Track a specific cow or sheep in herd through NXP's new RF ID Ics

NXP announced its latest low frequency RFID IC, HITAG µ aimed at livestock identification and industrial logistics. The new chip offers high RF performance for tracking of livestock with industry benchmark read distances. Due to a fast write command feature the product has been optimized for initial set-up, reducing the programming time.

This is the first RFID chip for passive low frequency tags on the animal identification market to feature anti-collision technology. The algorithm ensures that multiple tags can be read at any given time allowing for individual animals in a herd to be identified. In other multiple tag applications, such as production control or asset management, the increased read distance, optimized anti-collision algorithm and reduced write times allow for a best in class identification solution, provided at competitive cost levels.

Some of the other features are listed below:

1. Optional security with 32-bit read and/or write password
2. Enables global use through worldwide-harmonized RF regulations - ISM band
3. Unique NXP programmed 48-bit identifier
4. Multiple User memory types
5. 3% tolerance of resonance capacitance allowing mass production without tuning of antennas
6. Multiple delivery forms including mega-bumped ICs and metal-straps
7. Supports the existing ISO11784/85 and is fully compliant with the existing low frequency infrastructure in the market.
