The GP570 IEEE 802.15.4/Bluetooth® Low Energy (LE) Communications Controller provides a fully integrated solution for ultra-low power wireless communications, with fully integrated IEEE 802.15.4 and Bluetooth Low Energy software stacks that enable fast and simple integration. It is optimized for low cost while providing superior performance. It is compliant with the IEEE Standard 802.15.4 and the Bluetooth Core Specification version 4.2 for Bluetooth Low Energy, providing robust spread spectrum data communication with a highly secure encrypted data flow. For IEEE 802.15.4 communications, antenna diversity offers additional robustness in a crowded wireless 2.4 GHz environment.

The GP570 features a radio transceiver, integrated real-time Medium Access Control and Bluetooth Low Energy controller, integrated Arm® Cortex® M4 microprocessor, RAM and Flash memory, security engine, event scheduler, and an extensive set of peripherals. The GP570's integrated RF baluns and filters reduce the product's RF design complexity enabling very low cost single layer applications using simple PCB antennas requiring no shielding and a minimum number of external components. The Flash memory allows for software upgrade over the air.

Advanced power management features ensure that power consumption is minimized in active as well as in standby states, enabling maintenance free and very small form factor products. For lower power consumption, the integrated DC/DC Buck converter can be used together with a few external components. Alternatively, the internal regulator can be used instead of the integrated DC/DC converter, to minimize the bill of material.
