Bluetooth 4.1 n/w processor operate at 1.7V supporting IoT

STMicroelectronics' new BlueNRG Bluetooth SMART network processor supports the latest Bluetooth version 4.1 enhancements and operate at 1.7V for longer-lasting battery-powered applications.

BlueNRG-MS network processor packs full Bluetooth PHY and 2.4GHz radio, ARM Cortex-M0 microcontroller running the Bluetooth 4.1 protocol stack, and dedicated AES-128 security coprocessor. API, power management, and Flash which are integrated offers direct connection to the application host controller through SPI bus with software partitioning between network processor and host microcontroller.

STMicroelectronics explains "The power efficient Bluetooth 4.1 specs supports dual-mode topologies containing devices operating as both master and slave. The new Low-Duty-Cycle Directed Advertising minimizes energy consumed when connecting to known devices. In addition, Bluetooth 4.1 introduces Logical Link Control and Adaptation Protocol (L2CAP), which enables flexible data exchanges leveraging multi-channel communications and quality of service." on the benefits of Bluetooth 4.1.

ST’s BlueNRG-MS network processor can be used in designing hub for collecting sensor data and transfer that data to smart phone. BlueNRG-MS supports the latest moves towards IP-based connectivity added to Bluetooth 4.1 supporting Internet of Things (IOT).

BlueNRG-MS is available now in a 5mm x 5mm x 1mm QFN32 package, priced from $1.50 for orders of 1000 pieces. A CSP option with the 2.6mm x 2.6mm footprint and the height as low as 0.56mm will be available after April 2015.
