Data Sheet AS3910 13.56 MHz RFID Reader IC, ISO-14443 A/B www.DataSheet4U.com 1 General Description The AS3910 is a high performance 13.56MHz HF RFID Reader IC. With austriamicrosystems’ unique antenna management technology it is optimized for applications with directly driven antennas. The AS3910 is unequalled in the domain of HF Reader ICs in that it contains two differential low impedance (1.5Ω) antenna drivers. These drivers are unmatched meaning the IC can deliver up to 8 times the output power of a standard HF Reader IC using the same power supply voltage. Additionally using this configuration means half of the power consumption at the same output power. The IC has an operating voltage down to 2.4V and a low power operating mode of 5mA.
