S25FL064LABNFI043 Center Slug Pad

[DeLe_4078256]

The datasheet for S25FL064L indicates that the S25FL064LABNFI043 option (USON) has an exposed center slug pad. Neither the connectivity diagrams nor signal descriptions indicate the presence or connectivity of this center slug pad, but the notes for the pad (002-12878 Rev. *F pp 138) suggest that this pad is to be used for heat sink purposes.

Is this pad NC, DNU, or is there an expected connection (eg. ground)?

Hi Devron,

Thank you for contacting Cypress Semiconductor.

The exposed pad does not have any electrical significance, and is not internally connected to the die. For more information, please go through the following KBA - Exposed Pad Connection in WSON Package of Cypress Flash Devices – KBA219703 .
