This is an Obsolete Application Note
The document AN41299 - Interfacing Cypress CY3686 DVK to NAND Flash Memory with Four Chip Selects has been marked as obsolete. The obsolete version of this application note is still available with the below description but may not be complete or valid any longer. If you have any questions or require support in regards to the below application note content, please click here and create a technical support case.

The Samsung K9NCG08U5M (64 Gbit) and K9WBG08U5M (32 Gbit) are NAND flash memory devices in a 48-pin TSOP stacked package. This application note considers these chips as examples to understand the interface between the CY3686 development kit (DVK) and NAND flash devices with four chip select requirement. K9NCG08U5M and K9WBG08U5M consist of four separate memory dies of 16 Gb and 8 Gb, respectively. Each of these devices requires an individual Chip Enable (CE) input and an individual Ready or Busy (R/B) output. The Cypress CY3686 DVK board contains eight separate 48-pin TSOP sockets. These sockets, however, only accept single package chips and have the connections for only two CE inputs and two R/B outputs.
