Interfaces and Functions

DC Power

Main power should be supplied using 12V DC power supply included in the evaluation kit. Adapters for European AC and US AC outlets are included. Connect the power supply to DC input jack J1.
ON/OFF switch SW1 switches main DC power. To turn on the system, switch SW1 to ON position.

Serial Console

To begin using serial console connect your host PC to the micro-USB connector P3 using the USB cable from the evaluation kit.

Serial Download Programming (SDP) port

USB SDP interface is available on micro-USB connector P21 located on the bottom side of the board under USB connector J3.
The SDP interface can be used for device recovery and firmware programming using the NXP UUU utility.
MCM-iMX93 can be forced into Serial Download Mode by shorting jumper E4.

Display and Touch-Screen

LVDS

LVDS signals are available on header P14.

MIPI-DSI

MIPI-DSI signals are available on header P12.

Touch-Screen

I2C-based touch-screen interface is available on header P13.

Connecting KD070HDTLA020 7" LVDS LCD panel

To connect Startec KD070HDTLA020 7" LCD panel use the EB-HDRLVDS adapter board (supplied with the LCD panel).
Connect the LCD data cable to adapter connector P7. Connect the LCD touch-panel cable to adapter connector P8.
Connect the adapter to LVDS and touch headers P14 and P13.

Audio

SB-MCMIMX93 features on-board Wolfson WM8962 audio codec.
Analog audio line output is routed to audio jack J6.
Analog audio line input is routed to audio jack J5.

USB

SB-MCMIMX93 features two USB2.0 ports that are derived from the i.MX93 USB sub-system:

  • Connectors J2 and J3 – USB type-A connectors

SD card

SB-MCMIMX93 supports SD card storage through micro-SD socket P4.
Pressing and holding the ALT-BOOT button SW2 during power-up or hardware reset forces MCM-iMX93 to boot firmware from the SD card.

mini-PCIe socket

SB-MCMIMX93 provides mini-PCI socket P8 that can be used for evaluation of USB-based modules such as 4G cellular modem.
NOTE: P8 socket does NOT provide PCI Express signals.

SIM card socket

uSIM card socket P7 is connected to mini-PCIe socket P8.
An active SIM card should be installed into P7 for operating a cellular modem in mini-PCIe socket P8.

Ethernet

SB-MCMIMX93 provides two Gigabit Ethernet port via RJ45 connectors P5 and P6.

WiFi and Bluetooth

SB-MCMIMX93 features an on-board Azurewave AW-CM276NF wireless module U6.
The module supports 802.11ac WiFi and Bluetooth 5.3 BLE.
To use the wireless functions use antenna cables to connect WiFi antennas (supplied with the eval-kit) to U6 antenna connectors A1 and A2.

CAN bus

CAN bus interface is available via header P17.
CAN bus on-board termination can be enabled by shorting jumper E6.

UART

Two UART interfaces are available on headers P19 and P20.

I2C

I2C interface is available via header P3.
Please refer to MCM-iMX93 reference guide and SB-MCMIMX93 schematics for details.

SPI

SPI interface is available via header P15.
Please refer to MCM-iMX93 reference guide and SB-MCMIMX93 schematics for details.

GPIO

GPIO signals are available via header P18.
Please refer to MCM-iMX93 reference guide and SB-MCMIMX93 schematics for details.

ADC

ADC signals are available via header P9.
Please refer to MCM-iMX93 reference guide and SB-MCMIMX93 schematics for details.

Reset

Pressing the reset button SW3 triggers system hardware reset.

Boot Sequence Selection

Pressing and holding the ALT BOOT button SW2 during power-up or hardware reset forces MCM-iMX93 to boot firmware from an SD card in socket P4.

RTC

RTC is implemented on MCM-iMX93 and receives power from coin-cell battery BH1.
Jumper E5 must be shorted for correct RTC operation.

JTAG

JTAG interface is available via header P11.
Please refer to MCM-iMX93 reference guide and SB-MCMIMX93 schematics for details.

LEDs

  • DS1 - Indicates connection of USB host to console port.
  • DS2 - Indicates presence of 12V power on the DC input jack.
  • DS3 - Indicates V_SOM power rail is enabled.
  • DS4, DS5 - user LEDs. Controlled by MCM-iMX93 GPIOs.

Jumpers Summary

  • E1 - USB2 multiplexing between mini-PCIe socket P8 and USB connector J2.
  • E2 - V_SOM power rail current measurement.
  • E3 - force MCM-iMX93 to perform firmware boot from SD card.
  • E4 - force MCM-iMX93 to enter serial download mode (SDP).
  • E5 - RTC battery power.
  • E6 - CAN bus termination control.

Default state:

  • Jumper E5 is populated
