austriamicrosystems, in partnership with IE Technology Ltd (IET), have released the IET RU-210u, mid-range (up to 2.5m), fixed UHF RFID reader with USB and serial interface.

The companies leveraged austriamicrosystems' AS3990/91 "Simply Gen 2," a single chip, EPC Class 1 Gen 2 UHF reader IC, which includes an EPC Class 1 Gen 2 protocol engine and is available with an integrated power amplifier to further reduce BOM. The Gen 2 UHF reader IC provides the high level of integration, low power consumption and low BOM cost.

The AS3990/91 also enables a fast time to market for customers, like IE Technology, by allowing them to focus more time on their unique IP and less time on a Gen 2 implementation. The AS3990/91's programmable features enable a single stock-keeping unit that is world-wide shippable. Its simplicity is emphasised with only 32 registers to enable full RF, filtering, and protocol control, while maintaining flexibility and versatility.

The RU-210u UHF RFID reader, with USB interface, is well-suited for logistics, manufacturing and retail applications. It is already proven in closed loop pallet and crate tracking systems in several Asian markets.

The AS3990/91 is available in QFN 64 9x9 mm package and is specified for 0 to 70° C. Further information is available at
