VDD_H and VDD_F Connections
SanDisk iNAND Product Manual
The iNAND has two power domains labeled: VDD_H and VDD_F. Currently both power
domains can be connected to the same 3.3V (nom) power supply. However, in order to
provide maximum flexibility and support low power operation in future iNAND devices,
the PCB should be designed as follows:
?
?
All VDD_F balls should be connected to a 3.3V supply
All VDD_H balls should have the option of being connected either to a 3.3V or 1.8V
supply
SanDisk recommends providing separate bypass capacitors for each power domain as
shown in Figure 1.
Note : Signal routing in the diagram is for illustration purposes only and the final routing
depends on your PCB layout. Also, for clarity, the diagram does not show the VSS
connection. All balls marked VSS should be connected to a ground (GND) plane.
