RFID, RF Access, Monitoring ICS Procurement Notes

Verify component status as NRND (Not Recommended for New Designs) before procurement. Confirm package type matches the 8-TSSOP specification. Ensure compatibility with ISO 15693 protocols for intended RF interface requirements. Check datasheet revisions for any updates to electrical characteristics or pin configurations prior to integration.

RFID, RF Access, Monitoring ICS Selection Notes

Select this component when both I2C digital interface and ISO 15693 RF interface are required simultaneously. Consider the 4-Kbit EEPROM capacity for specific data storage needs. Evaluate the 1.8V to 5.5V operating range against system power constraints. Verify that the 13.56 MHz frequency aligns with regional regulatory standards for NFC operations.

RFID, RF Access, Monitoring ICS Part Context

This part belongs to the M24LR series of dynamic NFC/RFID tag ICs from STMicroelectronics. It shares architectural similarities with other members like the M24LR64E but offers lower memory capacity. The series is designed for applications requiring secure, contactless data exchange with embedded processing capabilities.

RFID, RF Access, Monitoring ICS Replacement Considerations

No public confirmed substitute part numbers are available. As the component is marked NRND, alternative solutions may require redesigning the interface logic to accommodate different memory architectures or communication protocols.
