Bluetooth Low Energy Products

Bluetooth® low energy technology is an integral part of the Bluetooth Core Specification from Bluetooth v4.0 onwards. Bluetooth low energy brings Bluetooth wireless connectivity to low cost, small battery operated devices that require months to years of battery lifetime. Bluetooth low energy will therefore enable a new and extended range of applications to benefit from Bluetooth wireless technology including watches, proximity tags, sports and fitness sensors, healthcare sensors and remote controls.

Bluetooth low energy technology can be branded under the Bluetooth smart marks in accordance with guideline from the Bluetooth SIG.

The nRF51822 is a powerful, highly flexible multi-protocol SoC ideally suited for Bluetooth® Smart (previously called Bluetooth low energy) and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB flash + 16kB RAM. The embedded 2.4GHz transceiver supports Bluetooth Smart as well as 2.4GHz operation, where the 2.4GHz mode is on air compatible with the nRF24L series products from Nordic Semiconductor.

nRF51822 also incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interconnect (PPI) system. A flexible 31-pin GPIO mapping scheme allows I/O like serial interfaces, PWM and quadrature demodulator to be mapped to any device pin as dictated by PCB requirements. This enables complete design flexibility associated with pin-out location and function.

nRF51822 supports Bluetooth Smart protocol stacks as well as 2.4GHz protocol stacks, including Gazell, both available free of charge. nRF51822 requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8-3.6V, a direct 1.8V mode and a on chip DCDC buck converter giving a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enablesnRF51822 to operate at radio peak currents below 10 mA @ 3V supply (TX @ 0 dBm & RX).

nRF51 SDK provides extensive software support for both Bluetooth Smart and 2.4GHz proprietary applications.

nRF51822 is available in 6x6mm 48-pin QFN packages and 3.5x3.8mm 64 ball wafer-level chip-scale packages (WLCSP).

nRF51822 is available in either 256k or 128kB Flash size variants.

Nordic Semiconductor protocol stacks are known as SoftDevices. SoftDevices are pre-compiled, pre-linked binary files. SoftDevices can be programmed in nRF51 series SoCs and are downloadable from the Nordic web.

The nRF51822 supports the SoftDevices below (click on the icons for details).

they intend it to be used in wearables as well as other places.

commentary-  Almost ALL wearables so far use the smartphone for any connection to the cloud.  So sensors transmit the data to the on board sensor hub for fusion and communication to the smartphone would be via BLE.  Nordic want to be this connectivity and

I wondered how QUIK would get this important piece and with this dot they will use the above silicon for its project.  

They will make a nice pairing....

Would they ever go together on a SoC one day,  aqs the wearables will go SoC next yr and the sensor hubs will get BLE on them.  WiIll track along.
