T1042 No connect


T1042 No connect

Contributor II

This is with reference to the T1042datasheet

They are calling out Seven No Connection pins that are connected to VDD in a reference design.

Could you tell me if these pins are NC or VDD connections? We are just about to finish our layout and need this information.

I have attached the document.

 Pins that are connected to VCC are M9, P9, T9, V9, Y8, Y9 and Y11.

This is done for compatibility with T2081 processor.

If you are designing a board compatible with T2081, than you can connect these pins as required for T2081 processor - to VDDnn.

If you are not considering migration to T2081, and designing a board for only T1040 processor, than you can leave these pins as no connect.

We have a preliminary application note AN4773 describing migration between T2081 and T1040 families, this information is specified in Table 16 of this document. Sorry, I can not attach this document in in this public community, please enter a case to request this document.

How I could create a Service Request? 

Have a great day,
