austriamicrosystems high performance single-channel LF wakeup receiver

AS3930 is a fully programmable low frequency wakeup receiver offering the longest range and battery life in active tags

austriamicrosystems a leading global designer and manufacturer of analog ICs
for communications, industrial, medical and automotive applications,
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 125 kHz band and, through
the optimization of power consumption, sensitivity and programmability,
enables a variety of applications.

austriamicrosystems’ 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

“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 (4×4) 16LD package and is suitable for
operating environments ranging from -40 to +85°C.
