WS8614P is based on the Dialog DA14580 Bluetooth 4.2 chip solution, which operates in the 2.4GHz frequency band and has a built-in Arm® Cortex-M0 microcontroller with 42kB SRAM and 32kB one-time programmable (OTP) memory. In addition, it has an onboard high-performance 8M-bit Flash to facilitate program development. The DA14580 has a fully integrated wireless transceiver and a baseband processor for Bluetooth low energy consumption. Its unique low-power architecture enables it to have extremely low power consumption, which allows it to run for a long time on a coin cell battery
