GENERAL DESCRIPTION
AS3909/AS3910 13.56 MHz RFID Reader IC, ISO-14443 A/B Additionally using this configuration means half of the power consumption at the same output power. The IC has an operating voltage down to 2.4V and a low power operating mode of 5mA. This means the AS3909/10 is ideal for portable or battery powered applications. For applications where high power is required the AS3909/10 can attain up to 700mW. This means there is no need for complex external booster circuitry. The component count and complexity of the design is further reduced through the patented automatic modulation depth adjustment. The analog front end (AFE) is complemented by a highly integrated data framing engine for both ISO-14443 A and B. This includes data rates up to 848kbits with all framing and synchronization tasks on board. This enables the customer to build a complete HF RFID Reader using only a low end micro. The AS3909/10 not only supports reader to tag communication, but sports Peer to Peer communication using the NFCIP-1 active communication mode with a data rate of 106kbps.
