The design of the Micro Vertex Detector for the PANDA experiment faces a number of challenging aspects. The high radiation level, the limited space and accessibility, the strict material budget combined with the absence of a trigger signal and thus the huge amount of data to be sent to the DAQ require innovative solutions. Hybrid silicon pixels based on epitaxial material are under study as a detector technology capable to sustain the expected radiation levels at room temperature. A reduced scale prototype for the readout ASIC in a CMOS technology has been designed and tested. Irradiation tests have been performed on both the detector and the readout ASIC.
