Irvine, Calif. — Broadcom Corporation released a new global navigation satellite system (GNSS) chip for the Internet of Things (IoT) and wearable devices. The advanced chip enables devices such as fitness bands to deliver pinpoint location while consuming minimal power, and, in some cases, can eliminate the need for a separate microcontroller, said Broadcom.
The BCM47748 removes a bulk of the signal processing from the device microcontroller (MCU) by calculating position, velocity and time (PVT) on-chip, which delivers a significant system power savings, said Broadcom. The chip uses intelligent firmware to extend battery life while also maintaining accuracy in speed, distance and position for an enhanced user experience.
By performing location computations on-chip, Broadcom said it not only reduces power consumption but also can significantly lower costs by replacing the device MCU and reducing board space. The firmware inside the BCM47748 automatically adapts to user activity and context, whether biking, walking or running, to provide precise location results to the user.
Availability: The Broadcom BCM47748 (70 ball WLBGA package with 0.4mm ball pitch) is currently sampling with customers. Evaluation kits and reference designs are also available.
