1 / 32 page  AS3930 Single Channel Low Frequency Wakeup Receiver www.ams.com/LF-Receiver/AS3930 Revision 1.5 1 - 32 1 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 kHz. 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 package. 2 Key Features Single channel ASK wake-up receiver Carrier frequency range 110 - 150 kHz Programmable wake-up pattern (16bits) Doubling of wake-up pattern supported Wake-up without pattern detection supported Wake-up sensitivity 100µVRMS (typ.) Adjustable sensitivity level Highly resistant to false wake-ups False wake-up counter Periodical forced wake-up supported (1s – 2h) Low power listening modes Current consumption in listening mode 1.37µA (typ.) Programmable data-rate 0.5-4 kbaud (Manchester encoded) Digital RSSI Dynamic range 64dB 5-bit RSSI step (2dB per step) RTC based on 32kHz XTAL, RC-OSC, or external clock Operating temperature range -40ºC to +85ºC Operating supply voltage 2.4 - 3.6V (TA = 25ºC) Bi-directional serial digital interface (SDI) Package options: 16-pin TSSOP and QFN 4x4 16 LD 3 Applications The AS3930 is ideal for Active RFID tags, real-time location systems, operator identification, access control, and wireless sensors.
