| EM MICROELECTRONIC - MARIN SA 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. 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. Commands and EEPROM data updates can be executed by 100% AM modulation of the 125 kHz magnetic field. There are several data rate and data encoding options available. Options are stored in EEPROM Configuration word. Read and write access to EEPROM can be protected by 32 bit password. All EEPROM words can be write protected by setting lock bits which transform them in read-only. It contains factory programmed and locked 32 bit UID number, chip type and customer code. The resonant capacitor value is selected by metal mask. Features 512 bit EEPROM organised in 16 words of 32 bits 32 bit Password read and write protection 32 bit unique identification number (UID) 10 bit Customer code ISO 11784 / 11785 Standard Compliant Lock feature convert EEPROM words in read only Multi-purpose encoding (Manchester, Biphase, Miller, PSK, FSK) Multi-purpose data rate from 1 up to 32k baud 100 to 150kHz frequency range On-chip rectifier and voltage limiter No external supply buffer capacitor needed -40 to +85C temperature range Very low Power consumption Big pads (200 m x 400 m) for direct connection of coil using bumps Resonant capacitor with options 330pF, 250pF and 75pF integrated on chip Applications Access Control Animal Identification according to ISO FDX-B Material Logistics Typical Operating Configuration C1 L C2 EM4269 Fig 1 EM Microelectronic-Marin SA (EM) makes no warranty for the use of its products, other than those expressly contained in the Company's standard warranty which is detailed in EM's General Terms of Sale located on the Company's web site.
