Schematic of MityARM-3354

Added by Nikita Spirin over 3 years ago

Hi,
I need the schematic of MityARM-3354 SOM and Development Kit. How can I access to it?

Q2:
On TI Wiki i found recommendations to Unused Signals http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#Unused_Signals ,
There is a recomendations about unused ADC pins:
"Connect all TSC_ADC terminals (VREFP, VREFN, AIN[7:0], VDDA_ADC, and VSSA_ADC) to same ground as all VSS terminals."
But VDDA_ADC pin doesn't connected to any pin on SODIMM connector, am I right? So, what should i do in situation when ADC isn't used?

Hi Nikita,

The schematic for the Dev Kit is available on this support site, under the Files tab on the MitySOM-335x Dev Kit project. Look for the filenames containing "SCH."

We do not provide the schematic for the SOM on the support site.

VDDA_ADC is connect to the 1.8V rail of the PMIC and test point (TP4). I would expect that grounding AIN* and VREF* would still be sufficient though your welcome to ask TI and get back to us.

Unless this is a battery application, it shouldn't matter.
