Atmel ATBTLC1000超低功耗蓝牙SMART (BLE 4．1)解决
方案
Atmel公司的ATBTLC1000是超低功耗蓝牙SMART (BLE 4.1)系统级芯片(SoC),集成了ARM? Cortex?-M032位MCU,收发器,调制解调器,MAC,PA,TR开关和功率管理单元(PMIC),可用作蓝牙低功耗连接控制器或数据泵,或嵌入了BLE连接和外接存储器的单独应用处理器,主要用在医疗电子如血氧仪,心率仪,血压计,体温计等.本文介绍了ATBTLC1000主要特性,框图,以及ATBTLC1000-MR110CA模块框图,电路图和材料清单以及BTLC1000 Xplained Pro扩展评估板主要特性.
The Atmel? ATBTLC1000 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 can be used as a Bluetooth Low Energy link controller or data pump with external host MCU or as a standalone applications processor with embedded BLE connectivity and external memory.
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.
