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.
