FSC-BT677D Bluetooth low energy chip incorporates a 32-bit 80 MHz ARM Cortex-M33 microcontroller, delivering a maximum power output of 20 DBM. It features a high sensitivity of -97.5 DBM (1 Mbit/s GFSK) and includes a DSP instruction and floating-point unit for efficient signal processing. Utilizing low-power gecko technology, it ensures fast wake-up times and energy-saving modes. The chip’s software and SDK support Bluetooth Low Energy (LE), Bluetooth 5.2, and Bluetooth mesh network, alongside compatibility for developing proprietary wireless protocols. This module is ideal for battery-operated applications requiring both high performance and low energy consumption.
