Based on ultra-low power impulse radio technology by imec and Holst Centre, the new chip uses the ultra-low power ‘impulse-radio’ (IR) developed by imec and Holst Centre which enables real-time 3D location information that is accurate to within 10 cm.

The device combines digital processing elements and sophisticated analog radio functionality in a single chip, enabling superior performance at a low cost of ownership. It can operate in both the 3.1-4.8 GHz and 6-10 GHz bands for use around the world and seamless co-existence with other wireless technologies.

Moreover, with an operating voltage range of 1.5 to 3.6 V, the chip is ideal for battery-powered applications. Together with its small form factor and low power consumption, this makes it suitable for integration into tags, wireless sensors, base stations and mobile devices. A base station equipped with BlinkSight’s technology could track and trace thousands of fast moving tags in real time. In addition the tags are interactive and capable of sending dynamic data (e.g. temperature).
Fabricated in standard 90 nm RF-CMOS, the chip is manufactured at TSMC in Taiwan. It features an embedded software-programmable ultra-low power 128 bit vector DSP drawing less than 16pJ/cycle and offers a range greater than 60m in line of sight, or greater than 20m when not in line of sight. It could operate over five years from a standard coin battery.
