This paper describes a readout ASIC prototype designed by the CHIPIX65 project, part of RD53, for a pixel detector at HL-LHC. A 64 x 64 matrix of 50 x 50 mu m(2) pixels is realised. A digital architecture has been developed, with particle efficiency above 99.5% at 3 GHz/cm(2) pixel rate, trigger frequency of 1MHz and 12.5 mu sec latency. Two analog front end designs, one synchronous and one asynchronous, are implemented. Charge is measured with 5-bit precision, analog dead-time below 1%. The chip integrates for the first time many of the components developed by the collaboration in the past, including the Digital-to-Analog converters, Bandgap reference, Serializer, sLVS drivers, and analog Front Ends. Irradiation tests on these components proved their reliability up to 600 Mrad.
