1Chip Summary
The nanoNET chip is a low-power, highly integrated mixed signal chip uti-
lizing Nanotron’s unique wireless Chirp Spread Spectrum (CSS) communi-
cation technology.
This innovative modulation technique permits the development of chips
that have extremely low power consumption, operate over a wide range of
temperatures, and perform effortlessly in robust wireless networks operat-
ing in the 2.45 GHz ISM band.
This chip offers an ideal solution for battery powered applications that re-
quire a reliable and extremely long operating lifetime, such as several
years.
For communication over the air, CSS uses Upchirps and Downchirps with a symbol duration of Tsymbol = 1
µs and an effective bandwidth of Bchirp = 64 MHz.
A wide variety of systems and applications can be developed with this novel technology, with the additional
advantage of being able to select from data rates of either 500 kbps, 1 Mbps, or 2 Mbps.
Conveniently, only a minimal number of external components are required to build a fully operational bi-di-
rectional communication node.
