Low-frequency receiver packs RC oscillator

austriamicrosystems has beefed up its RF product portfolio with the AS3930, a single-channel low-power, low-frequency wakeup receiver which claims to offer the highest sensitivity at lowest current consumption.

The AS3930 supports the125kHz band and, through the optimization of power consumption, sensitivity and programmability, enables a variety of applications.

The device has a single receiving channel and an internal RC oscillator, allowing a 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" said Mark Richey, transceiver senior marketing manager at austriamicrosystems.

Based on a 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 (4mm x 4mm) 16LD package and is suitable for operating environments ranging from -40°C to +85°C.
