RFID, RF Access, Monitoring ICS Procurement Notes

Verify that the specific ordering suffix DA8/03J matches your required package type and tape/reel configuration. Confirm that the 4-byte NUID requirement aligns with your system's identification logic. Ensure the PLLMC interface specification meets your reader hardware constraints before finalizing procurement to avoid integration issues.

RFID, RF Access, Monitoring ICS Selection Notes

Select this component when migrating from MIFARE Classic without changing reader infrastructure. It is suitable for applications demanding higher security than standard MIFARE Classic but requiring identical memory mapping. Consider this part if a 1Kb capacity and 4-byte UID are sufficient for your data storage and identification needs.

RFID, RF Access, Monitoring ICS Part Context

This IC belongs to the MIFARE Plus SE family, designed to bridge the gap between legacy MIFARE Classic and modern MIFARE DESFire technologies. It allows operators to upgrade security levels in deployed systems without replacing existing readers, maintaining operational continuity while enhancing protection against cloning and eavesdropping attacks.

RFID, RF Access, Monitoring ICS Replacement Considerations

Direct substitutes include other variants within the MIFARE Plus SE series, such as those with different memory sizes or NUID lengths. Verify pinout and software compatibility when considering alternative NXP smart card ICs to ensure seamless replacement in existing designs.
