Description: EM card has 32 bit password read / write protection, 32 bit unique ID code and 10 bit user code. The EM card has 512 bits of EEPROM storage space and is divided into 16 sectors, each of which is 32 bits, where the lock position can turn the EEPROM data block into read-only mode. EM4469 can provide a wide range of data transmission rates and coding modes at lower power consumption, and its integrated resonant capacitor can mask selection without the need for external capacitance. In addition, it has an on-chip rectifier and a voltage limiter that can operate at -40 degrees ~85 degrees Celsius
