Frequently Asked Questions

What is the memory capacity of LEGIC MIM256 and MIM1024 chips?

The LEGIC MIM256 has 256 bytes of memory, while the MIM1024 offers 1024 bytes. Both variants operate on the same 13.56 MHz LEGIC prime protocol with compatible architectures.

What security features does the LEGIC MIM chip offer?

The chip provides encrypted data transmission, a unique non-erasable and non-duplicable UID, licensee identification, and individually programmable read/write protection per memory segment. It uses a proprietary LEGIC authorization concept for secure access control.

What is the operating frequency of LEGIC MIM chips?

LEGIC MIM256 and MIM1024 chips operate at 13.56 MHz using the LEGIC prime contactless protocol for RF communication.

Can LEGIC MIM chips support multiple applications on one card?

Yes, the MIM (Memory-in-Memory) architecture with variable-length segments is specifically designed for multi-application deployment. Each segment can have individual read/write protection settings, allowing different applications to coexist securely on a single chip.

What form factors are available for LEGIC MIM chips?

LEGIC MIM chips are available as wafer or MCC2-module formats, suitable for integration into contactless cards, watches, keys, and various tag form factors.

Is the LEGIC MIM compatible with ISO 14443 or ISO 15693 standards?

No, LEGIC MIM chips use the proprietary LEGIC prime protocol at 13.56 MHz and are not compatible with ISO 14443 or ISO 15693 standards. They operate within the LEGIC ecosystem.
