How Much Power Can the Promira Serial Platform Provide to a Target System?
Jessica Hopkins

The Promira Serial Platform is a versatile tool that can be configured for a variety of use cases and applications. It has a field upgradeable design that allows for multiple protocols and speed rates, and offers some of the most advanced features within our line of tools.

One of these features is its power providing capability, which allows users work with a wide range of power and voltage levels in one device. The Promira can provide up to 200 mA supplemental power – 100 mA at 5 V and 100 mA available from 0.9 V- 3.3 V. It also has integrated voltage level shifting where it does not require a separate Level Shifter Board.

How do the Aardvark and Cheetah Host Adapters Compare?

Other Total Phase host adapters, such as the Aardvark I2C/SPI Host Adapter and Cheetah SPI Host Adapter, do not offer the same high-power or built-in level shifting capabilities as the Promira Serial Platform. For instance, the Aardvark I2C/SPI Host Adapter can provide less than 100 mA to downstream devices; a maximum of 25 mA may be drawn from each pin:

NC/+5V (Pin 4): I2C Power

NC/+5V (Pin 6): SPI Power

With the Cheetah SPI Host Adapter, it is also possible to power a downstream target, such as an SPI EEPROM, but it also reports itself to the host as a low-power device (<100mA).

What the Promira Serial Platform Provides

The Promira platform is an advanced tool that surpasses these capabilities, allowing users to safely use the tool as a high-power source to power systems. For instance, it can provide low voltages compatible with a target system, but it can also can power up target systems using higher power levels when necessary.

How to Configure the Promira Serial Platform Power Features

Here is a quick step-by-step guide to configure the power features on your Promira Serial Platform:

  1. Connect the Promira Serial Platform to the respective target system and host PC.
  2. Open the Control Center Software and connect your Promira Serial Platform by clicking “Adapter” > “Connect”. Connect to device with matching serial number.
  3. Configure power preferences by clicking “Adapter” and choosing:

    1. Configure Target Power (pin 4, 6)
    2. Configure IO Power (pin 22, 24)
    3. Level Shift (0.9 V- 3.3V)
Configure Promira Target Power Promira-level-shift
