NOTES

1Measured using internal R

FB A and RFB B.

Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed

for standard product dice. Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing.
