ams AS3993 UHF Reader Chip

The ams AS3993 UHF Reader Chip is the first in the next generation of EPC Class 1 Gen2 RFID Reader ICs. It has a completely new low power architecture, down to 2.7V with 65mA, enabling battery powered, small form factor handheld and embedded applications. The AS3993 now delivers high performance Gen 2 in a small QFN48 7x7, while retaining the flexibility, integration and simplicity of the previous generations. The small size combined with the low power operation makes it ideal for embedded or mobile applications.
