Allystar Technology Co. Ltd. has launched a multi-band, multi-GNSS system on chip, the HD8040 series, to help portable devices save size and weight. The HD8040 offered in wafer-level chip-scale packaging (WLCSP).

The HD8040 series of chipsets fully supports all civil signals on the L5 band, said Shi Xian Yang, Allystar high-precision product manager at Allystar. Besides GPS, other constellations with L1/L5 signals include Galileo, BeiDou, the Indian NavIC system and Japanese QZSS.

Besides L1 band, HD8040D supports L5/B2a/E5a signals, which are expected to have lower noise and be 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 makes it suitable for navigation in urban areas in India and the Middle East, where seven NavIC satellites have a higher elevation than both GPS and Galileo satellites. This means IRNSS (NavIC) would provide greater accuracy, precision and available measurements.

With the features of small size (3 x 3 millimeters) and low power consumption, the HD8040 series is suitable for smartphones, tablets and other portable devices.

The architecture integrates floating-point arithmetic units based on ARM CortexM4, 160 KB RAM, 32 KB backup RAM with VBAT, and 384 KB embedded Flash memory. Besides basic peripheral interfaces UART, I2C, SPI and GPIO, it supports the CAN interface for automotive applications, too.

Customer samples of the HD8040D and HD8041D are available now.
