Demo Kit for AS3955
The purpose of the demonstrator is to show all the features and functionalities of the AS3955. The demonstration works with an Android Smartphone or NFC Reader and an AS3955 tag. The main features of the demonstration are: - Demonstration of a Tag 2 Type (T2T) operation - Demonstration of a Tag 4 Type (T4T) operation - File transfer operation - Energy Harvesting The Evaluation kit allows you to supply all components by the PC USB port. No external supply or battery is needed. Except the USB cable (include) no wiring is needed. This allows a fast and comfortable evaluation of the AS3955. Compatibility This demo works with - AS3955 GP GUI version 4.0.8 or higher and FW 4.0.8 or higher - Android version 5.0 or higher
AS3953 ISO 14443A Sensor Interface Tag
AS3955 NFC Interface Tag
AS3956 NFC Sensor Interface Tag IC
Thanks to a high sensitivity ISO14443A frontend and high integrated resonance capacitor, AS3956 offers standalone NFC passive tag functionality in a small form factor. The AS3956 dynamic tag acts as a contactless bridge between sensors and any NFC reader, such as a smartphone, through a host microcontroller.
Fast system integration and high speed data transfer are guaranteed by the available SPI and I²C interfaces and by optimized protocols (Tunneling mode and Extended mode), allowing bidirectional communication between the device microcontroller and an external NFC compliant device or ISO14443A reader device. AS3956 is able to operate fully powered by the RF field, without any external supply. This, combined with an advanced energy harvesting feature, greatly increases battery life time or even allows battery-less designs.
