EM4469 Datasheet 512 Bit Read/write Contactless Identification Device

Manufacturer: EM Microelectronic (Swatch Group)

Overview: EM MICROELECTRONIC - MARIN SA EM4469 512 bit Read/Write Contactless Identification.

General Description

EM4469 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders.

The IC is powered by picking the energy from a continuous 125 kHz magnetic field via an external coil, which together with the integrated capacitor form a resonant circuit.

The IC read out data from its internal EEPROM and sends it out by switching on and off a resistive load in parallel to the coil.

Key Features

  • 512 bit EEPROM organised in 16 words of 32 bits.
