Page 14: Electronics
On the MBa8MPxL the standard interfaces like USB, Ethernet, etc., provided by the TQMa8MPxL are routed to industry standard connectors. All other relevant signals and buses provided by the TQMa8MPxL are routed to 50 mil pin headers on the MBa8MPxL. -
Page 15: I 2 C Devices, Address Mapping
All I2C buses provided by the TQMa8MPxL have a 3.3 V level. In order to be able to connect 1.8 V components as well, two level converters are used on the MBa8MPxL. One is permanently connected to I2C4, the second can be varied in its connection, but uses I2C2 by default. -
Page 16: Rtc Backup
RTC backup In case of power failure or power down, a lithium battery type CR2032 on the MBa8MPxL supplies the RTC on the TQMa8MPxL, which can be supplied with 2.1 V to 3.7 V, typical 3.0 V. The TQMa8MPxL features an i.MX 8M Plus-internal RTC or a discrete RTC PCF85063A. -
Page 17: Reset
The RESET_OUT# signal of the TQMa8MPxL is available on the MBa8MPxL. A red LED (V59) on the MBa8MPxL indicates a reset condition; see Table 26. On the MBa8MPxL a partial reset of the TQMa8MPxL is possible, e.g. with signals PMIC_WDOG_IN# and RESET_IN#. TQMa8MPxL... -
Page 18: Power Supply
Power supply At X13, the MBa8MPxL has to be supplied with 24 V +10 % / –33 % (16 V to 26.4 V). All other voltages required on the MBa8MPxL are derived from the supply voltage. 5 V (2.2 A), 3.3 V (1.75 A) and 1.8 V (0.75 A) are available at pin headers X61 and X63. It must be ensured that the permissible limit values of the input circuitry are not exceeded. -
Page 19: Communication Interfaces
3.3.1 Ethernet 1000 Base-T (RGMII) The i.MX 8M Plus CPU has two independent RGMII interfaces. On the MBa8MPxL both interfaces are used to provide two Gigabit Ethernet ports by means of two DP83867 Ethernet PHYs. The PHY has boot straps to start with adjustable default values. Some boot straps can be customized with placement options. -
Page 20: Sd Card Interface
3.3.2 SD card interface The MBa8MPxL 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. Since this voltage is controlled by SD_RESET#, the microSD card is automatically reset in case of a Reset. -
Page 21: Usb 3.0 Hub
USB Host 1 & 2 of the TUSB8041 are connected to a Dual USB 3.0 Type A socket (X36) on the MBa8MPxL. USB Host 3 is routed to the PCIe M.2 connector X48, USB Host 4 is routed to the LVDS-CMD connector X7 on the MBa8MPxL. -
Page 22: Pcie M.2
For PCIe, the connection of a plug-in card in the M.2 form factor is provided. The M.2 standard defines different codings for the connector, an M.2 slot with "A+E" coding is used on the MBa8MPxL. M.2 modules are available in different form factors. The MBa8MPxL supports the common 2230 form factor. -

Page 24: Mipi Dsi / Displayport
The TQMa8MPxL MIPI DSI interface, consisting of a differential clock signal and four differential data lines, is routed on the MBa8MPxL to DisplayPort connector X65 via a Toshiba TC9595XBG DSI-to-DisplayPort bridge. The bridge supports DisplayPort 1.1a standard and thus resolutions of 1920x1200 at 60 FPS. -
Page 25: Mipi Csi
If a use as GPIO is required, this can be made possible by equipping 0 Ω resistors. The I C buses operate at 1.8 V and are connected to I2C4 via a level shifter on the MBa8MPxL. CSI0 can optionally be connected to another I C bus to avoid address conflicts. -
Page 26: Lvds
The i.MX 8M Plus offers an LVDS controller with a dual LVDS interface. Each of the interfaces uses four differential lanes. On the MBa8MPxL there is one interface for connecting single or dual LVDS. In addition, two GPIO (BLT_EN, RESET#), a PWR_EN and a PWM signal are provided. -
Page 27: Hdmi
3.3.10 HDMI The HDMI_TX interface of the TQMa8MPxL is provided on the MBa8MPxL on an HDMI connector. Between TQMa8MPxL and HDMI socket is a "HDMI signal conditioning chip", which converts the levels and provides ESD protection.
