FSC-BT618 CC2642R BLE 5.2 Module

Tags: , ,

FSC-BT618 is a wireless microcontroller (MCU) BLE module targeting Bluetooth 5.2 Low Energy applications. Very low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications. FSC-BT618 contains a 32-bit ARM® Cortex®-M4F core that runs at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultra-low power sensor controller. This sensor controller is ideal for interfacing external sensors and for collecting analog and digital data autonomously while the rest of the system is in sleep mode. Thus, FSC-BT618 is great for a wide range of applications where long battery lifetime, small form factor, and ease of use is important. It supports GAP, ATT/GATT, SMP, and L2CAP profiles. It integrates Baseband controller in a small package (Integrated chip antenna), so the designers can have better flexibilities for the product shapes.
