We consider a brane universe in a Reissner-Nordstrom-de Sitter background spacetime of arbitrary dimensionality. It is shown that the brane evolution is described by generalized Friedmann equations for radiative matter along with a stiff-matter contribution. On the basis of the (conjectured) dS/CFT correspondence, we identify various thermodynamic properties of the brane. It is then demonstrated that, when the brane crosses the de Sitter cosmological horizon, the CFT thermodynamics and Friedmann-like equations coincide. Moreover, the CFT entropy is shown to be expressible in a generalized Cardy-Verlinde form. Finally, we consider the holographic entropy bounds in this scenario.
