Product Description
The Bluetooth low energy(BLE) chip used by FSC-BT671D includes a 32-bit 80 MHz ARM Cortex-M33 microcontroller, which can provide a maximum
power output of 20dBm. The chip's maximum receiving sensitivity is -97.5 (1 Mbit/s GFSK) dBm, and it supports a complete DSP instruction set and
floating point unit, which can speed up calculations. Low-power gecko technology supports fast wake-up time and energy-saving mode.
