UHF RFID sensor IC : AS3213C + AS3212 external

AS3213C

External sensor with Capacitive Analog Interface.

AS3213C is an EPCTM Class-1 Generation-2 compliant IC for UHF RFID applications. The chip offers advanced performance in sensor acquisition mode, due to an ultra-low power internal acquisition channel. It can be powered either by a battery or by the RF energy transmitted from a reader. In a Battery Assisted Passive (BAP) configuration, the AS3213C offers an increased reading range compared to passive RFID solutions.
