EM4125 - Read Only Contactless Identification

Download the EM4125 datasheet PDF. This datasheet also covers the EM4025_EMMicroelectronic variant, as both devices belong to the same read only contactless identification family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • Anticollision protocol to identify a number of transponders (better then 20 tags/s at RF/32, 10 tags/s at RF/64) 55 bit memory array, laser programmable ROM Two mask programmable data rate options: RF/64 and RF/32 Data transmission reader to transponder: ASK 100% (OOK) Data transmission transponder to reader: ASK, Manchester Code On chip resonance capacitor On chip supply buffer capacitor & voltag.
