Technical Specifications for Verdin iMX8M Plus Quad 4GB IT

Based on the documentation, I can provide the following technical details:

1. Brownout Voltage

The recommended operation conditions show the main power supply (VCC) requirements(1):

  • Minimum: 3.135V(1)
  • Typical: 3.3V or 5V(1)
  • Maximum: 5.5V(1)

2. Thermal Resistance from Junction to Top of iMX8MP Chip Case

From the V1.1 datasheet (the newer version), the thermal specification shows(2):

  • Thermal Resistance Junction-to-Top of i.MX 8MP chip case (ReJCtop): 0.98 °C/W(2)

3. Current Driving Strength of IO Pins

The documentation doesn’t provide specific current driving strength values for the IO pins in the available sources. For detailed electrical characteristics including drive strength specifications, you would need to refer to the complete electrical specifications section of the datasheet.

4. Current Consumption

The power consumption information is referenced but specific values are not detailed in the provided sections(1). The documentation states that for designing and scaling power supplies, it’s advised to follow the recommendations in the Verdin product family specification(1). For module-specific power consumption information, the documentation refers to consulting the Developer Website(1).

Additional Thermal Information

The module incorporates DVFS (Dynamic Voltage and Frequency Scaling) and Thermal Throttling, with these operating parameters(2):

  • Operating temperature range: -40°C to 85°C(2)
  • Junction temperature SoC: -40°C to 105°C(2)
  • Thermal Resistance Junction-to-Ambient (RθJA): 21.1 °C/W(2)

Note: The Wi-Fi module is currently only validated from -30°C to 85°C, with validation down to -40°C pending(2).

For complete electrical specifications including detailed current consumption and drive strength values, I recommend consulting the full datasheet or contacting Toradex technical support for comprehensive electrical characteristics.
