In this paper, we investigate the power functions F(x)=x^d over the finite field 𝔽_2^4n, where n is a positive integer and d=2^3n+2^2n+2^n-1. It is proved that F(x)=x^d is APcN at certain c's in 𝔽_2^4n, and it is the second class of APcN power functions over finite fields of even characteristic. Further, the c-differential spectrum of these power functions is also determined.
