- Low power, small size, and high performance enable widespread
deployment of energy-conscious, space-constrained applications with
BLE connectivity
- Provides state-of-the-art security and is Bluetooth
5.0-certified to ensure interoperability with the latest mobiles
and tablets
Geneva, June 28, 2017 - The new-generation Bluetooth® Low
Energy (BLE) System-on-Chip from STMicroelectronics (NYSE: STM), a
global semiconductor leader serving customers across the spectrum
of electronics applications, is set to accelerate the spread of
connected smart objects throughout homes, shopping areas, industry,
toys and gaming, personal healthcare and infrastructure.
Built into all new mobile phones, tablets, and computers,
Bluetooth Low Energy wireless technology enables consumers to
interact with any BLE-enabled object from their own devices.
Similarly, service providers can conveniently connect assets to the
Cloud for service delivery and data collection.
ST sees important opportunities for BLE-connected applications
that are simple, functionally focused, and can operate on
a button cell for months or years. The new BlueNRG-2 chip
meets all these needs with its extremely power-efficient
programmable processor and low-power features including an
ultra-frugal standby mode. The high RF signal strength saves system
power by ensuring reliable wireless communication, and generous
on-chip memory for BLE software and application code simplifies
system design by saving external memory components. BlueNRG-2 is
Bluetooth 5.0-certified, which ensures interoperability with the
latest generation of smartphones, and supports enhanced features
such as state-of-the-art security, privacy, and extended packet
length for faster data transfer.
"The BlueNRG-2 ushers in an era of connected smart things all
around us, enabling secure, reliable and energy-efficient
interaction with any object, like a toothbrush or lighting switch,
from our mobile devices," said Benedetto Vigna, Executive Vice
President, Analog and MEMS Group General Manager,
STMicroelectronics. "Moreover, the objects can benefit from simple
construction, fully sealed if necessary, and yet fully
interoperable through natural voice control or the feature-rich and
stylish user interface of an Android or iOS smart application."
A comprehensive Software Development Kit (SDK) is available,
featuring the BlueNRG Navigator Graphical User Interface (GUI),
which makes it extremely easy for designers and innovators to
create the next generation of connected devices with the BlueNRG-2
chip and realize the vision for a smarter environment.
BlueNRG-2 is available now, in a 32-pin QFN. Further options
will be introduced later in the year, offering more GPIO in a
48-pin QFN and an ultra-small 2.6mm x 2.7mm WLCSP chip-scale
package. Budgetary pricing for the BlueNRG-232 (QFN package) is
$1.95 for orders of 1000 pieces. The SDK can be downloaded free of
charge from www.st.com/stsw-bluenrg1-dk-pr
Further technical information:
ST has chosen the ARM® Cortex®-M0 core to provide low-power,
extremely efficient, 32-bit processing performance for BlueNRG-2.
Other integrated features include cryptographic processing, power
management, clock management, and up to 256KB of Flash memory
giving extra flexibility to handle code and data storage. Multiple
power-saving modes, including standby mode drawing just 0.5µA, help
meet functional requirements with a minimal power budget. The
integrated BLE radio with +8dBm RF output power maximizes
communication range and saves overall energy consumption by
avoiding data errors and retries. The device is specified for
operation up to 105°C, allowing use in a wide range of scenarios
including automotive environments.
Developers using BlueNRG-2 can also take advantage of seamless
interconnection with the ST MEMS sensor portfolio, which includes
market-leading accelerometers, gyroscopes, magnetometers, Inertial
Measurement Units (IMU), pressure sensors, and other environmental
sensors. An integrated 2-channel, 10-bit analog-to-digital
converter (ADC) provides a convenient interface for analog
front-end transducers, and a Pulse Digital Modulation (PDM)
interface simplifies connecting a digital MEMS microphone for
natural-speech voice-controlled applications. The increased memory
size and the high-efficiency core architecture allows running ST
Open.MEMS libraries with low impact on the overall power
consumption. The sensors and libraries, together, enable developers
to implement advanced capabilities such as gesture recognition and
activity tracking.
ST has also developed a dedicated ultra-miniature balun
(BALF-NRG-02D3) for its BlueNRG devices. Integrating a matching
network and harmonics filter, the enhanced balun simplifies RF
complexity and provides optimized link budget in a less than 1.2
mm² footprint. Designed on non-conductive glass substrate, it
offers low dispersion over temperature, surpassing other solutions
available in the market.
The BlueNRG Navigator GUI simplifies and streamlines device
configuration, setup and testing, and enables makers or developers
to quickly get started and implement new ideas for smart devices
without requiring any specific RF or BLE skills. The intuitive
graphical interface enables users to become productive in just a
few hours. Application examples, code snippets, and versatile tool
support allows coding to begin quickly using the BlueNRG-2
Evaluation Kit.
The BlueNRG-2 Evaluation Kit (STEVAL-IDB008V1) contains MEMS
sensors, LEDs, push-buttons, and programming interfacing to run the
provided demonstration software out-of-the-box. An
Arduino-compatible connector is also featured on-board, which
allows development of more complex applications by adding extra
expansion boards.
