Austriamicrosystems has developed two new RFID reader chips combining low power operation, small size, and low cost to enable RFID implementation in embedded portable and consumer devices.
The AS3993 and AS3980 both operate at very low power (75 mA on a supply voltage of 3.3 V), which means these RFID reader ICs are well suited for use in portable and battery-powered equipment such as mobile phones.
