Differences between TRF7960 and TRF7970A

Posted: 14 Nov 2011     Print Version  Bookmark and Share

Keywords:RFID  NFC  reader 

Here's a document intended to help users of the TRF7970A high-frequency RFID/NFC reader IC understand the differences between it and the TRF7960 IC. Understanding these differences in detail and applying this knowledge to application-specific requirements can assist in development efforts.

The TRF7960 has limitations with ISO14443A and ISO14443A-like protocols that require firmware workarounds. Resolving these limitations directly inside the TRF7960 is the primary reason for the introduction of the new device. New users or developers implementing the ISO14443A protocol might want to consider using the TRF7960A or TRF7970A first. Users who are already familiar with the workarounds and are in full production with the TRF7960 might consider migrating to the TRF7960A or TRF7970A only when it makes logical sense or to add full NFC capabilities.
