Description

RY/BY#

Output - open

drain

Ready/Busy. Indicates whether an Embedded Algorithm is in progress or complete. At VIL, the device is

actively engaged in an Embedded Algorithm such as erasing or programming. At High-Z, the device is

ready for read or a new command write - requires external pull-up resistor to detect the High-Z state.

Multiple devices may have their RY/BY# outputs tied together to detect when all devices are ready.

No Connect

Not Connected internally. The pin/ball location may be used in Printed Circuit Board (PCB) as part of a

routing channel.

RFU

No Connect

Reserved for Future Use. Not currently connected internally but the pin/ball location should be left

unconnected and unused by PCB routing channel for future compatibility. The pin/ball may be used by a

signal in the future.

DNU

Reserved

Do Not Use. Reserved for use by the OCM. The pin/all is connected internally. The input has an internal pull

down resistance to VSS. The pin/ball can be left open or tied to VSS on the PCB.
