Abstract: We construct and study a $t$-structure on $p$-typical cyclotomic spectra and explain how to recover crystalline cohomology of smooth schemes over perfect fields using this $t$-structure. Our main tool is a new approach to $p$-typical cyclotomic spectra via objects we call $p$-typical topological Cartier modules. Using these, we prove that the heart of the cyclotomic $t$-structure is the full subcategory of derived $V$-complete objects in the abelian category of $p$-typical Cartier modules.
