austriamicrosystems AS3910 HF RFID Reader IC

The AS3910 is a high performance 13.56MHz HF RFID Reader IC. With unique antenna management technology it is optimized for applications with directly driven antennas. The AS3910 is unique in the domain of HF RFID 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 RFID Reader IC using the same power supply voltage. Additionally using this configuration means half of the power consumption at the same output power. austriamicrosystems AS3910 Datasheet (PDF) View ALL austriamicrosystems products Key Features Close loop adjustment of ASK modulation for accurate control of modulation depth in case of ISO-14443B protocol Antenna trimming system providing correction range of LC Low power operating mode reduces receiver consumption from 10mA to 5mA Low power (3.5μA) NFC target mode Integrated regulators to boost system PSRR AM/PM demodulator to eliminate communication holes RSSI measurement Accurate RF envelope measurement (8 bit A/D) About austriamicrosystems austriamicrosystems is a leading designer and manufacturer of high performance analog ICs, combining more than 27 years of analog design capabilities and system know-how with its own state-of-the-art manufacturing and test facilities.
