AS3932

The AS3932 is an ultra low power 3-axis ASK wakeup and data receiver that is able to generate a wakeup upon detection of an OOK modulated data signal which uses a low frequency carrier. The integrated correlator is available for analysis of the programmable wakeup pattern. The device can operate using one, two or three active channels.

AS3932 provides a digital RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. AS3932 offers a fully integrated real-time clock (RTC), which is either derived from a crystal oscillator or the internal RC oscillator.

The programmable features of AS3932 enable to optimize its settings for achieving a longer distance while retaining a reliable wakeup generation. The sensitivity level of AS3932 can be adjusted in presence of a strong field or in a noisy environment.
