EM4025 Read Only Contactless Identification Device with Anticollision

The EM4025 is a CMOS integrated circuit for use in electronic Read Only RF Transponders, often known as a RFID Tag. The circuit is powered by an external coil placed in an electromagnetic field, and gets its clock via the coil terminals. The fixed code device identification is programmed at manufacture by laser fusing of polysilicon links. The chip starts at.
