Peripheral NANDEdit
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.
DescriptionEdit
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 mappingEdit
The Pin mapping is described in the Pinout table section
