EM MICROELECTRONIC - MARIN SA www.DataSheet4U.com EM4269 512 bit Read/Write Contactless Identification Device Description EM4269 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders. It is compatible to EM4469/4569 family. It is intended for direct connection of coil to big bumps. Comparing to EM4469/4569 family the changes are the following: ‰ New configuration bit co25 which inverts data input to encoder is introduced. ‰ Writing to Protection Word is modified. 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.
