125KHz LF programmable 3D wakeup receiver with low power consumption

Austria Microsystems launched AS3932, a 3-channel low power low frequency wakeup receiver that offers high sensitivity at low current consumption for industry's best range. The AS3932 supports the widely used 125 kHz band and, through the optimization of power consumption, sensitivity and programmability, enables a variety of applications.

The AS3932 wakeup receiver has three independent receiving channels enabling detection of a wakeup signal from any direction. 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.

Based on its concept of flexible data stream management, the AS3932 offers a solution for RF designers, which require secure component sourcing without uncertainty about a supplier's long-term product availability.

Package: available in a TSSOP16 or a QFN (4x4) 16LD package
