The EM4237SLIC/SLIX is a Long-Range Passive CMOS RFID Tag IC intended for use in applications that require contactless read/write memory with a certain level of security based on 32-bit password authentication. It offers a high level of flexibility in terms of memory management and access conditions. A memory block can be read/write protected and/or locked separately. The SLIC 1k-bit / SLIX 2k-bit R/W NV memory is organized in 32/64 blocks of 4-bytes. This latest generation of NV memory offers data retention of 60-years enabling solutions for long-term asset management applications.

This RFID tag IC has 1024-bit / 2048-bit of user's free data memory and operates over a temperature range of -40 to 85°C. Chip application privacy and NV memory access conditions are optionally protected by a 32-bit password, the good trade-off for the most part of anti-theft applications. To ensure a good level of privacy, the chip can be personalized to remain silent to any command received from the RFID interrogator or be programmed to return a random ID number value.

The EM4237SLIC/SLIX features are enriched with a Smart Electronic Article Surveillance (EAS) mainly used in library applications. The EAS is configurable and programmable providing the maximum efficiency and optionally protected by the IC password. The IC supports all the ISO/IEC 15963-3 mandatory commands and many of the optional commands. The chip command set is completed by custom commands providing a higher degree of differentiation in terms of security, flexibility, and data protection. This device is available in an ultra-thin DFN403 package and is ideal for library management, access control, industrial laundries, ticketing, casino and gaming, and supply chain management applications.
