Peripheral NAND[edit | edit source]

MITO 8M SOM provides a NAND interface available for an external memory device connection.

The availability of this interface is related to the SOM mounting option:

  • on NAND on board version, the NAND interface is internally connected, and the SD1 interface is routed externally the SOM
  • on eMMC on board version, the SD1 interface is internally connected, and the NAND interface is routed externally the SOM

See Pin mapping tables for connection details.

Description[edit | edit source]

The NAND interface available on MITO 8M is based on iMX8M SoC.

The NAND Flash controller supports the following standards and features:

  • 8-bit NAND FLASH, up to 4 devices supported by 4 chip-selects and 1 ganged ready/busy
  • ONFI 2.x complaint, synchronous clock rate of up to 100 MHz with data rate of up to 200 MB/s
  • Support ONFI NAND for Micron and Hynix and Toggle NAND for Toshiba and Samsung
  • BCH62 for ECC, up to 200MB/s

Pin mapping[edit | edit source]

The Pin mapping is described in the Pinout table section
