RFID, RF Access, Monitoring ICS Procurement Notes

Verify the complete part number including suffixes such as MN6T/2 against official STMicroelectronics documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status through current datasheets or ECN notices. Cross-reference ordering information directly with manufacturer sources rather than distributor summaries to avoid discrepancies in variant details.

RFID, RF Access, Monitoring ICS Selection Notes

Choose this component when both wired I²C configuration and wireless NFC interaction are required within a single tag solution. Ensure system design accommodates the 2.7 V to 5.5 V supply range and SOIC-8 footprint. Consider thermal limits if operating near the upper temperature boundary, as write endurance decreases above 25°C. Validate antenna matching for the internal 25 pF capacitance requirement.

RFID, RF Access, Monitoring ICS Part Context

This device belongs to the ST25 family of NFC/RFID products by STMicroelectronics. It serves as a dynamic tag IC combining EEPROM storage with dual-mode connectivity. The M24SR64-Y series enables flexible integration into smart labels and interactive packaging where data updates occur post-manufacturing via NFC phones or dedicated readers.

RFID, RF Access, Monitoring ICS Replacement Considerations

Publicly confirmed substitutes include other variants within the M24SR64-Y series differing only in package or reel specifications, provided functional parameters remain identical. Verify pinout and electrical characteristics before substitution.
