EM4237SLIC
Description
The EM4237/SLIX is a long range passive CMOS integrated circuit intended for use in applications requiring a contactless read/write memory and offering optionally a certain level of security based on a 32-bit password authentication.
The SLIC 1k-bit / SLIX 2k-bit R/W NV memory are organized in 32/64 blocks of 4-bytes. The EM4237SLIC/SLIX 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. This latest generation of NV memory offers data retention of 60-years enabling solutions for long-term asset management applications.
Chip application privacy and NV memory access conditions are optionally protected by a 32-bit password, good trade-off for most part of anti-theft applications. To ensure a good level of privacy, the chip can be personalized to remain silent to any mand received from the RFID interrogator or be programmed to return a random ID number value.
