In cooperation with
Tego Inc. and
Easics, ICsense developed an
EPC RFID Class-1 Generation-2 UHF RFID compliant passive RFID tag. Particular about this development is the high memory of 32kbytes and the interface capabilities, which are non existing in current commercial tags that have maximally 512bits of memory. Moreover, the memory holds its data for more than 20 years due to careful memory - charge pump co-design. The tag gets its power from a UHF communication wave and use "backscattering" for communication. The power rectification of the 860-960 MHz carrier supplies worst-case only µWs, requiring state-of-the-art ultra-low-power design techniques. The IC has been integrated in a 0.18 µm CMOS technology. More information in the
Tego press release.
Features:
- High-efficient rectification of the 860-960 MHz carrier
- Ultra-low power analog (uWs)
- Power management
- Modulation (backscatter communication)
- Demodulation
- Ultra-low power clock ( MHz for less than 1 µA)
- High-efficiency memory write operation
