Appendix A Capacitor Specifications - SanDisk INAND Product Manual

Revision 3.1
Appendix A
A.1 SanDisk iNAND Operation
In order for iNAND to operate at 3V, an external capacitor must be added to the FCAP
(G8) pin and grounded to VSS.
instructions are detailed below.
The trace requirements from the FCAP (G8) pin to the capacitor are as follows:
•
Resistance: <2 ohm
•
Inductance: <5 nH
The capacitor requirements are as follows:
•
Capacitance: >=2.2uF
•
Voltage: >=6.3 V
•
Dielectric: X7R or X5R
C1=C3>=2.2uF
C2=C4<=100nF
C1, C2: X7R or XR5
