Details
General Description The AS3932 is a 3-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 device can operate using one, two, or three active channels. The AS3932 provides a digital RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. The AS3932 offers a real-time clock (RTC), which is either derived from a crystal oscillator or the internal RC oscillator. Key Features 3-channel ASK wakeup receiver Carrier frequency range 110 - 150 kHz One, two, or three channel operation Reliable 1-, 2- or 3-D wakeup pattern detection Programmable wakeup pattern (16bits) Doubling of wakeup pattern supported Wakeup without pattern detection supported Wakeup sensitivity 100 µVRMS (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 3-channel listening mode 1.7 µA (typ.) Data rate adjustable from 0.5- 4 kbps (Manchester) Manchester decoding with clock recovery Digital RSSI values available for each channel 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 16LDApplications The AS3932 is ideal for Active RFID tags, Real-time location systems, Operator identification, Access control, and Wireless sensors.
