Bluetooth Low Energy - BDE-LE2640R2LAU(Bluetooth 5.0 Low Energy Based on CC2642R2L)
  • BDE-LE2640R2LAU(Bluetooth 5.0 Low Energy Based on CC2642R2L)
  •  
    General Description

    LE2640R2LA is a Bluetooth 5.0 single-mode compliant Bluetooth low energy module targeted at low power sensors and PC/Phone accessories. LE2640R2LA0/LE2640R2LA4/LE2640R2LA8 corresponds to three flash modules of different sizes. LE2640R2LA highly integrates Bluetooth Low Energy radio, stack, profiles and applications in a SoC, without the need of using an external MCU. The module also offers flexible hardware interfaces for the sensor application. It enables ultra-low power connectivity and data transfer for the applications that are sensitive to power consumption, size and cost.
