LEGIC advant and MIFARE DESFire EV2
combined in one chip

ATC4096-MP312 belongs to LEGIC's advant smartcard ICs.

Based on the NXP DESFire EV2 8k chip, the new smartcard IC provides 4k byte for LEGIC advant and 3.3k byte of memory are reserved for future DESFire applications.
The chip will be compatible with the NXP AppXplorer and has about 20% more reading distance than an EV1 chip.
The hardware of the ATC4096-MP312 is certified according to Common Criteria EAL5+ and used in projects with high security requirements.

Powerful smartcard ICs

LEGICs advant smartcard ICs offer powerful, reliable and security compliant quality for contactless RFID solutions. LEGICs perfectly coordinated interaction between smartcard IC and reader IC enables fast and seamless integration into a wide variety of applications.

Security & encryption

Smartcard ICs come with pre-configured, confidential key material as a standard and can be customized to meet customer requirements. LEGIC advant uses modern encryption methods and supports with the MTSC (Master-Token System-Control) a unique security and authorization solution with scalable security.

Replacement for hybrid cards

Hybrid cards can be the reason for interferences, compatibility problems and other inconveniences. Thanks to the combination of LEGIC advant and MIFARE DESFire in one chip, expensive hybrid cards will be a thing of the past. The powerful ATC4096-MP312 will enable a smooth integration in various multi-technology applications.
