Shenzen-based Chinese GNSS chipsets developer, Allystar Technology, has introduced a multi-band GNSS SoC with Wafer-level Chip-Scale Packaging (WLCSP). The new HD8040 GNSS chipset will enable compact and lightweight devices to be developed.
The global GPS frequency band, L5 frequency, is used by not only GPS, Galileo and Beidou, but also by India’s IRNSS and Japan’s QZSS navigation systems. With more and more satellites supporting L1/L5 signals, Allystar developed the new HD8040 GNSS series chipset to fully support all civil signals on the L5 band. Besides the L1 band, the HD8040D supports L5/B2a/E5a already which are expected to have lower noise and better multipath mitigation mainly due to the higher chipping rate of L5 signals relative to L1 C/A code.
The new GNSS chipset supports the IRNSS (Indian Regional Navigation Satellite System) – NavIC, which would be feasible and suited for navigation in urban areas in India and Middle East Area because there are seven NavIC satellites that have a higher elevation than both GPS and Galileo satellites currently. This means IRNSS would provide greater accuracy and precision.
With its compact size (3mm x 3mm) and low power consumption, the HD8040 series is suitable for smartphone, tablets and portable devices. The architecture integrates floating-point arithmetic units based on ARM CortexM4, 160 KB RAM, 32 KB backup RAM with VBAT, 384 KB embedded FLASH. Besides basic peripheral interfaces UART, I2C, SPI, GPIO, it supports CAN interface for automotive application too.
