HF Reader System Series 6000
S6700 Multi-Protocol Transceiver IC
The S6700 Multi Protocol Transceiver IC enables a broad range of 13.56MHz
RFID interrogator designs for portable and stationary readers. This low power
consumption device supports multiple RF communication protocols, minimizes
onboard power requirements and reduces parts count in a final reader product.
