SLOA208B November 2014 – March 2019 TRF7970A , TRF7970A
To take advantage of the TRF7970 compatibility with both Type A and Type B reader/writers, only a single Type 4 tag is emulated within the example firmware. The tag is structured to support multiple applications, and multiple files within each application, which provides a flexible platform to emulate both tag types. Figure 8 shows a structural overview of the emulated tag that is in the firmware.
