21 must be held constant until WE# or CS# go high, whichever occurs first.
2. Typical value for t
WHWH1
is 7μs.
3. Typical value for t
is 1sec.
4. Typical value for Chip Erase Time is 32sec.
5. For Toggle and Data Polling.
