Humbird UC221

GPS/BDS GNSS Positioning SoC

Brief Introduction

Unicore UC221 is a GPS/BDS high performance low-power GNSS SoC, which features single chip architecture (RF+BB) to provide users with ultra low power consumption, ultra high-performance location service and user experience.
UC221 supports single system independent positioning and BDS+GPS dual-system interoperation, and is flexible for configuration. With unique “Ultra-Sense” high sensitivity base-band design, the receiver can remain well positioning effect in the urban canyon and other complex environment. At the same time, thanks to innovative “Rhythm Sleep” technology, UC221 can run at very low power levels. The simple, compact design makes it most suitable for portable navigation, personal tracking, and other consumer and automotive applications.

Advantage

• Single chip solution, baseband and RF integrated
• Support BDS+GPS dual-system interoperation,also BDS or GPS single system independent positioning
• Both 26MHz and 16.369MHz TCXO supported
• Low cost design and simple eBOM needed
• 6mm×6mm×1.2mm, FBGA64
