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.
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.
