TegoChip™ – Rugged High-Memory RFID
Tego chips enable major advances in both where and how RFID technology is deployed.
Devices are fully compatible with ISO/IEC 18000-6 Type C (EPCglobal Gen 2),
while incorporating significant feature increases as follows:
- High memory up to 32Kbytes;
- Ability to withstand high temperatures and gamma radiation;
- 100+ year memory life;
- I2C interface and power out to other devices;
- Passive and semi-passive modes;
- Optimal support for ATA Spec 2000 without optional or proprietary commands.
Chips are available in several form-factors as follows:
- Wafer — for flip-chip and wirebonding assembly;
- QFN/TQFP — for surface mount assembly;
- Murata MagicStrap™ — coming soon ... sample quantities.
Chips are also available in three families optimized for different applications as follows.
XL - Long-life, high-memory application in harsh environments
The XL series is used by tag manufacturers for high-memory applications in harsh environments. Key features of the XL chip include:
- High memory options from 2K up to 32Kbytes;
- Durable for use in high temperatures and gamma radiation;
- Extra long memory life up to 100+ years;
Chips in this series are as follows:
- TegoChip 2000
A new addition to the XL Extra Long-Life family, TegoChip 2000 supports extended memory EPC.
- Radion Chip
The first Gen 2 UHF tag capable of surviving repeated gamma-sterilization and other intense radiation exposure.
- TegoChip XLT
he first passive, high-memory UHF chips chosen by Airbus for use in tagging flyable parts on the A350XWB. Supports memory storage from 2k to 32Kbytes.
XM - High-memory application in benign environments
The XM series is used where a high memory is required in benign environments, such as smart card and security applications.
Its high memory capacity makes it ideal for storing biometric data, and for security memory payload is sufficient
to accommodate NSA Suite B encryption up to top secret levels. This chip allows organizations deploying UHF RFID elsewhere
to extend that infrastructure to personal access control and other security sensitive applications.
GW - Interface to sensors, controls and displays via I2C
The GW series is used to manage devices such as sensors, controls and displays via an I2C interface, as in the example
of the VRF tag shown here where the TegoChip is used to change the display using a standard Gen 2 reader.
The GW chip has a number of unique characteristics compared to other devices as follows:
- High memory up to 32Kbytes;
- Usable in harsh environments;
- Ability to power external devices using harvested RF power;
- Passive and semi-passive modes.
