Product overview
The Unicore UFirebird IV UC7510A is an automotive-grade, single-frequency GNSS navigation and positioning chip from Unicore Communications, Inc. Built on a 22 nm process, it belongs to the UC7510 family intended for vehicle, drone and handheld applications. The family provides 64 channels and supports L1-band signals from BDS, GPS, GLONASS, Galileo and QZSS, along with SBAS reception and processing. It can position using multiple satellite systems together or a single system independently, with BeiDou-only and BeiDou-priority options.
UC7510A includes flash memory in a 4.0 × 4.0 × 0.75 mm QFN28 package and has an operating temperature range of -40°C to +105°C. Its automotive-grade chip qualification is AEC-Q100. The family incorporates interference mitigation and spoofing detection, and can integrate a dead-reckoning algorithm for use with an external IMU. Interfaces comprise one UART, one I2C and one SPI, with SPI support dependent on the firmware version. Available positioning update rates are 1, 5 and 10 Hz.
Integration requires V_IO and V_BACK supplies of 1.7–3.6 V and a V_CORE supply of 1.2–1.98 V. Family specifications give tracking sensitivity of -165 dBm and cold-start sensitivity of -148 dBm, with time to first fix below 26 seconds for a cold start, below 1 second for a hot start or reacquisition, and below 3 seconds with AGNSS. Positioning figures include 1.5 m horizontal accuracy with SBAS and 2.5 m vertical accuracy, although the product page labels these RMS while the product brief labels them CEP.
