Unicore UFirebird IVTM chip (see Product Models of UC7510) features 22 nm process with low power consumption and ultra-small form factor, significantly increasing the battery life of users’ device.
UC7510 is suitable for global applications. It supports L1 band of GPS, GLONASS, BDS,Galileo and QZSS multi-constellation joint positioning, and supports the reception and processing of multiple SBAS signals, providing users with fast, accurate and highperformance positioning experience.
UC7510 is highly integrated, with built-in LDO, LNA, RTC, etc. It can provide the function of a complete GNSS receiver with only a few external components, significantly reducing the PCB area and hardware costs for users.
The sub-model UC7510A-01 supports connection of various sensors such as gyroscopes, accelerometers, and odometers for fusion positioning. With the built-in DR (dead reckoning) algorithm, the chip can directly output GNSS + MEMS integrated positioning results, enabling continuous positioning even in tunnels and underground garages.
