CSR1011

CSR1011

Qualcomm® CSR1011 QFN is a Qualcomm® Bluetooth Low Energy platform technology. Qualcomm Bluetooth Low Energy supports ultra low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. CSR1011 QFN is designed to provide virtually everything required to create a Bluetooth Low Energy product with RF, baseband, MCU, qualified Bluetooth v4.1 specification stack and customer application running on a single IC.

Qualcomm CSR1011, Qualcomm CSR101x, CSRmesh and Qualcomm Bluetooth Low Energy are products of Qualcomm Technologies, Inc., and/or its subsidiaries.
