Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix for package type; 'LM' denotes the Module Contactless Card (MCC2-2-1), while 'C' indicates the die version. Confirm availability status as the product information dates from January 2001. Ensure compatibility with existing reader infrastructure supporting ISO/IEC 14443 Type A protocols before procurement.

Application Specific Microcontrollers Selection Notes

Select this component when a secure, contactless memory solution with anti-tearing counters is required. The configurable sector structure allows flexibility between single large sectors or multiple smaller ones. Verify that the system design includes a Security Access Module (SAM) for performing mutual authentication and MAC calculations on protected memory areas.

Application Specific Microcontrollers Part Context

The SLE 55R04 belongs to the SLE 55Rxx family of contactless memory chips designed for high security and flexible memory configuration. This family addresses variable application needs through different memory sizes. The SLE 55R04 specifically targets applications demanding both cost-effective memory access and robust security features like hierarchical key management.

Application Specific Microcontrollers Replacement Considerations
