V
CC
3.0 volt-only single power supply (see
for speed options and voltage
supply tolerances)
V
SS
Device Ground
NC
Not Connected. No device internal signal is connected to the package connector nor is there any future plan to use the
connector for a signal. The connection may safely be used for routing space for a signal on a Printed Circuit Board
(PCB).
DNU
Do Not Use. A device internal signal may be connected to the package connector. The connection may be used by
Spansion for test or other purposes and is not intended for connection to any host system signal. Any DNU signal
related function will be inactive when the signal is at V
IL
. The signal has an internal pull-down resistor and may be left
unconnected in the host system or may be tied to V
SS
. Do not use these connections for PCB signal routing channels.
Do not connect any host system signal to these connections.
RFU
Reserved for Future Use. No device internal signal is currently connected to the package connector but there is
potential future use for the connector for a signal. It is recommended to not use RFU connectors for PCB routing
channels so that the PCB may take advantage of future enhanced features in compatible footprint devices.
