No Connect

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

Reserved

Do Not Use. A device internal signal may be connected to the package connector. The

connection may be used by Cypress 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

connect any host system signal to these connections.

RFU

No Connect

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.
