Other Parts Discussed in Thread: USB2ANY, DPS-DONGLE-EVM

Hello Team,

We would like to know the I2C/SPI line schematic of the DPS Dongle and USB2ANY. Could you please provide us the schematic of each Dongle ?

The background is that customer is considering to connect the dongle to their system board. We are asked if they need to care the pull up voltage.

Best Regards,

Kawai

I believe each data clock pins of SMBus is open drain with no pull up. How about SPI ?

Best Regards,
Kawai

Hi Kawai-san,

Please find a copy of the DPS-DONGLE-EVM schematic attached:

DPS-DONGLE-EVM_Schematics.PDF

A schematic of the USB2ANY is below:

The DPS-DONGLE-EVM SMBus data and clock pins are open drain, as our DPS device EVMs all provide pull-ups on the EVM board itself. The USB2ANY dongle has on-board optional pull-ups that can be enabled if desired.

The SPI pins for the DPS-DONGLE-EVM and USB2ANY do not have any pull-up or pull-down resistors connected.
