TD1050 GNSS Soc chips

TD1050 is a multi frequency, high-performance BDS/GPS/GLONASS/GALILEO/QZSS/SBAS/IRNSS satellite positioning and navigation timing chip. The chip adopts an integrated RF baseband design, integrating DC-DC, LDO, LNA, POR, RF processing, digital baseband processing, 32-bit RISC, CPU, ROM, RAM, Watchdog, Timer, RTC, etc. It supports UART, I2C, SPI, GPIO, external interrupt Exint, 1PPS, programmable TimeMark and other rich interfaces, as well as rich functions such as combined navigation, A-GNSS, D-GNSS, offline ephemeris calculation, etc. TD1050 adopts 28nm leading technology, which has high reliability, high performance, high integration, small size, low power consumption, low cost, anti-interference and other characteristics. It only requires a brief introduction of peripheral device interfaces to achieve complete GNSS receiver functions, reduce PCB area, and save hardware costs for users. It can directly replace mainstream GPS chips and greatly reduce replacement.
