Key Benefits

  • Bluetooth® Low Energy (LE) 4.0 and 4.1 for power sensitive applications
  • Flexible system architectures through:
    HCI model over UART
    Embedded profile model (API over host UART)
    Stand alone model (with embedded stack and  profile)
  • Bluetooth® qualified embedded BLE stack and GATT profile for easy BQB EPL
  • On-chip RAM for slow to medium size applications
  • Ultra low bill of materials due to very few external components
  • System integration by multiple on-chip peripherals
  • Supports over-the-air (OTA) update of system software
  • Flexible single power supply (1.8V-3.6V)
  • Various sleep modes and clock options to optimize power consumption
  • Small and cheap system design with QFN40 package and CSP package
