AS3933-BTST RFID应答器

AS3933-BTST

RFID应答器 3D Low Power Wakeup Receiver

General Description

The AS3933-BTST AS3933 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 15-150 kHz. The integrated correlator can be used for detection of a programmable 16-bit or 32-bit Manchester wakeup pattern. The device can operate using one, two, or three active channels.
