Notes:
1. Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS840E32T-7.5T.
2. 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.
3. TA = C = Commercial Temperature Range. TA = I = Industrial Temperature Range.
4.
GSI offers other versions this type of device in many different configurations and with a variety of different features, only some of which
are covered in this data sheet. See the GSI Technology web site for a complete listing of current offerings.
