ScioSense | AS3933-BQFT

This device provides a digital RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. It offers an internal Clock Generator, which is either derived from a crystal oscillator or the internal RC oscillator. The user can decide to use the external clock generator instead.

Features:

• Carrier frequency range 15 - 150 kHz
• One, two, or three channel operation
• Reliable 1-, 2- or 3-D wakeup pattern detection
• Programmable wakeup pattern (16-bit or 32-bit) Manchester
• Doubling of wakeup pattern supported (both for 16 and 32 bits)
• Wakeup without pattern detection supported
• Wakeup sensitivity 80 μVRMS (typ)
• Adjustable sensitivity level
• Highly resistant to false wakeups
• Easy antenna tuning for perfect matching on the wanted carrier frequency
• Self calibration of the internal RC-oscillator
• False wakeup counter
• Periodical forced wakeup supported (1s – 2h)
• Low power listening modes
• Current consumption in 3-channel listening mode 1.7 μA (typ)
• Dynamic range 64dB
• 5 bit RSSI step (2dB per step)
• Clock Generator based on 32kHz XTAL, RC-OSC, or External Clock
• Operating temperature range -40 to +85ºC

Applications:

• Active RFID tags
• Real-time location systems
• Operator identification
• Access control
• Wireless sensors
