9.3 NAND Flash Memory

The Microchip SAM9X75 System-On-Module Series embeds an SLC NAND Flash memory supported through its External Bus Interface controller with different memory sizes depending on the part number.

The System-On-Module implements one of the following references, depending on the memory space. All are available in a VFBGA-63 package.
  • 2-Gbit memory size(1)(2)
    • Macronix MX30LF2G28AD-XKI
    • Micron MT29F2G08ABAEAH4-IT:G
  • 4-Gbit memory size(1)(2)
    • Macronix MX30LF4G28AD-XKI
    • Micron MT29F4G08ABAFAH4-IT:F
Note:
  1. Either one of the above references can be mounted on the Microchip SAM9X75 System-On-Module Series.
  2. Read/write speed may vary depending on the NAND Flash reference fitted to the module.

For more information about NAND Flash memories, refer to the relevant data sheets (see Reference Documents).

Microchip Linux distribution supports all references. For details on how to build Linux software, refer to www.linux4microchip.com.

NAND_CS_IN (pin 17) is accessible externally and can be uncoupled from NAND_CS_PD4 (pin 18) so that the boot can be unselected from the NAND Flash memory during debug phases.
