Engineering Brief

The SLE 66R01P (my-d move) is a 152-byte EEPROM NFC chip compliant with ISO/IEC 14443-3 Type A and NFC Forum Type 2 Tag specifications, operating at 13.56 MHz with 106 kbit/s data rate. It features 128 bytes of freely programmable user memory organized in 38 blocks of 4 bytes, a 7-byte unique UID, configurable 32-bit password protection with retry counter, 32-bit OTP memory, per-block locking, and an optional 16-bit value counter with anti-tearing for ticketing applications. The chip supports both static and dynamic NFC memory structures (via lock/memory control TLVs), offers 100,000 erase/write cycles and 10-year data retention, operates from -25°C to +70°C, and is available in bare die, PG-TSNP-2-3 SMD package, or NiAu bumped wafer form factors. The SLE 66R01PN variant ships pre-configured in NFC INITIALIZED state with an empty NDEF message.

Frequently Asked Questions

How much user memory does the Infineon my-d move SLE 66R01P have?

The SLE 66R01P offers 128 bytes of freely programmable user memory out of 152 total bytes, organized in 38 blocks of 4 bytes each. This includes space for NDEF messages and application data.

Does the my-d move chip support password protection?

Yes, the SLE 66R01P features configurable 32-bit password protection with a retry counter. Password protection can be configured for read/write access or write-only access to secure memory content.

What is the anti-tearing feature on the SLE 66R01P?

The chip includes a 16-bit value counter with anti-tearing protection, designed specifically for ticketing applications. This ensures transactional integrity by preventing data corruption if the RF field is interrupted during a write operation.

Is the Infineon my-d move compatible with NFC smartphones?

Yes, the SLE 66R01P is fully compliant with NFC Forum Type 2 Tag specifications and ISO/IEC 14443-3 Type A, making it readable and writable by all NFC-enabled smartphones.

What is the difference between SLE 66R01P and SLE 66R01PN?

The SLE 66R01PN variant ships pre-configured in NFC INITIALIZED state with an empty NDEF message, while the standard SLE 66R01P requires manual NFC configuration. Both have identical memory and security features.

How many write cycles does the my-d move EEPROM support?

The SLE 66R01P EEPROM supports 100,000 erase/write cycles with 10-year data retention, suitable for applications requiring frequent updates like event ticketing or loyalty programs.
