Hi.

For our footprint definition we require a confirmation from you:

  1.  The letter ‘C’ in the Pin Count ordering information is used for both 48 and 49 pins packages.
  1.  The WLCSP package is 49 pins.

Thanks in advance,

Noam

Hello ​@Noam_MSI ;


The C" refer to 48 pins /49 pins in Pin count and "Y "refer to WLCSP.
These typos will be corrected in the coming datasheet version.


Thank you.
