In this work, we study the spectral property of generalized Sierpinski-type self-affine measures μM,D on R2 generated by an expanding integer matrix MM2(Z) with det(M)3Z and a non-collinear integer digit set D={(0,0)t,(α1,α2)t,(β1,β2)t} with α1β2α2β13Z. We give the sufficient and necessary conditions for μM,D to be a spectral measure, i.e., there exists a countable subset ΛR2 such that E(Λ)={e2πiλ,x:λΛ} forms an orthonormal basis for L2(μM,D). This completely settles the spectrality of the self-affine measure μM,D.
