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
