Supply Current for JTAG-SMT3-NC

[Patrick J. Mills]

To Whom It May Concern,

I'm interested in the JTAG-SMT3-NC and would like to know the Max & Min current draw for the "Vdd" module voltage.

Thank You,

Hi @Patrick J. Mills,

I asked the design engineer about this and received the following information.

- When the USB controller is held in reset the current consumption is ~20 mA
- When the USB controller comes out of reset and enumerates on the USB bus it's ~87.5 mA
- When both channels are being used, the worst case current draw on Vdd is around 115 mA with 90 mA typical.

You didn't ask this, but they also let me know that for Vref the current draw at 30 MHz is 12.5 mA typical and 35 mA max.

Let me know if you have any questions.

Thanks,
JColvin
