Short-range products in SO16N packages
CR14
The CR14 is a short-range contactless coupler fully compliant with ISO 14443. The coupler uses anti-collision mechanism. This complete solution combining the CR14 coupler and SRxx chips ensures total compatibility in protocol access.
CRX14
The CRX14 is based on the CR14, with additionnal France Telecom’s proprietary anti-clone function which ensures SRxx chips total compatibility in protocol access and features secure anti-counterfeiting
