Device Ground
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).
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
unconnected in the host system or may be tied to V
Do not connect any host system signal to these connections.
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.
