RFID-Slide15

Based on the ATA5567 core, the ATA5570 is a quite unique RFID chip. It has a 1-bit input to detect status signals in closed-loop applications. This helps to avoid wiring in critical environments or moving objects, for example. The status information is transferred by transmitting a code that has been programmed into the user memory. Depending on the sensor input signal, the code is transmitted as is, or completely inverted. The link reliability is significantly increased since it is not possible to fake the code or disturb the communication by interferences. The device is typically shipped in wafer form, but is also available in SO8 packages. SO8-packaged, a capacitor is also on chip so only the antenna has to be added externally.
