Hi Shoo,
Pin 19-22 are VSS pins for GND, there is a typo in pin description.

Hi Daveon,
The following pin name is different in the datasheet. they are all same pin? When is the RTM of this device? Those typo would be fixed in the RTM version?
・VSSD in Page 1, simplified block diagram
・VSSA in Page 3 , pin assignment
・AVSS in Page 11, absolute max ratings

Hi Daveon,
Is VSS digital ground? and is VSSD, VSSA,AVSS is analog ground?

Hi Saga-san,
It may be more helpful to take a look at the EVM schematic symbol. The data sheet has typos that make it hard to keep track of the different ground connections:
VSS can be treated as an analog ground. VSSD is a digital ground.

Hi Jeff-san,
Customer is designing the borad right now. especially they want to know the correct pin layout. Could you check the below table is correct?
Official name(EVM Schematic) | VSSD | VSS |
simplified block diagram in page 1 | VSSD | VSS |
pin assignment in Page 3 , | VSS | AVSS |
absolute max ratings | VSS | AVSS |

Hi Saga-san,
If I understand your table correctly, it would be as follows:
Official name(EVM Schematic) | VSSD | VSS |
simplified block diagram in page 1 | VSSD | VSS |
pin assignment in Page 3 , | AVSS | VSS |
absolute max ratings | AVSS | VSS |
VSS is the thermal pad and corner pad ground connections. This should be tied to analog ground.
VSSD can be tied to digital ground.
