9.3 NAND Flash Memory

The SAM9X60D1G-I/LZB System-On-Module embeds a 4-Gbit SLC NAND Flash memory supported through its External Bus Interface controller.

The System-On-Module implements one of the following references to provide a 4-Gbit memory space:
  • MX30LF4G28AD-XKI in VFBGA-63 package
  • MT29F4G08ABAFAH4-IT:F in VFBGA-63 package
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).

The software must be adapted to recognize the relevant NAND Flash manufacturer. Microchip Linux distribution supports all references. For details on how to build Linux software, refer to www.linux4microchip.com/.

The NAND_NCS_IN signal (pin 11) is accessible externally and can be uncoupled from the NAND_NCS_OUT signal (pin 12) so that the boot can be unselected from the NAND Flash memory during debug phases.
