SAMB11 QFN SOC Ultra-low Power BLE 4.1 SoC DATASHEET Description The SAMB11 is an ultra-low power Bluetooth SMART (BLE 4.1) System on a Chip with Integrated MCU, Transceiver, Modem, MAC, PA, TR Switch, and Power Management Unit (PMU). It is a standalone Cortex -M0 applications processor with embedded Flash memory and BLE connectivity. The qualified Bluetooth Smart protocol stack is stored in dedicated ROM, the firmware includes L2CAP service layer protocols, Security Manager, Attribute protocol (ATT), Generic Attribute Profile (GATT) and the Generic Access Profile (GAP). Additionally, application profiles such as Proximity, Thermometer, Heart Rate, Blood Pressure, and many others are supported and included in the protocol stack.
