We are designing a product using NorFlash（S29GL512N）. As our product has a higher reliability requirement, considering the EMC design, could you provide the internal function and structure of Pin NC ? In order to improve the ability of interference tolerance , how to deal with PIN NC, using pull-up resistor or pull-down resistor ?
Thank you for contacting Cypress Community.
The NC pin is not connected internally.
I would just like to inform you that S29GL512N device has been retired and is not recommended for new designs. You could try using our GL-T and GL-S devices for new designs.
