This Guide provides detailed information on the overall design and usage of the i.MX 8M Plus SMARC SOM from a
Hardware Systems perspective.
1.2 SMARC SOM Overview
The SMARC V2.1.1 (“Smart Mobility ARChitecture version 2.1.1”) is a versatile small form factor Computer Module
definition targeting application that require low power, low costs, and high performance. The Modules are used as
building blocks for portable and stationary embedded systems. The core SoC and support circuits, including DRAM,
boot flash, power sequencing, SoC power supplies, GbE, GNSS module (optional) and dual channel LVDS/ MIPI display
transmitter are concentrated on the Module. The Modules are used with application specific Carrier Boards that
implement other features such as audio CODECs, touch controllers, wireless devices, etc. The modular approach allows
scalability, fast time to market and upgradability while still maintaining low costs, low power and small physical size.
NXP’s i.MX 8M Plus SoC based SMARC System on Module is rich withi.MX 8M Plus features along with on SOM LPDDR4,
eMMC, Dual Ethernet PHY (onewith TSN support), USB2.0 Hub, Wi-Fi & BT module, GNSS module (optional) and comes
in compact 82mm x 50mm form factor. The Module PCB has 314 edge fingers that mate with a low profile 314 pin
0.5mm pitch right angle connector.

2. In Murata-1MW, Wi-Fi is supported by using SDIO interface, hence On SOM microSD will be an optional feature.
3. In default configuration, UART3 interface of i.MX 8M Plus is connected to SMARC Edge. If on SOM GNSS module is
used, UART3 will not be supported on SMARC Edge.
4. The i.MX 8M Plus supports MIPI_DSI and LVDS interface, but in SMARC Specification LVDS and MIPI_DSI interface
pins are multiplexed hence any one can be supported at a time based on SOM part Number. By default, MIPI DSI is
supported.
5. In default configuration, UART1 interface of i.MX 8M Plus is connected to on SOM Bluetooth module. One more
UART with CTS and RTS can be supported, if Bluetooth is not supported.

iW-RainboW-G40M SMARC SOM can support i.MX 8M Plus SoCs from NXP. The i.MX 8M Plus Family consists of three
processors: i.MX 8M Plus Quad, i.MX 8M Plus QuadLite & i.MX 8M Plus Dual. The Major Difference between i.MX 8M
Plus SoCs are:
•i.MX 8M Plus Quad : 4 x Cortex-A53, 1 x Cortex-M7, GPU, VPU, NPU, ISP & HiFi 4 Audio DSP
•i.MX 8M Plus QuadLite : 4 x Cortex-A53, 1 x Cortex-M7 & GPU
•i.MX 8M Plus Dual : 2 x Cortex-A53, 1 x Cortex-M7, GPU, VPU, NPU, ISP & HiFi 4 Audio DSP
The i.MX 8M Plus processors along with ARM core supports integrated NPU of 2.3 TOPs, OpenCL GPU, Image Signal
Processor, 1080p60 video encode and decode capable VPU, 3 x display controllers, multiple display output options,
including MIPI-DSI, HDMI 2.0, and LVDS. Memory interfaces supporting LPDDR4, FlexSPI, eMMC 5.1, SD 3.0 and a wide
range of peripheral I/Os such as PCIe 3.0 provide wide flexibility.
Figure 2: i.MX 8M Plus Block Diagram
Note: The i.MX 8M Plus processor offers numerous advanced features, please refer the latest i.MX 8M Plus Datasheet
& Reference Manual for Electrical characteristics and other information, which may be revised from time to time.

2.4 PCA9450C PMIC
The i.MX 8M Plus SMARC SOM uses one PCA9450C PMIC (U9) for SOM Power management. The PCA9450C features
six high efficiency step-down regulators and five linear regulators. It is a high-performance power management
integrated circuit (PMIC) that provides a highly programmable/configurable architecture with fully integrated power
devices and 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 high-speed I2C after start up offering flexibility for different system states. The PCA9450C PMIC
comes in 56pin 7x7 HVQFN Package and is placed on the Top side of the SOM.
2.5 Memory
2.5.1 LPDDR4 RAM
The i.MX 8M Plus SMARC SOM supports 2GB LPDDR4 RAM memory by default using the 32bit DDR_CH0 channel of
i.MX 8M Plus SoC to support LPDDR4 up to 2GHz speed. LPDDR4 part U14 is placed on Top side of the SOM. The RAM
size can be expandable up to maximum of 8GB. To customize the LPDDR4 memory size, contact iWave.
2.5.2 eMMC Flash
The i.MX 8M Plus SMARC SOM supports 16GB eMMC as default boot and storage device. This is directly connected to
uSDHC3 controller of the i.MX 8M Plus SoC and operates at 1.8V (I/O supply) and 3.3V (NAND core supply) Voltage
levels.
The eMMC flash memory (U30) is physically located on bottom side of the SMARC SOM. 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 (Optional)
The i.MX 8M Plus SMARC SOM optionally supports Micro SD connector which can be used to connect Micro SD card
as optional Mass storage device. Micro SD card connector (J5) is connected to the USDHC1 controller of the i.MX 8M
Plus SoC.
The main power to Micro SD Card Connector is 3.3 Voltage. The i.MX 8M Plus SMARC SOM supports configurable I/O
voltage levels for USDHC1 lines through GPIO1_IO03. If GPIO1_IO03 is set to low, then 3.3V IO level is selected for
uSDHC1 lines. If GPIO1_IO03 is set to high, then 1.8V IO level is selected for uSDHC1 lines. Micro SD Connector is
physically located on Top side of the i.MX 8M Plus SMARC SOM.

2.6 Network & Communiation
2.6.1 Wi-Fi and Bluetooth Interface
The i.MX 8M Plus SMARC SOM is integrated with Murata’s “LBEE5HY1MW” based Wi-Fi & Bluetooth module. The
LBEE5HY1MW module is a very high-performance module based on Cypress CYW43455 combo chipset which supports
WiFi IEEE 802.11a/b/g/n/ac + Bluetooth 5.0 BDR/EDR/LE standard.
The LBEE5HY1MW module utilizes highly optimized IEEE 802.11 Bluetooth coexistence protocols and supports single
stream 1x1 IEEE 802.11 a/b/g/n/ac mode providing up to 390Mbps. The LBEE5HY1MW module features small form
factor when integrating Power Amplifier (PA), Low Noise Amplifier (LNA), Transmit/Receive switch, Power
Management. The LBEE5HY1MW module need external Antenna and a 32.768 KHz clock for sleep operation.
The LBEE5HY1MW module (U19) provides Secure Digital Input Output (SDIO) for interfacing with the host controller
for Wi-Fi and UART interface for Bluetooth. The i.MX 8M Plus SMARC SOM uses processor’s UART1 interface for

Bluetooth and USDHC1 interface for Wi-Fi in default configuration. In i.MX 8M Plus SMARC SOM, antenna pin of Wi-Fi
& Bluetooth module is connected to J7 Connector.

Note: The operating temperature range of LBEE5HY1MW module is -30°C to 85°C .
2.6.2 GNSS Module (Optional)
The i.MX 8M Plus SMARC SOM can be optionally integrated with u-blox’s “NEO-M8Q-01A” based GNSS module. The
NEO-M8Q-01A module is built on the exceptional performance of the u-blox M8 GNSS engine in the industry proven
NEO form factor. It utilizes concurrent reception of up to three GNSS systems (GPS/Galileo together with BeiDou or
GLONASS) for more reliable positioning.
The NEO-M8Q-01A provides high sensitivity and minimal acquisition times while maintaining low system power. The
NEO-M8Q-01A combines a high level of robustness and integration capability along with flexible connectivity options
via USB, I2C, UART and SPI. The DDC (I2C compatible) interface provides connectivity and enables synergies with most
u-blox cellular modules.
The i.MX 8M Plus SMARC SOM makes use of the UART3 interface which is by default connected to the SMARC Edge
connector for communication between the Host and Device. The Antenna pin of the module can be connected to the
J6 Antenna connector through an Active or Passive Path as per the requirement.

2.6.3 RTC Controller
The i.MX 8M Plus SMARC SOM uses the On-SOM external RTC Controller “PCF85263” for Real time clock support. This
external RTC Controller is connected to i.MX 8M Plus SoC through I2C3 Interface and operates at 1.8V voltage level. In
SOM power off condition, this device will take 3V power from SMARC PCB Edge (VDD_RTC) coin cell power input (Pin
S147) and continues to update the current time. GPIO4_20 is connected to the Interrupt pin of the RTC controller,
which can be utilized for supporting wakeup and other features.
