AC CHARACTERISTICS – WRITE/ERASE/PROGRAM OPERATIONS,CS CONTROLLED
(VCC = 5.0V, VSS = 0V, TA = -55
°C to +125°C)
AC TEST CIRCUIT
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 circuit.
ATE tester includes jig capacitance.
