Datasheet
1 General Description
The AS3931 is an ultra low power, three channel LF ASK receiver
designed to operate in various applications such as LF identifications
systems and LF tag receivers. AS3931 detects a low frequency
ASK-modulated signal by looking for a digital wakeup pattern and
generates a WAKE signal after successful pattern detection. The
device incorporates an intelligent pattern detection algorithmthat
provides reliable operation in presence of strong interference. An
RSSI signal can be generated at the RSSI pin for each receiver
channel.
The product is available in 16-pin TSSOP package.
The AS3931 contains:
Antenna rotation switch
Three independent LF receiver chains
Wakeup output combining the three receiver chains
Low power 32.768kHz crystal oscillator circuit
Serial programmng interface
Voltage regulator with 2.4V output, on/off switchable
Each independent LF receiver chain contains:
Input overload protection
Input attenuator
Ultra low power LF amplifier with logarithmc envelope output
Robust data detector with adaptive slicing threshold that
translates the logarithmc envelope into a digital data signal.
Error tolerant digital pattern correlator that detects a given code
sequences in the received data signal and generates a wakeup
signal.
Sophisticated power management logic that powers down the
correlator if no data is received.
2 Key Features
Programmable Serial Data Interface
Flexible carrier frequencies
