Mu3e is a novel experiment searching for charged lepton flavor violation in the rare decay mu->eee. Decay vertex position, decay time and particle momenta have to be precisely measured in order to reject both combinatorial and physics background. A silicon pixel tracker based on 50 um thin high voltage monolithic active pixel sensors (HV-MAPS) in a 1T magnetic field will deliver precise vertex and momentum information. The MuPix HV-MAPS chip combines pixel sensor cells with integrated analog electronics and a complete digital readout. The MuPix7 is the first HV-MAPS prototype having all functionality of the full sensor including a fast readout state machine and high speed serialization with 1.25 Gbit/s data output. Measurements for the MuPix7 pixel sensor chip including >98% efficiency for the full system in a high rate beam test will be shown.
