AS3930 - Single Channel Low Frequency Wakeup Receiver

Description

The AS3930 is a single-channel low power ASK receiver that is able to generate a wakeup upon detection of a data signal which uses a LF carrier frequency between 110 - 150 kHz.

The integrated correlator can be used for detection of a programmable 16-bit wakeup pattern.

Features

  • of AS3930 enable to optimize its settings for achieving a longer distance while retaining a reliable wakeup generation. The sensitivity level of AS3930 can be adjusted in presence of a strong field or in noisy environments. The device is available in 16 pin TSSOP and QFN 4x4 16 LD packages. Highly resistant to false wakeups False wakeup counter Periodical forced wakeup supported (1s.
  • 2h) Low power listening modes Current consumption in listening mode 1.37 µA (typ. ) Data rate adjustable.

Data Sheet AS3930 S i n g l e C h a n n e l L o w F r e q u e n c y Wa k e u p R e c e i v e r 1 General Description The AS3930 is a single-channel low power ASK receiver that is able to generate a wakeup upon detection of a data signal which uses a LF carrier frequency between 110 - 150 kHz. The integrated correlator can be used for detection of a programmable 16-bit wakeup pattern. The AS3930 provides a digital RSSI value, it supports a programmable data rate and Manchester decoding with clock recovery. The AS3930 offers a real-time clock (RTC), which is either derived from a crystal oscillator or the internal RC oscillator. The programmable features of AS3930 enable to optimize its settings for achieving a longer distance while retaining a reliable wakeup generation.
