Engineering Brief

The LEGIC ATC256 is a dual-standard HF chip supporting both ISO/IEC 14443-A for broad NFC/reader compatibility and LEGIC's proprietary RF protocol for enhanced security and multi-application segmentation. With 256 bytes of user memory organized into secure segments, it is well-suited for access control and ticketing systems requiring both interoperability and LEGIC's native security features. Engineers integrating this chip should plan for dual-protocol reader support and leverage LEGIC's segment-based access rights for multi-tenant or multi-application deployments. Its compact die form factor makes it suitable for embedding into cards, fobs, and wearables.
