RFID INTERFACE AND INTERRUPT

摘要

A RFID system includes an RFID controller incorporating a serial bus master coupled via a serial bus to a serial bus slave device, whereby the RFID controller controls power supply and/or power mode of the salve device in order that the slave device is powered and able to communicate with the RFID controller in response to RFID commands received from an RFID reader, and unpowered or in a low power mode otherwise.
