Allystar Technology CO. Limited has launched multi-band multi-GNSS SoC with chip scale packaging helps portable devices save size and weight.
HD8040 dual band chip (WLCSPs)
Not only GPS, Galileo, but also Beidou, even the Indian IRNSS system and Japanese QZSS both use the L5 frequency. Accompanied more and more satellites supporting L1/L5 signals, Allystar offers HD8040 series chip set to fully support all civil signals on L5 band, said Shi Xian Yang, Allystar high precision product manager.
Besides L1 band, HD8040D supports L5/B2a/E5a already which are expected to have lower noise and better in multipath mitigation mainly due to the higher chipping rate of L5 signals relative to L1 C/A code.
HD8041D supports IRNSS(NavIC) which would be feasible and suited for navigation in urban areas in India and Middle East Area because there are seven NavIC satellites have a higher elevation than both GPS and Galileo satellites currently. This means IRNSS(NavIC) would provide greater accuracy, precision and available measuremts.
With the features of small size (3mm x 3mm) and low power consumption, HD8040 series is suitable for smartphone, tablets and portable devices.
The architecture integrates floating-point arithmetic units based on ARM CortexM4, 160 KB RAM, 32KB backup RAM with VBAT, 384 KB embedded FLASH. Besides basic peripheral interfaces UART, I2C, SPI, GPIO, it supports CAN interface for automotive application too.
Customer samples of the HD8040D and HD8041D are available now.
