9.3 NAND Flash Memory
The Microchip SAMA7D65 System-On-Module Series embeds an SLC NAND Flash memory supported through its External Bus Interface (EBI) controller with different memory sizes depending on the part number.
The System-On-Module implements the following reference, available in a VFBGA-63 package:
- 8-Gbit memory size
- Macronix MX60LF8G28AD-XKI
The software must be adapted to recognize the relevant NAND Flash manufacturer. For details on how to build Linux® software, refer to www.linux4microchip.com/.
The NAND_CS_IN signal (pin 49) is accessible externally and can be uncoupled from the NAND_CS_PA13 signal (pin 50) so that the boot can be unselected from the NAND Flash memory during debug phases.
