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

JC 02:46 PM PCB Development: RE: Design support for USB for use with AM57x SOM: Datasheet has been released Jonathan Cormier

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.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/827480/am5718-emmc-at-1-8v
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

JC 07:06 PM PCB Development: RE: Design support for USB for use with AM57x SOM: 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?*

JC 09:31 PM PCB Development: RE: Design support for USB for use with AM57x SOM: Schematic review:
* Both schematics are using VUSB_VBUS1 as a net name. One of them is probably supposed to be VUSB_VBUS2.
* The SOM already contains 0.1uF caps on the USB1_SSTX_P/N lines, I don't believe they should be on the baseboa... Jonathan Cormier
SS 04:19 PM PCB Development: Design support for USB for use with AM57x SOM: Hi,
We need to integrate one USB 3.0, one USB 2.0 and one Debug USB with our application system.
1. For USB2, it is mentioned that voltage level is 1.8V. We need to connect these signals to USB3.0 StdA Connector
2. But for USB1... Sandeep Sivadas
