AS3930 LF RECEIVER IC

Programmable 1D LF Wake-up Receiver

The AS3930 is a single-channel ASK receiver that generates a wake-up signal upon detection of a data signal with a carrier frequency in the range of 110 – 150 kHz. It can be used to wake-up active tags in RTLS, PKE and other similar tracking and access control systems.

AS3930 Demo Kit

The AS3930 Demo Board displays the AS3930’s primary features. These include one-dimensional wake-up pattern identification, false wake-up readout, the ability to measure current consumption in various operating modes, and measurement access to SPI communication and data output. Using the 125 kHz wake-up transmitter board, you can immediately see how different settings affect detection efficiency.
