TI – CC2650 Ultra Low Power 2.4 GHz Wireless MCU

  TI-CC2650-SimpleLink Ultra Low Power Wireless 2.4 GHz MCU

CC2650-SimpleLinkTM-1-Hardwre-Pro

 

Device Description

   The CC2650 device is a 2.4 GHz wireless MCU targeting Bluetooth Smart, ZigBee® and 6LoWPAN, and ZigBee RF4CE applications for remote control.

   The device is a member of the CC26xx family of cost-effective, ultra-low power, 2.4 GHz RF devices. Very low active RF and MCU current and low-power mode current consumption provide excellent battery life and allow for operation on small coin cell batteries and in energy-harvesting applications.

   The CC2650 device contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultra-low power sensor controller. This sensor controller is ideal for interfacing external sensors and for collecting analog and digital data autonomously while the rest of the system is in sleep mode. Thus, the CC2650 device is ideal for applications within a whole range of products including industrial, consumer electronics, and medical. 

   The Bluetooth Low Energy (BLE) controller and the IEEE 802.15.4 MAC are embedded into ROM and are partly running on a separate ARM Cortex-M0 processor. This architecture improves overall system performance and power consumption and frees up flash memory for the application. 

   The Bluetooth Smart and ZigBee stacks are available for free from Here.
