MW 08:07 PM PCB Development: RE: Unconnected pins, board dimensions and hole positions

Hello.
1. Generally speaking, all of the MFIO pins are direct connects to the AM57xx CPU device and if they are unused in your design it is safe to leave them not connected. The Ball numbers are included in the table and can be cross... Michael Williamson

TC 06:51 PM PCB Development: Unconnected pins, board dimensions and hole positions

Posting on behalf of customer:
1.The J1 and J3 connectors of MitySOM-AM57 are described as “MFIO” for “Type”.
"If this pin is not used, can it be left unconnected?"
(Table 6, Table 7 in MitySOM-AM57_datasheet.pdf)
2.Is it okay... Thomas Catalino

SS 04:53 PM PCB Development: RE: Design support for DP83640 Phy IC for use with AM57x SOM

Hi,
For testing IEEE 1588 H/W time stamp application, we included DP83640 in our circuit. Since DP83640 doesn't have 1.8V I/O level, we used Voltage level converters TXS0104E (Bidirectional, Push-pull and Open drain compatible) and SN... Sandeep Sivadas

JC 01:47 PM PCB Development: RE: eMMC support for MitySOM AM572x

Per this e2e post, it should be okay to use 1.8V signal levels with an eMMC.

The eMMC_RSTn signal can be connected to any gpio on ... Jonathan Cormier

SS 07:25 AM PCB Development: RE: eMMC support for MitySOM AM572x

Hi Jonathan,
We designed an eMMC circuit using *MTFC16GAPALBH-AIT*. As per the data sheet of MitySOM MMC2 signals are 1.8V level.
we follow the AM572x-IDK schematic design for designing eMMC circuit. But there an eMMC_RSTn signal is ... Sandeep Sivadas

The USB2_DM/DP supports 5V voltage level. Datasheet will be updated on next release. Jonathan Cormier

JC 02:11 PM PCB Development: RE: Design support for USB for use with AM57x SOM

Thanks, I'll look into it. I'm pretty sure that's incorrect. Jonathan Cormier

SS 05:49 AM PCB Development: RE: Design support for USB for use with AM57x SOM

Hi Jonathan,
*1. For USB2, it is mentioned that voltage level is 1.8V. We need to connect these signals to USB3.0 StdA Connector
Can you point me to the documentation your referencing?*
