1.6 Important Note
In this document, wherever i.MX 8M Mini or i.MX 8M Nano SoC signal name is mentioned, it is followed as per below
format for easy understanding.
•If CPU pin doesn’t have multiplexing option or used for dedicated functionality then the signal name is
mentioned as functionality name.
“Functionality Name”
Example: ENET_TXC
In this signal, ENET_TXC pad is used for same functionality.
•If CPU pin selected as GPIO function, then the signal name is mentioned as
“Functionality Description (GPIO Number)”
Example: BCONFIG_0(GPIO1_9)
In this signal, BCONFIG_0 is the GPIO functionality which we are using and GPIO1_9 is the GPIO number.
Note: The above naming is not applicable for other signals which are not connected to CPU.

1. There are six configurations of i.MX 8M Mini or i.MX 8M Nano SoC supported by NXP, hence in this document i.MX
8M Mini or i.MX 8M NanoQ/QL/D/DL/S/SLis used to represent either of one based on SBC Part Number.
2. The i.MX 8M Mini and i.MX 8M Nano SoC can support up to 8GB RAM but considering the available LPDDR4 Chips,
i.MX 8M Nano SBC can support up to 2GB RAM.
3. Memory Size will differ based on iWave’s SBC Product Part Number.
4. PCIe is not supported in i.MX 8M Nano SoC.
5. Since USB2 is NC in i.MX 8M Nano SoC, USB2.0 lines are supported through a switch.
6. Either HDMI or LVDS can be supported through MIPI_DSI to LVDS/HDMI Bridge. By default, HDMI display is
supported.
7. The i.MX 8M Mini or i.MX 8M Nano SBC can support wide range input power from 7V to 24V. By default, it is
designed to support 12V.

2.4 PMIC
i.MX 8M Mini or i.MX 8M Nano Pico ITX SBC uses Rohm’s BD71847AMWV on-board PMIC for Power management of
i.MX 8M Mini or i.MX 8M Nano SBCs. The BD71847AMWV is a Power Management Integrated Circuit (PMIC) designed
specifically for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M Mini.
The BD71847AMWV features six high efficiency buck converters and six linear regulators (LDOs) for powering the
processor, memory and miscellaneous peripherals. Built-in one-time programmable memory stores key start up
configurations, drastically reducing external components typically used to set output voltage and sequence of external
regulators. Regulator parameters are adjustable through I2C1 after start up offering flexibility for different system
states. The BD71847AMWV(U12) comes in 56pin QFN Package and placed on top side of SBC.

2.5 Memory
2.5.1 LPDDR4 RAM
The i.MX 8M Mini or i.MX 8M Nano Pico ITX SBC supports 1GB RAM using 32bit LPDDR4 IC for i.MX 8M Mini and 1GB
RAM using 16bit LPDDR4 IC for i.MX 8M Nano connected to DDR controller of SoC to support LPDDR4 clock up to 1.5
GHz in Mini and up to 1.6GHz in Nano. The LPDDR4 IC(U14) placed on Top side of the SBC. The RAM size can be
expandable up to maximum of 8GB in i.MX 8M Mini and up to 2GB in i.MX 8M Nano. To customize the LPDDR4 memory
size, contact iWave.
2.5.2 eMMC Flash
The i.MX 8M Mini or i.MX 8M Nano Pico ITX SBC supports 8GB eMMC as default boot device and storage device. This
is connected to eMMC0 version 5.1v controller of the i.MX 8M Mini or i.MX 8M Nano SoC and operates at 1.8V (I/O
supply) and 3.3V (NAND core supply) Voltage levels.
The eMMC flash (U8) memory is physically located on top side of the SBC. The memory size of the eMMC Flash can be
customised based on the requirement by contacting iWave Support Team.
2.5.3 Micro SD Connector
The i.MX 8M Mini or i.MX 8M Nano Pico ITX SBC supports Micro SD slot which can be used to connect Micro SD card
as optional boot device as well as Mass storage device. Micro SD card connector (J20) is directly connected to the
USDHC2 controller of the i.MX 8M Mini or i.MX 8M Nano SoC. The main power to Micro SD Card Connector is 3.3
Voltage. The i.MX 8M Mini or i.MX 8M Nano SBC supports configurable I/O voltage levels (3.3V/1.8V) for USDHC2 lines
through GPIO1_4. The voltage is 3.3V by default and will switch to 1.8V when high speed card is used by making use
of GPIO1_4 connected to PMIC. The Micro SD Connector is physically located on bottom side of the i.MX 8M Mini or
i.MX 8M Nano Pico ITX SBC as shown below.
