Atom E3900 LPC level shifter IC suggestion

Atom can set LPC level to 1.8V or 3.3V by strap and we will set to 1.8V in the design because we got some erratum from Intel to prevent degrade issue.

But the devices that connect to Atom are all 3.3V level in our design. We want to know if you have any suggestion for LPC level shifter IC(1.8V to 3.3V)?

Thank you for contacting Intel Embedded Community.

In order to help we suggest you address this request to the person that gave you the mentioned erratum information.

We hope that this information may help you.

Take a look at the TI TXB0104RUTR. They are nice little bi-directional level translators.

You can check TI LSF0101 and LSF0108, those series could be suitable for your application.
