General description

The VisionSOM-iMX93 (SLS26) family is a SODIMM-sized SoM based on the NXP iMX93 application processor which features a heterogeneous dual cores ARM Cortex-A55 (up to 1.7GHz) together with an ARM Cortex-M33 MCU core (up to 250 MHz) as well as an advanced 2D graphics processing unit (PXP) and neural network/machine learning coprocessor (NPU).

The dual Cortex-A55 and single Cortex-M33 based VisionSOM provides full flexibility to support real time application while supporting Linux, advanced HMI and AI/ML.

The VisionSOM-iMX93 (SLS26) is a general-purpose highly integrated SoM (System on Module). The module is featuring high computation power inculding AI and ML coprocessor. The option is fully certified Wi-Fi (802.11b/g/n) and Bluetooth (BLE 5.1) module. This module simplifies the carrier board design and is ideally suited for wireless application. The VisionSOM-iMX93 provides a variety memory configuration, including flexible range of LPDDR4 and eMMC Flash.
The VisionSOM-iMX93 supports connections to a variety of interfaces:

  • two high-speed USB on-the-go with PHY,
  • 2 x 1Gbit/s Ethernet,

Notes:
1. Total current on both VDD-3V3 outputs.
2. Applying the maximum voltage 3.6V results in shorten lifetime. Recommended value is smaller than 3.45V.
3. Allowed maximum voltage range of USBx_VBUS input is 0...+3.95V but input current is limited by 30k resistor connected in series.

SoM pinout

Important notes:
1. Detail pin configurations description you can find, edit and arrange in dedicated MEX file (with free "iMX PinTool" configurational tool).
2. Following MPU lines are dual use:

RECOVERY = "0" then BOOT0 = "1", as a result serial loader starts
RECOVERY = "1" or open then BOOT0 = "0", as a result MCU boots from fuses.
7 - GND - - -
8 ONOFF PWR-ON - A19 1.8V power domain
A brief connection the PWR-ON to GND in the OFF mode causes the internal power management state machine to change the state to ON. In the ON mode, a brief connection the PWR-ON to GND generates an interrupt (intended to be a software-controllable power-down). Approximately five seconds (or more) to GND causes a forced OFF.
