Topaz

Topaz - 13.56MHz - ISO 14443A - 96 bytes read/write NFC/RFID IC mandated by NFC Forum as the Type 1 NFC Forum Tag Format.

Part Number - IRT5011W

Key Benefits -

Small die size ensures Topaz is suited to applications where unobtrusive positioning is important and where integration into other chipsets may be required
Low power requirement
Ideally suited to NFC tags/smartposter/one-touch set-up applications
Mandated as Type 1 Tag Format by the NFC Forum ensures interoperability with standards mandated devices
"Read all" command enables entire content of Topaz tag to be read in one shot, rather than a block at a time, which give superior read performance
Follows ISO/IEC 18092 and ISO/IEC14443-3 standards
Will operate with forthcoming ISO/IEC 18092 & ISO/IEC21481 based NFC devices directly
Offers 96bytes of read/write memory, twice as much as nearest comparable competitor product, a crucial memory advantage for the smartposter use case model
Anti-tear protection is facilitated by using shadow memory blocks

Topaz Features -

Topaz IC is for use in NFC Tags/Smartposter/One-touch Setup applications as well as general ISO/IEC14443A based RFID applications
Targeted for operation with NFC devices which work to ISO/IEC18092 (NFCIP-1) and/or ISO/IEC21481 (NFCIP-2)
Designed to be compatible with ISO/IEC14443 parts 2 and 3
ISO/IEC14443 type A modulation scheme
Passive RFID tag operating in the unlicensed 13.56MHz band
Read and Write (R/W) operation
One Time Programmable (OTP) & Write Once Read Many (WORM) operation
Typical operating range up to 10cm depending on tag/reader antenna coil sizes and orientation relative to the reader unit
Fast data communication rate 106 kbit/s
UID provision in Topaz IC to enable collision detection by means of the Reader/Writer issuing a RID (Read UID) command
Protection for data during the write operation by the Topaz IC only responding to commands prepended by a matching UID. This also provides protection in the situation where there are multiple tags in the field
Fast byte write speed
Data communications are protected by 16-bit CRC integrity checking
EEPROM based user read/write memory area organised as 12 blocks of 8-bytes
7-bytes of Unique Identification (UID) number for use in data authentication /anti-cloning
96-bytes of user read/write memory
6-bytes of OTP memory
All memory areas are individually one time lockable by RF command to prevent further modification of data and to produce read only functionality

Topaz Benefits in more detail -

Small dies size
Mandated as Type 1 Tag Format by the NFC Forum for operation with NFC devices in Reade/Writer mode
Initial "Request and Answer" communication cycle between the NFC reader/writer device and the Topaz IC based NFC Tag follows the ISO/IEC18092 and ISO/IEC14443-3 standards
Will operate with forthcoming ISO/IEC18092 & ISO/IEC21481 based NFC devices directly and with typical existing ISO/IEC14443 reader/writers after software modification only
Low power requirement
High-interity - 16-bit CRC protection on communications protocol
Blocks of memory can be utilised as shadow areas for anti-tear protection measures
Memory size and capacity is scalable for custom designs
Two bond pad die attachment
Wire-bond, flip chip and module die attachment methods possible
Suitable for operation with wide variety of antenna coil size, form factor and construction
Fast read command (RALL) saves testing time
