austriamicrosystems Announces a High Performance Single-channel 125kHz LF Wakeup Receiver Requiring Minimal External Components

(Product News, 1 Dec 2009)

austriamicrosystems expanded its RF product portfolio with the AS3930, a single-channel low power, low frequency wakeup receiver which offers the highest sensitivity at lowest current consumption for the industry’s best range. The AS3930 supports the widely used 125kHz band and, through the optimization of power consumption, sensitivity and programmability, enables a variety of applications.

The low frequency wakeup receiver AS3930 has a single receiving channel and an internal RC oscillator, allowing a very low external component count for maximum performance versus cost and reduced size. The received data can be correlated with a pattern that is programmed in the register preventing false wakeups.

Primary target applications are active RFID, high-value asset tracking, real-time location systems, operator identification and access control or keyless entry.

“By using the AS3930 wakeup receiver customers can achieve superior range and long battery life while minimizing size and system cost” says Mark Richey, Transceiver Senior Marketing Manager at austriamicrosystems. “The AS3930 is the latest addition to austriamicrosystems growing low frequency wakeup receiver product family, continuing the tradition of combining exceptional performance with simplicity”.

Based on its concept of flexible data stream management, the AS3930 offers an attractive easy-to-use solution for RF designers which require secure component sourcing without uncertainty about a supplier’s long term product availability.

The AS3930 single-channel low power low frequency wakeup receiver is available in a TSSOP16 or a QFN (4x4) 16LD package and is suitable for operating environments ranging from -40 to +85°C.
