\textit{Topmetal-${II}^-$} is a highly pixelated direct charge sensor thatcontains a 72${\times}$72 pixel array of 83${\mu}$m pitch size. The key featureof \textit{Topmetal-${II}^-$} is that it can directly collect charges via metalnodes of each pixel to form two-dimensional images of charge clouddistributions. \textit{Topmetal-${II}^-$} was proved to measure chargedparticles without amplification at room temperature. To measure its performanceat cryogenic temperature, a \textit{Topmetal-${II}^-$} sensor is embedded intoa liquid nitrogen dewar. The results presented in this paper show that\textit{Topmetal-${II}^-$} can also operate well at this low temperature with anoise (ENC) of 12 e$^-$ lower than that at room temperature (13 e$^-$). Fromthe noise perspective, \textit{Topmetal-${II}^-$} is a promising candidate forthe next generation readout of liquid argon and xenon Time Projection Chamber(TPC) used in experiments searching for neutrinoless double beta decay and darkmatter.
