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.

3.2

Power supply

At X18, the MBa8MP-RAS314 has to be supplied with 12 V +/-10 % (10.8 V to 13.2 V). 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.

SD card interface

The MBa8MP-RAS314 offers a microSD card slot that can also be used as boot source. All signals are directly connected to the USDHC2 interface of the i.MX 8M Plus.
The TQMa8MPxL voltage V_3V3_SD supplies the microSD card slot. This voltage is controlled by SD_RESET#, therefore the microSD card is automatically reset in case of a Reset. An external switch is not required. Signal USDHC2_CD# has a pull-up on the MBa8MP-RAS314. All data lines are ESD protected.
Standard, High and Extended capacity card types are supported. Default Speed, High Speed, and SD UHS-1 Speed Mode SDR104 with theoretically max.104 MB/s are supported. UHS-1 Speed Modes SDR12, SDR25, SDR50 and DDR50 are theoretically supported but not verified.
The TQMa8MPxL sets USDHC2 is to 1.8 V or 3.3 V automatically, depending on the transfer mode. The corresponding driver handles the changeover; it does not have to be done explicitly.
USDHC2_WP is not used and is terminated accordingly.

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.

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.
