EM4133
512 bit Read/Write, ISO15693 Standard Compliant Contactless RW Identification Device
General Description The EM4133 is a CMOS integrated circuit intended for use in passive contactless Read/Write transponders full compliant with the ISO 15693 standard.
The user’s configurable 448 bit EEPROM memory is organized in 14 words of 32 bits, each word can be irreversibly locked. The memory contains a 64 bit unique serial number.
The ISO 15693 anticollision algorithm allows operating more tags in the field simultaneously. IC is completely ISO 15693 compliant since it includes all ISO15693 mandatory features.
Applications Laundry Access Control Ticketing Asset management
Features ISO15693 Standard: Fully compliant, support all

Stresses above these listed maximum ratings may cause permanent damages to the device. Exposure beyond specified operating conditions may affect device reliability or cause malfunction.
Handling Procedures This device has built-in protection against high static voltages or electric fields; however, anti-static precautions must be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the voltage range. Unused inputs must always be tied to a defined logic voltage level.
