Power management solution for Bluetooth Low Energy IoT applications reduces Nordic SoC sleep mode power consumption increasing battery life up to 10x

Courtesy of Nordic Semiconductor : Power management solution for Bluetooth Low Energy IoT applications reduces Nordic SoC sleep mode power consumption increasing battery life up to 10x

Nanopower’s ‘nP-BLE52 module’ can reduce the power consumption of Nordic’s nRF52832 SoC to 10nA in sleep mode and wake up the chip on a predetermined schedule or based on sensor threshold values

Nordic Semiconductor today announces that Skien, Norway-based Internet of Things (IoT) developer, Nanopower, has selected Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) to provide the wireless connectivity for its ‘nP-BLE52 module’, designed for developers of IoT applications with highly restricted power budgets.

The nP-BLE52 module employs a proprietary power management IC—integrated alongside Nordic’s nRF52832 Wafer-Level Chip Scale Package (WL-CSP) SoC in a System-in-Package (SiP)—which enables it to cut power to the SoC, putting it in sleep mode, before waking it up a pre-set time and in the same state as before it was put to sleep. In doing so the SoC’s power consumption in sleep mode is reduced to 10nA, making it ideal for IoT applications where battery life is critical by potentially increasing cell lifespan 10x.

In active mode, the nRF52832 SoC runs normally. The SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system. Once the Nordic SoC has completed its tasks, it instructs the nP-BLE52 to put it to sleep and wake it up again at the pre-set time. The nP-BLE52 then stores the Nordics SoC’s state variables and waits until the nRF52832 SoC needs to be powered up again. On wake-up, the device uploads the previous state variables, allowing the Nordic SoC to be restored to the same operational state as before the power was cut. The SoC’s start-up is much more rapid than if it was activated from a non-powered mode.

The nP-BLE52 ‘module’ also features a low power MCU which can be set to handle external sensors and actuators when the Nordic chip is switched off. In this state, the module still monitors sensors and buffer readings and can trigger wake-ups if these readings are above predetermined thresholds, while consuming less less than 1uA. The nP-BLE52 also integrates an embedded inertial measurement unit (IMU).

The module’s power management is controlled through a simple API, whereby the user can predetermine the duration of the Nordic SoC’s sleep mode, set the wake-up time and date parameters, and select pins for other on/off triggers.

While Nanopower sought to dramatically improve power consumption when not transmitting, we selected the nRF52832 because it is the best in class for TX/RX efficiency

Tore Irgens Kuhnle, Nanopower
The module offers IoT developers several advantages, either extending battery life and/or reducing the size of the battery required to power the application thereby reducing the end-product footprint. Longer battery life also reduces or eliminates battery swaps and enables the developer to better adjust for remaining useful battery life as the battery discharges. The module is suitable for any battery-powered device which is not required to be constantly active, for example asset tracking, remote monitoring, beacons, and some smart-home applications.

The nRF52832 WL-CSP SoC measures just 3.0 by 3.2mm while offering all the features of the conventionally-packaged chip. The nRF52832 is a powerful multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. It combines an 64MHz, 32-bit Arm® Cortex™ M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM.

The WL-CSP SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation. Nordic’s unique software architecture provides clear separation between the RF protocol software and the developer’s application code, easing product development.

“While Nanopower sought to dramatically improve power consumption when not transmitting, we selected the nRF52832 because it is the best in class for TX/RX efficiency,” says Tore Irgens Kuhnle, CEO, Nanopower. “The WL-CSP packaging was also important because it allowed us to create a small footprint module.

“We know Nordic very well, and in our experience, support has always been fast and helpful.”

An Introduction to Phase-Locked-Loops and RF Oscillators

Courtesy of Pasternack : An Introduction to Phase-Locked-Loops and RF Oscillators

In most RF systems, the production, transmission, and reception of a radio frequency signal is accomplished by way of a transmitter which amplifies and modulates the signal and a receiver system which feeds the signal into the mixer circuits to enable frequency conversion and demodulation. An oscillator is a circuit that generates a repetitive waveform, often an amplifier, with positive feedback. To control the rate of waveform repetition, frequency selection is accomplished by using capacitors and inductors or resistor and capacitor combinations. Phase-Locked-Loops (PLL) are an important class of oscillator which compares the oscillator output with a reference signal and generates a control voltage based upon the phase difference. The control voltage is then used to “lock” in the phase of the output signal.

Basic PLL Components

In other words, a PLL, is an electronic circuit that locks the phase of the output to the input by way of a negative feedback system that synchronizes the voltage controlled oscillator (VCO) output signal to the phase of a reference input signal. A PLL is made of a variable frequency oscillator which generates a periodic signal and a phase detector which compares the phase of that signal with the phase of the input periodic signal, adjusting the oscillator to keep the phases matched by way of a feedback loop. PLLs can be either analog or digital circuits and have a similar structure made up of four basic elements:

• Phase comparator/detector which is a circuit block component that detects and compares  a phase of two signals and generates a voltage based on the phase difference between the two signals; it generates the phase difference between input signals,

• Loop filter that filters phase comparator output and filters out signals from the voltage controlled oscillator (VCO) line and moderates the stability of the PLL by canceling high frequencies and keeping DC components away from the error signal,

• Voltage controlled oscillator (VCO) is the circuit block that generates the output radio frequency signal and is controlled by the error signal from the phase comparator/detector, and

• Feedback path which may include a frequency divider that directs the operational frequency band for the loop from the output signal to the phase detector.

 

PLL Applications

PLLs are used in many radio frequency applications and are necessary components in radio frequency equipment including radio receivers, test equipment, demodulators, and frequency synthesizers. Applications include:

• FM demodulation/AM demodulation

• Indirect frequency synthesizers.

• Signal recovery

• Timing distribution

Types of PLLs

• Analog Phase-Locked Loops (PLL/APLL)

First-Order PLL where the loop Filter frequency response is equal to single pole LP filter

Second-Order PLL has greater flexibility and complexity

Used in communication applications

• Digital Phase-Locked Loops (DPLL/ADPLL)

A DPLL has a digital phase detector and an analog VCO and loop filter

An All-Digital PLL (ADPLL) has all digital components

Used in non-communication applications

• Software Phase-Locked Loops (SPLL/ASPLL)

Mostly used for clock/data recovery

High flexibility such that many PLLs can be software implemented

• Neuronal Phase-Locked Loops (NPLL)

Artificial Neural Network (ANN) is a component in the feedback loop

Used for automatic speech recognition and temporal coding in biomedical simulations of the brain

The benefits of concurrent dual-channel V2X

The benefits of concurrent dual-channel V2X

Courtesy of u-blox : The benefits of concurrent dual-channel V2X

Two eyes see more than one. The same is true for V2X receivers.

Vehicle‑to‑everything, or V2X, is a groundbreaking technology with the potential to dramatically improve road safety, saving thousands of lives each year. Developed and tested over decades, it uses wireless communication to offer vehicles 360 degree awareness of what’s going on around them, beyond line of sight, and with up to one kilometer range.

The only mature and ready‑to‑deploy V2X solution uses the DSRC[1]/IEEE 802.11p wireless standard to let vehicles communicate directly with each other, with road‑side infrastructure, with pedestrians, as well as everything else. Initial benefits include early warnings of traffic incidents for increased safety and smart traffic management for smoother traffic flow. Looking further down the road, V2X will play a key role in enabling autonomous driving.

The UBX‑P3: 100% u‑blox

After two successful generations of u‑blox V2X modules based on third‑party V2X chips, we announced the UBX‑P3 chip, our V2X solution built entirely in‑house, earlier this year. Not only does the UBX‑P3 strengthen the overall DSRC/IEEE 801.22p market offering, the decision to build it from the bottom up gave us freedom to design the chip to meet needs that we observed in the market. One of them is concurrent dual‑channel communication.

If you know anything about the automotive industry, you know that it is heavily regulated to ensure that high quality standards are met. This is as true for V2X as it is for a car’s airbags, its brakes, and its windshield wipers. Ensuring the reception of all safety messages, whether from other vehicles or from nearby infrastructure, is a must for your safety.

The IEEE 1609.4 standard on multi‑channel operation enables such operation with channel switching using a single radio. So why did we implement concurrent dual‑channel communication on our V2X chip?

It’s simple. Two eyes see more than one. The same is true for V2X receivers. On the road, this translates to increased reliability, robustness, and, ultimately, safety.

Understanding DSRC/IEEE 802.11p channels

But before we get into exactly how concurrent dual‑channel V2X communication can be exploited, let’s take a look at some basics of DSRC/IEEE 802.11p V2X communications.

In Europe and the US, the DSRC/IEEE 802.11p spectrum spans 75 MHz in the 5.9 GHz band, and is divided into 7 channels. In both regions, one channel acts as a control channel. Two (Europe), respectively six (US), of the remaining channels are service channels, which may be dedicated to specific communications. South Korea has adopted a similar set up as Europe and the US, while Japan has reserved a single 10 MHz channel centered at 760 MHz for the technology.

Because of their simpler design, single channel V2X solutions are more cost effective than dual‑channel ones. But because they only have a single receiver channel to monitor multiple communication channels, their available bandwidth to monitor safety messages is cut by at least 50%, reducing the safety benefits and the applications that can be deployed. Dual‑channel operation allows to maximizing the V2X safety benefits by tuning one channel to receive safety messages, while the other can be used for other applications.

Key use cases of concurrent dual‑channel communication

Depending on the context, dual‑channel V2X can be configured to continuously follow two communication channels to ensure that no safety messages are lost. Alternatively, one receiver can be set up to constantly stay on the pulse of incoming safety messages, while the second receiver alternates between the control and service channels.

Another interesting use case is truck platooning, in which trucks travel in compact formations to reduce the air drag acting on trailing vehicles, which cut their fuel needs upwards of 13%. V2X is the technology of choice to ensure safety of truck platoons, even at high velocities. Using concurrent dual‑channel communication, one of the available channels can be dedicated to communication between two trucks, while the other channel handles communication with surrounding vehicles.

The UBX‑P3 is the smallest, most power‑efficient V2X chip on the market. Designed to meet the most stringent automotive applications, it is secure and fully compatible with the main global standards, and features an integrated power management unit. There is much more to the UBX‑P3 than concurrent dual‑channel communication. Our on demand V2X webinar looks at other notable highlights, such as single channel diversity, and offers an introduction into V2X, the similarities and differences between DSRC and C‑V2X, and key applications and verticals that the technology will benefit.
