Overview
The CP85728 is a RFID IC made by CenChip in a QFN-24-EP(3x5) package with 25 pins. QFN-24-EP(3x5) RFID ICs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CP85728, from EasyEDA) and its footprint (EasyEDA_Cloud:QFN-24_L5.0-W3.0-P0.50-TL-EP, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2874133).
