Currently four i.MX 8M Plus derivatives are supported: 1) i.MX 8M Plus Dual (Dual Cortex®-A53) 2) i.MX 8M Plus Quad 4 Lite (Quad Cortex®-A53) 3) i.MX 8M Plus Quad 6 Video (Quad Cortex®-A53) 4) i.MX 8M Plus Quad 8 ML/AI (Quad Cortex®-A53) 2.1 MBa8MP-RAS314 block diagram µSD-Card SDHC Micro-USB Bus bridge TQMa8MPxL (LGA module) uSDHC #2 USB3.0 #1 RAM NOR Flash E-MMC UART #3/4 USB3.0 #2 USB USB USB DEV 4x USB3.0 USB Hub optional Touch (LVDS) GPIO header 1 x 3,5 mm jack Camera interface I2C Audio Codec MIPI-CSI I2C #3/5 ECSPI #3 uSDHC #1 UART #1 GPIO PCIe UART #2 PCIe Data HDMI HDMI HDMI signal conditioning LVDS LVDS I2C #4 MIPI DSI DSI SAI #5 MIPI CSI1 ENET TSN RGMII ENET QOS RGMII Gigabit ETH PHY Gigabit ETH PHY WiFi HDMI LVDS Display interface Ethernet 10/100/1k Ethernet 10/100/1k Power IN 12 V DC/DC Module 5 V Power Rails Boot Figure 1: Block diagram MBa8MP-RAS314 Boot Config Preliminary User's Manual l MBa8MP-RAS314 UM 0003 l © 2024, TQ-Systems GmbH Page 10 2.2 MBa8MP-RAS314 interfaces, overview The following interfaces/functions and user interfaces are available on the MBa8MP-RAS314: Table 2: Data interfaces Interface Audio Camera interface Display Interface Eth. 1000 Base-T GPIO HDMI JTAG LVDS CMD LVDS Data SD card USB 3.0 USB Debug USB 3.0 DEV WiFi Connector Type X3 1 × 3.5 mm jack X5 1-1734248-5, TE Connectivity X6 1-1734248-5, TE Connectivity X15, X16 RJ45 X1 X9 X17 X8 X7 X2 X12, X13 X4 X14 X10, X11 SL-22-124-40-G, 2,54 mm HDMI 10-pin, 50 mil pin header 14-pin, DF19G 20-pin, DF19G Micro-SD Stacked Type A Micro USB AB Micro USB Type B U.FL-R-SMT-1(10) Remark MIC (mono), headphone (stereo) Gigabit PHY DP83867 and socket with integrated transformers Connected to IO bank (GPIO) JTAG ZIF connector ZIF connector USDHC2, optional boot source UART3, UART4 USB 3.0 Device or Serial Downloader The MBa8MP-RAS314 provides the following diagnostic and user interfaces: Table 3: Diagnostic and user interfaces Interface Reference Status LEDs S1 Power / Reset S2 S3 Boot-Mode S4 Component 1 × Red LED 5 × Green LED 1 × Green LED 1 × Orange LED 1 x Green LED 1 x Green LED 4 x Green LED 4 x Green LED 3 × Pushbutton 1 × 4-fold DIP switch Remark Reset Voltages on MBa8MP-RAS314 General purpose LED General purpose LED SD-Card Debug-USB USB V_VBUS30_H1...H4 Ethernet link / activity Reset PMIC reset CPU-ON/OFF Boot Device selection Preliminary User's Manual l MBa8MP-RAS314 UM 0003 l © 2024, TQ-Systems GmbH Page 11 3. ELECTRONICS 3.1 MBa8MP-RAS314 functional groups The following chapters describe the interfaces of the MBa8MP-RAS314 in connection with a TQMa8MPxL. 3.1.1 TQMa8MPxL overview The MBa8MP-RAS314 provides all power supplies and configurations required for the operation of the TQMa8MPxL. The TQMa8MPxL is the central system on the MBa8MP-RAS314. It provides LPDDR4 SDRAM, eMMC, NOR flash, RTC, an EEPROM, power supply and power management functionality. All TQMa8MPxL internal voltages are derived from the 5 V supply voltage. All functionally relevant pins of the i.MX 8M Plus are routed to the TQMa8MPxL connectors or LGA pads. This enables to use the TQMa8MPxL with all the freedom that comes with a customer-specific design-in solution. Further information can be found in the TQMa8MPxL User's Manual. On the MBa8MP-RAS314 the standard interfaces like USB, Ethernet, etc., provided by the TQMa8MPxL are routed to industry standard connectors. Most other relevant signals and buses provided by the TQMa8MPxL are routed to 100 mil pin headers on the MBa8MP-RAS314. The boot behaviour of the TQMa8MPxL can be controlled. The boot mode configuration is set with a DIP switch on the MBa8MPRAS314.

All other voltages required on the MBa8MPRAS314 are derived from this supply voltage. The MBa8MP-RAS314 has a theoretical maximum power consumption of approx. 42 W at its 12 V supply connection. This corresponds to a maximum typical current of 3.5 A at 12 V. The power supply unit used must be selected accordingly. In most applications, however, the power consumption will be significantly lower and the MBa8MP-RAS314 including TQMa8MPxL consumes approx. 5 W to 6 W when the i.MX 8M Plus operates at 100 % load. Most of the theoretically possible power consumption results from the standard-compliant supply of the USB and LVDS interfaces, as well as from the power available at the pin headers. It must be ensured that the permissible limit values of the input circuitry are not exceeded.

The height without heatspreader and heatsink is approximately 20.5 mm. The MBa8MP-RAS314 including TQMa8MPxL weighs approximately 95 grams. Figure 17: Dimensions MBa8MP-RAS314 5.2 Embedding in the overall system The MBa8MP-RAS314 serves as a design base for customer products, as well as a platform to support during development. 5.3 Thermal management The combination of MBa8MP-RAS314 and TQMa8MPxL has a power consumption of approximately TBD watts. Further power consumption occurs mainly at externally connected devices. Attention: TQMa8MPxL heat dissipation The i.MX 8M Plus belongs to a performance category in which a cooling system is essential. It is the user's sole responsibility to define a suitable heat sink (weight and mounting position) depending on the specific mode of operation (e.g., dependence on clock frequency, stack height, airflow, and software). Particularly the tolerance chain (PCB thickness, board warpage, BGA balls, BGA package, thermal pad, heatsink) as well as the maximum pressure on the TQMa8MPxL must be taken into consideration when connecting the heat sink. The TQMa8MPxL is not the highest component. Inadequate cooling connections can lead to overheating of the TQMa8MPxL or the MBa8MP-RAS314 and thus malfunction, deterioration or destruction.

Preliminary User's Manual l MBa8MP-RAS314 UM 0003 l © 2024, TQ-Systems GmbH Page 31 6.7 Warranty TQ-Systems GmbH warrants that the product, when used in accordance with the contract, fulfills the respective contractually agreed specifications and functionalities and corresponds to the recognized state of the art. The warranty is limited to material, manufacturing and processing defects. The manufacturer's liability is void in the following cases: · Original parts have been replaced by non-original parts. · Improper installation, commissioning or repairs. · Improper installation, commissioning or repair due to lack of special equipment. · Incorrect operation · Improper handling · Use of force · Normal wear and tear 7. CLIMATIC AND OPERATIONAL CONDITIONS In general reliable operation is given when the following conditions are met: Table 21: Climatic and operational conditions MBa8MP-RAS314 Parameter Ambient temperature Storage temperature Relative humidity (operation / storing) Range TBD TBD TBD Remark Not condensing Attention: TQMa8MPxL heat dissipation The i.MX 8M Plus belongs to a performance category in which a cooling system is essential. It is the user's sole responsibility to define a suitable heat sink (weight and mounting position) depending on the specific mode of operation (e.g., dependence on clock frequency, stack height, airflow, and software). Particularly the tolerance chain (PCB thickness, board warpage, BGA balls, BGA package, thermal pad, heatsink) as well as the maximum pressure on the TQMa8MPxL must be taken into consideration when connecting the heat sink. The TQMa8MPxL is not the highest component. Inadequate cooling connections can lead to overheating of the TQMa8MPxL or the MBa8MP-RAS314 and thus malfunction, deterioration or destruction. 7.1 Protection against external effects Protection class IP00 was defined for the MBa8MP-RAS314. There is no protection against foreign objects, touch or humidity. 7.2 Reliability and service life No detailed MTBF calculation has been done for the MBa8MP-RAS314. The MBa8MP-RAS314 is designed to be insensitive to vibration and impact. Preliminary User's Manual l MBa8MP-RAS314 UM 0003 l © 2024, TQ-Systems GmbH Page 32 8. ENVIRONMENT PROTECTION 8.1 RoHS The MBa8MP-RAS314 is manufactured RoHS compliant. All components, assemblies and soldering processes are RoHS compliant. 8.2 WEEE® The final distributor is responsible for compliance with the WEEE® regulation. Within the scope of the technical possibilities, the MBa8MP-RAS314 was designed to be recyclable and easy to repair. 8.3 REACH® The EU-chemical regulation 1907/2006 (REACH® regulation) stands for registration, evaluation, certification and restriction of substances SVHC (Substances of very high concern, e.g., carcinogen, mutagen and/or persistent, bio accumulative and toxic). Within the scope of this juridical liability, TQ-Systems GmbH meets the information duty within the supply chain with regard to the SVHC substances, insofar as suppliers inform TQ-Systems GmbH accordingly. 8.4 EuP The Ecodesign Directive, also Energy using Products (EuP), is applicable to products for the end user with an annual quantity >200,000. The MBa8MP-RAS314 must therefore always be seen in conjunction with the complete device. The available standby and sleep modes of the components on the MBa8MP-RAS314 enable compliance with EuP requirements for the MBa8MP-RAS314. 8.5 Statement on California Proposition 65 California Proposition 65, formerly known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The proposition helps protect the state's drinking water sources from contamination by approximately 1,000 chemicals known to cause cancer, birth defects, or other reproductive harm ("Proposition 65 Substances") and requires businesses to inform Californians about exposure to Proposition 65 Substances. The TQ device or product is not designed or manufactured or distributed as consumer product or for any contact with endconsumers. Consumer products are defined as products intended for a consumer's personal use, consumption, or enjoyment. Therefore, our products or devices are not subject to this regulation and no warning label is required on the assembly. Individual components of the assembly may contain substances that may require a warning under California Proposition 65. However, it should be noted that the Intended Use of our products will not result in the release of these substances or direct human contact with these substances. Therefore you must take care through your product design that consumers cannot touch the product at all and specify that issue in your own product related documentation. TQ reserves the right to update and modify this notice as it deems necessary or appropriate. 8.6 Packaging The MBa8MP-RAS314 is delivered in reusable packaging. 8.7 Batteries The MBa8MP-RAS314 does not require a battery and therefore does not use batteries containing mercury (Hg), cadmium (Cd) or lead (Pb). 8.8 Other entries By environmentally friendly processes, production equipment and products, we contribute to the protection of our environment. To be able to reuse the MBa8MP-RAS314, it is produced in such a way (a modular construction) that it can be easily repaired and disassembled. The energy consumption of the MBa8MP-RAS314 is minimised by suitable measures. Because currently there is still no technical equivalent alternative for printed circuit boards with bromine-containing flame protection (FR-4 material), such printed circuit boards are still used. No use of PCB containing capacitors and transformers (polychlorinated biphenyls). These points are an essential part of the following laws: · The law to encourage the circular flow economy and assurance of the environmentally acceptable removal of waste as at 27.9.94 (Source of information: BGBl I 1994, 2705) · Regulation with respect to the utilization and proof removal as at 1.9.96 (Source of information: BGBl I 1996, 1382, (1997, 2860)) · Regulation with respect to the avoidance and utilization of packaging waste as at 21.8.98 (Source of information: BGBl I 1998, 2379) · Regulation with respect to the European Waste Directory as at 1.12.01 (Source of information: BGBl I 2001, 3379) This information is to be seen as notes. Tests or certifications were not carried out in this respect. Preliminary User's Manual l MBa8MP-RAS314 UM 0003 l © 2024, TQ-Systems GmbH 9.
