Auto-tuning on chip means there is no longer the need for manual tuning of the antenna in production or in the field. With the possibility to dynamically auto tune 10% 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 their new IP around the AS3910.
Including ISO 14443 A & B data framing on chip and incorporated automatic modulation depth adjustment allows even a relative novice to become an implementer of RFID. The power efficiency and true differential drive means 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.
“The AS3910 changes the game in the HF RFID Reader arena,” said Bruce Ulrich director of marketing consumer business at austriamicrosystems. “The solution is perfect for experts and non consumers alike.”
RFID Reader product lines leverage over 15 years of RFID Reader experience. Testament to this, are market firsts such as the UHF 20dBm internal PA and HF antenna auto-tuning on chip.
The AS3910 is available now in QFN 32 5×5.
