EM4069 - 128-bit Read/Write Contactless Identification

General Description

EM4069 (previously named P4069) is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders, with an optional lock function to disable EEPROM write operations.

Key Features

  • 128 bit EEPROM organized in 8 words of 16 bits 64 bit fixed code memory array laser programmed OTP feature convert EEPROM words in read only Power on Reset sequence Power-check for EEPROM write operation Data transmission performed by Amplitude Modulation (IC to reader and reader to IC) Data encoding : Manchester or BI-Phase (FDX-B) Transmission reader to chip: typically 65% AM modulation Data rate : 64 or 32 RF field periods per bit (2 kBaud or 4 kBaud at 125 kHz) 78 pF resonant capacitor integ.

EM MICROELECTRONIC - MARIN SA EM4069 EM4169 128 bit Read/Write Contactless Identification Device with OTP function Description EM4069 (previously named P4069) is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders, with an optional lock function to disable EEPROM write operations. 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’s from its internal EEPROM or ROM 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 AM modulation of the 125 kHz magnetic field.
