AS3932
Austriamicrosystems has brought out the AS3932, a three-channel low-power low-frequency wakeup receiver that offers high sensitivity at low current consumption.
The AS3932 supports the 125kHz band and enables a variety of applications.
It 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.
The AS3932 is suitable for RF designers needing secure component sourcing without uncertainty about a supplier's long term product availability.
The AS3932 is available in a TSSOP16 or a QFN (4x4) 16LD package and is suitable for operating environments ranging from -40 to +85C.
