CY51x7/CY294xx Datasheet can't find thermal resistance information.

Did you have θja, θjb, θjc etc. for reference?

Hi Mitchell,

We have the Theta Ja parameter for CY294XX devices. The Theta Ja for Quad Flat No Lead (QFN), 3x3x0.6mm is 27.04 C /W and for Leadless Chip Carrier (LCC), (5x7mm and 5x3.2mm) is 20.70 C/W. 

Thanks,

Pradipta.
