1 / 33 page  AS3930 Single Channel Low Frequency Wakeup Receiver www.austriamicrosystems.com/AS3930 Revision 1.0 1 - 33 Data Sheet 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. 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. 2 Key Features Single channel ASK wakeup receiver Carrier frequency range 110 - 150 kHz Programmable wakeup pattern (16bits) Doubling of wakeup pattern supported Wakeup without pattern detection supported Wakeup sensitivity 100µVRMS (typ.) Adjustable sensitivity level 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 from 0.5 - 4 kbps (Manchester) Manchester decoding with clock recovery 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 -40 to +85ºC Operating supply voltage 2.4 - 3.6V (TA = 25ºC) Bidirectional serial digital interface (SDI) Package option 16 pin TSSOP, 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. |
