AS3930 Datasheet | ams

Single Channel Low Frequency Wakeup Receiver General Description The AS3930 is a single-channel low power ASK receiver that is able to generate a wake-up upon detection of a data signal which uses a LF carrier frequency between 110 - 150 k Hz. The integrated correlator can be used for detection of a programmable 16-bit wake-up pattern. The AS3930 provides a digital RSSI value, it supports a programmable data rate. 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 wake-up generation. The sensitivity level of AS3930 can be adjusted in presence of a strong field or in noisy environments. The device is available in a 16-pin TSSOP and a 16-LD QFN (4x4) package. Ordering Information and Content Guide appear at end of datasheet.
