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 integrated on chip
■ 100 to 150 kHz frequency range
■ On-chip rectifier and voltage limiter
■ No external supply buffer capacitor needed
■ -40 to +85°C temperature range
■ Very low Power consumption
