Wireless microcontroller targets Bluetooth Smart applications

A member of the CC26xx family of cost-effective, ultra low-power, 2.4-GHz RF devices, the Texas Instruments (TI) CC2640 is now available from Farnell element14. The device features very low active RF and MCU current, and low-power mode current consumption, thus providing extra-long battery lifetime. This makes the CC2640 ideal for operation on small coin cell batteries and in energy-harvesting applications. The CC2640 contains a 32-bit ARM Cortex-M3 processor running at 48MHz as the main processor and a rich peripheral feature set, including a unique ultra-low power sensor controller, ideal for interfacing external sensors and collecting analogue and digital data autonomously while the rest of the system is in sleep mode. The Bluetooth Low Energy controller is embedded into ROM and run partly on an ARM Cortex-M0 processor. This architecture improves overall system performance and power consumption and frees up flash memory for the application.
