NUCLEO-H753ZI ADC channel Pins location - Can those pins be accessible on this board

[RongShengWang]

Hi,

  Refer to NUCLEO-H753ZI's schematics - mb1364-h753zi-c01_schematic.pdf 

1.  About 8 ADC channels go to CN11 and CN12 on this schematics without the pin numbers denoted..

    Do all pins on the connectors CN11 and CN12 accessible since there are no physical connectors?  

2. PA0_C, PA1_C, PC2_C, PC3_C, PH2, PH3, PH4, PH5  are all ADC channels, but they are missing in the schematics. Why?

Below is what I found -

Hello,

1- Not sure I understood your question. CN11 and CN12 pins are accessible.

See the user manual of the board UM2407 / Table 22:

2- Not all pins with _C are available on the LQFP144 package, please read this article. 

And also PC2 & PC3 are not available on this package, only PC2_C and PC3_C are available and I think PC2, PC3 on the board refer to PC2_C and PC3_C.

For PH2, PH3, PH4, PH5, these pins are not available on the LQFP144 package, please refer to the datasheet.

Hope I answered your questions.

Hi,

so you ask ..where are PH2...5 , etc. ?

Well, first look at ds and on chip version: we are on 144 pin lqfp here, so it cannot have all pins, a 208 pin case has,

just see ds , which pins in which case are bounded :

PH2...5 , etc. - are not here, in 144 pins !

ok ?

Thanks,

In the schematics -  CN9-9 (SB53) - what "SB" means? Also CN10-7 DNF   what "DNF" means?

Thanks again,

Rong

SB = Solder Bridge (like 0 ohm resistor)

DNF = Do Not Fit (not available by default)

Thanks!
