4205-4305-DS-01 512 bit Read/Write Multi-purpose Contactless Identification Device Description EM4205/4305 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders. It is suitable for low cost solutions like animal tagging applications. The IC communication protocol is compatible with the EM4469/4569 family. The main difference between the EM4205 and EM4305 is that:  EM4305 are bumped with enlarged pads for the two coil inputs. The enlarged bumped pads of the EM4305 transponder are intended for direct antenna connection avoiding the need of a module.
