EM4133- NFC & High Frequency ICs

Read/Write, ISO/IEC 15693 Standard Compliant Device - Ultra-Low Power

General Description

The EM4133 is a CMOS integrated circuit intended for use in passive ontactless Read/Write transponders fully compliant with the ISO/IEC 15693 standard.

The user's configurable 448 bit EEPROM memory is organized in 14 words of 32 bits.

Each memory word can be write protect or irreversibly locked. The 32 bit password guaranties a good level of security for the protection of the data memory integrity. Each device contains a 64 bit unique serial number.

The ISO 15693 anticollision algorithm allows operating more tags in the field simultaneously. Moreover, the advanced Quiet Storage feature permits to have faster inventory processes in multi dimensional environments where the reader is multiplexing several antennas and the tags can be in any orientation inside the reader field.

The EM4133 is completely ISO/IEC 15693 compliant. It includes all ISO/IEC15693 mandatory and most part of the optional features, a set of attractive and useful custom commands.
