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.
