General Description

AS3931 is an ultra low power, three channel LF ASK receiver designed to operate in various applications such as LF identification systems and LF tag receivers.

AS3931 is able to detect a low frequency ASKmodulated signal by looking for a digital wake-up pattern and generates a WAKE signal after successful pattern detection.

The device incorporates an intelligent pattern detection algorithm that provides reliable operation even in presence of strong interferences.

Key Features

  • Antenna rotation switch three independent LF receiver chains Wake-up output combining the three receiver chains Low power 32.768 kHz crystal oscillator circuit Serial programming interface Voltage regulator with 2.4 V output, on/off switchable 2. Key Features - 3D wake-up pattern detection 3D LF field strength measurement Antenna rotation for easy calibration High sensitivity and high dynamic range Wide operating frequency range Reliable, interference resistant wake-up decoding Highly protecte.
