| EM MICROELECTRONIC - MARIN SA 512 bit Read/Write Contactless Identification Device Description EM4369 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders. It is functionaly equivalent to the EM4269 and compatible with the 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 (configuration word), which inverts data input to the encoder. 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 reads out data from its internal EEPROM memory 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. The IC Options are stored in EEPROM configuration word (word 4). 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 a factory programmed and locked 32 bit UID number, chip type and a customer code. The on-chip resonant capacitor value is selected by metal mask (three different options). EM4369 Features 512 bit EEPROM organized 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, bi-phase, Miller, PSK and FSK) Multi-purpose data rate from 1 up to 32k bauds 100 to 150 kHz 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 80pF, 250pF and 330pF integrated on chip Applications Access Control Animal Identification according to ISO FDX-B Material Logistics Typical Operating Configuration C1 L C2 EM4369 Fig. 1 Copyright (c) 2006, EM Microelectronic-Marin SA Subject to change without notice Rev.
