UFirebird UC6226_Ultra-low Power GNSS SoC | GPS/GNSS SoC | GNSS Devices | Positioning Chip | Products

Brief Introduction

With the 28nm process and UFirebird PMU design, UFirebird(UC6226/UC6228CI) features ultra-low power consumption and ultimate miniaturization, thus significantly improving the battery life. UC6226 is equipped with a built-in Sensor Hub which is capable of providing access for multiple sensors for fusion positioning. Through precise identification of the scene and context, it can ensure faster and more accurate positioning experience even in the harsh signal environment. UC6226 is developed for global application,and it supports BDS, GPS, GLONASS, Galileo, and it can achieve multquadi-system joint positioning. The high integration design reduces the quantity of peripheral devices and the board area. For QFN40 package, UFirebird complies with the AEC-Q100 reliability standard.
