Processor and memory subsystemEdit

The heart of MITO 8M Mini module is composed by the following components:

  • i.MX8M Mini SoC application processor
  • Power supply unit
  • LPDDR4 memory bank
  • eMMC or NAND flash banks
  • Connectors:
    • 1 x 204 pins SO-DIMM edge connector with interfaces signals

This chapter shortly describes the main MITO 8M Mini components.

RAM memory bankEdit

LPDD4 SDRAM memory bank is composed by 1x 32-bit width chip. The following table reports the SDRAM specifications:

CPU connection Multi-mode DDR controller (MMDC)
Size max 4 GB
Width 32 bit
Speed 1600 MHz

eMMC flash bankEdit

On board main storage memory eMMC is connected to the SDIO1 interface and it can act as boot peripheral. The following table reports the eMMC flash specifications:

CPU connection SDIO1
Size min 4 GB
Size max 64 GB
Bootable Yes

NAND flash bankEdit

  Not available yet

Alternative option for main storage memory can be a 8-bit wide NAND flash connected to the CPU's Raw NAND flash controller. It can act as boot peripheral. The following table reports the NAND flash specifications:

CPU connection Raw NAND flash controller
Page size 512 byte, 2 kbyte or 4 kbyte
Size min 512MB
Size max 2GB
Width 8 bit
Chip select NAND_CE0
Bootable Yes

Memory mapEdit

For detailed information, please refer to chapter 2 “Memory Maps” of the i.MX8M Mini Applications Processor Reference Manual

Power supply unitEdit

MITO 8M Mini embeds all the elements required for powering the unit, therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the ranges power supply can assume as well as all other parameters.
