Note 4 on page 136 of the data sheet says the package is designed to be soldered to a thermal pad on the board. Which thermal pad do you recommend?

Hi Justin,

The thermal pad of the package should be connected to a PCB pad connected to GND. The recommended land pattern is shown in the diagram. You can also generate the CAD symbols for various CAD software from the tool below. I don't see the -SP version in the tool, but you can find the MSP430FR5969 which is the same package.

Hi Eddie, thanks helpful. Do I understand correctly, no secondary thermal pad is recommended?

Right, you just connect the thermal pad of the package to the ground plane of the PCB through vias.
