Austriamicrosystems launches latest RFID Reader IC
An Austriamicrosystems product story
Edited by the Electronicstalk editorial team Sep 10, 2009
Austriamicrosystems, a designer and manufacturer of high-performance analogue ICs for communications, industrial, medical and automotive applications, has launched the AS3910 HF RFID Reader IC.
Featuring good power efficiency and antenna auto-tuning, the AS3910 is well positioned for portable applications and products using printed circuit board antennas.
The AS3910 HF RFID Reader IC delivers 1W of output power from a 3.3V supply.
Combined with patent-pending antenna auto-tuning, the AS3910 is suitable for challenging environments.
Auto-tuning on chip means that there is no longer the need for the manual tuning of the antenna in production or in the field.
With the possibility to dynamically auto-tune 10 per cent of the resonant frequency, the user can spend less time on system issues where there is a lot of metal in the field.
This allows the customer to get to market quicker and focus more effort on building his or her unique IP around the AS3910.
Including ISO 14443 A and B data framing on chip and incorporated automatic modulation depth adjustment allows even a relative novice to become an implementer of radio-frequency identification (RFID), according to the company.
The power efficiency and true differential drive mean that the AS3910 is suitable for ISO 15693 applications.
The AS3910 enables read ranges of up to 30cm with no need for any external booster circuitry.
