Thought I'd give an introduction to the Bluetooth Low Energy (BLE) peripheral in PSoC 6 BLE MCUs. The PSoC 6 BLE MCU incorporates a Bluetooth Smart subsystem that contains the Physical Layer (PHY) and Link Layer (LL) engines with an embedded security engine. The physical layer consists of the digital PHY and the RF transceiver that transmits and receives GFSK packets at 2 Mbps over a 2.4-GHz ISM band, which is compliant with Bluetooth Smart Bluetooth Specification 5.0.



  • 2.4-GHz RF transceiver with 50-Ω antenna drive
  • Digital PHY
  • Link Layer engine supporting master and slave modes
  • Programmable output power: up to 4 dBm
  • RX sensitivity: –95 dBm
  • RSSI: 1-dB resolution
  • 4.2 mA TX (0 dBm) and 4.4 mA RX (2 Mbps) current with 3.3-V battery and internal SIMO Buck converter
  • Link Layer engine supports four connections simultaneously
  • Supports 2 Mbps LE data rate

Happy reading!
