Pin-to-pin and firmware patible with the superset device TRF7970A. Built-in programming options make the device suitable for a wide range of applications for proximity and vicinity identification systems. The device is configured by selecting the desired protocol in the control registers. Direct access to all control registers allows fine tuning of various reader parameters as needed. The TRF7964A device supports data rates up to 848 kbps with all framing and synchronization tasks for the ISO protocols onboard. Other standards and even custom protocols can be implemented by...
