Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS840E32AT-8T.
The speed column indicates the cycle frequency (MHz) of the device in Pipelined mode and the latency (ns) in Flow Through mode. Each
device is Pipeline/Flow through mode-selectable by the user.
