Page 7: Tips On Safety
Handling and ESD tips General handling of your TQ-products The TQ-product may only be used and serviced by certified personnel who have taken note of the information, the safety regulations in this document and all related rules and regulations. A general rule is: do not touch the TQ-product during operation. This is especially important when switching on, changing jumper settings or connecting other devices without ensuring beforehand that the power supply of the system has been switched off. -
Page 8: Naming Of Signals
User's Manual l MBa8Xx UM 0100 l © 2020, TQ-Systems GmbH Page 3 Naming of signals A hash mark (#) at the end of the signal name indicates a low-active signal. Example: RESET# If a signal can switch between two functions and if this is noted in the name of the signal, the low-active function is marked with a hash mark and shown at the end. -

User's Manual l MBa8Xx UM 0100 l © 2020, TQ-Systems GmbH Page 11 Boot Mode configuration The Boot Mode of the i.MX 8X is set with signals BOOT_MODE[3:0], which can be set with the 4-fold DIP switch S1. The MBa8Xx supports the following TQMa8Xx boot sources. -
Page 17: I 2 C Devices
Depending on the application and software load, the number of I C devices used can limit the data throughput or block the bus. For this reason, the devices used on the MBa8Xx can be optionally connected to the I2C2. This assembly option is described in the MBa8Xx schematics. - Page 18 Default I2C interface (continued) The following table shows the default I²C device addresses on the MBa8Xx and the TQMa8Xx. For some devices the address can be changed by assembly options. The options are described in detail in the given chapter.

Page 19: M4 I 2 C Interface
Both I²C lines M4_I2C_SCL and M4_I2C_SDA are provided with 2.2-kΩ pull-up resistors to 1.8 V on the MBa8Xx. To reduce the bus load on I2C1, the I²C devices on the MBa8Xx can be connected to the I2C2 bus. As shown in the following table, the configuration of the used I²C bus is determined by the resistors R371 to R374. -

Host is 900 mA. Since the TQMa8Xx only provides two USB interfaces and one of them is used as a debug interface on the MBa8Xx, the second USB interface of the TQMa8Xx is connected to a hub, which provides two additional, internally used USB 2.0 hosts in addition to the two USB 3.0 hosts described here. -

I/O voltage of 1.8 V since the supply voltage of the SD card is not power-cycled after a system reset on the MBa8Xx revision 02xx. This will be corrected on the MBa8Xx revision 03xx. Because of this behaviour, the host cannot reinitialize the SD card in SDR104 mode at boot time and communication problems may occur. -
Page 43: Mba8Xx Headers
Note: Observe power consumption with regard to the overall system The supply voltages (1.8 V, 12 V, etc.) provided at the MBa8Xx headers are not individually fused. Technically, an overload of the fuse at the 24 V supply input is therefore possible, see also chapter 3.10. - Page 44 User's Manual l MBa8Xx UM 0100 l © 2020, TQ-Systems GmbH Page 39 3.8.13 MBa8Xx headers (continued) Table 42: Pinout Header X4 Level Group Signal Signal Group Level 12 V Power V_12V V_3V3_MB Power Power V_5V V_1V8 Power 1.8 V...

Page 48: Power Supply
Voltage stabilization Attention: Voltages at headers The internal voltages (1.8 V, 12 V, etc.) provided at the MBa8Xx headers are not separately fused. Technically an overload of the fuse is therefore possible. The resulting total current consumption of the MBa8Xx should be kept below 4 A in total. - Page 49 24 V supply voltage Ground Figure 22 shows all voltages (rails) on the MBa8Xx, which are divided into three main paths consisting of two LM25119 and one TPS45335. These supply the largest loads. (TQMa8Xx, USB supply, 12 V display supply.) The design also allows power sequencing of all voltage levels used.

Page 52: Reset Structure
Figure 25 shows the reset structure on the MBa8Xx. In addition to the reset signals of the TQMa8Xx, the MBa8Xx also provides further software-controlled reset signals for individual function blocks, e.g. ENET reset for the Ethernet transceivers. These are implemented by GPIO signals and named accordingly in the respective chapters when applicable. -
Page 53: Software
The MBa8Xx has overall dimensions (length × width × height) of 170 × 170 × 27.1 mm³. The MBa8Xx has six 4.2 mm mounting holes for the housing, and three 2.7 mm mounting holes for a heat sink. The MBa8Xx weighs approximately 220 grams without TQMa8Xx. -
Page 54: Notes Of Treatment
Thermal management The greatest power dissipation on the MBa8Xx is caused by the voltage regulators. In addition, the TQMa8Xx is a heat source that acts indirectly on the MBa8Xx. Depending on the application, further power dissipation can occur, mainly at additional external loads on the pin headers on the MBa8Xx, the Mini PCIe slot, etc. - Page 55 TQMa8Xx must be taken into consideration when connecting the heat sink. The TQMa8Xx is not the highest component. Inadequate cooling connections can lead to overheating of the TQMa8Xx or the MBa8Xx and thus malfunction, deterioration or destruction.
