Ameya360:Nordic Expands PMIC Portfolio

　　Nordic Semiconductor is adding three new product variants to its nPM1100 power management IC product range. Until now, the range has only been available in an ultra-compact 2.1-by-2.1mm chip-scale package (CSP) form factor.　　The first new variant comes in a more mainstream 4-by-4mm QFN component package. CSPs are an absolute requirement for products defined by extreme size constraints. However, when this is not a factor, QFNs allow for easier and cheaper manufacturing as well as simplified design, development, and verification. QFNs also offer greater thermal and vibration robustness compared to CSPs.　　The second and third new nPM1100 variants support higher maximum (termination) battery charging voltages (VTERM) that are required to fully charge certain types of lithium-ion cells commonly used in portable wireless products. These variants will also be offered in either a CSP or QFN package.　　Termination voltage is the maximum voltage a battery should reach during charging. It is used by the battery charger circuit to switch from constant current charging to constant voltage charging and is ultimately used to determine when a battery is fully charged, and so when to stop charging.　　All Nordic nPM1100 variants require no configuration software to operate as all settings are pin configurable.　　“Chip-scale packages are amazing in their miniaturization,” said Geir Kjosavik, Product Director PMIC at Nordic Semiconductor. “In its smallest CSP configuration, the nPM1100 solution only takes up 23mm2 of board space including passive components. However, the product’s ultra-high power management efficiency and ease-of-use bring tremendous value to battery-powered applications where space constraints are not so strict, and so the use of a QFN package is often preferable.”　　Kjosavik said the previous nPM1100’s maximum termination voltage was below that of some increasingly popular lithium-ion batteries used in wearable products. The new nPM1100 variants with higher termination voltage will now maximize the application range and power optimization potential of Nordic’s power management ICs to all portable electronics products.　　The all new nPM1100 product variants are in volume production and available to order now. A new version of the existing evaluation kit (nPM1100 EK) for evaluating the higher termination voltage will be available end of Q1 (nPM1100 EKHV).

Nordic Launches Wi-Fi 6 Companion IC and Dev Kit

　　Nordic Semiconductor has launched the nRF7002 Wi-Fi 6 companion IC and its associated nRF7002 Development Kit (DK). The nRF7002 is the first in Nordic’s Wi-Fi product family and is a low power Wi-Fi 6 companion IC providing seamless dual band (2.4GHz and 5GHz) connectivity. It can be used together with Nordic’s nRF52 and nRF53 Series multiprotocol Systems-on-Chip (SoCs) and the nRF9160 cellular IoT (LTE-M/NB-IoT) System-in-Package (SiP), but can equally be used in conjunction with non-Nordic host devices. The DK makes it easy for developers to get started on nRF7002-based IoT projects.　　Wi-Fi 6 brings significant benefits to IoT applications—such as smart-home products, industrial sensors, asset trackers, and wearables—including power efficiency gains for battery powered Wi-Fi operation, and management of large IoT networks comprising hundreds of devices.　　“The nRF7002 Wi-Fi 6 companion IC is a testament to Nordic Semiconductor’s leadership in low-power wireless technology,” said Svein-Egil Nielsen, CTO/EVP of R&D and Strategy at Nordic. “This highly integrated and flexible solution will empower developers to create new, innovative Wi-Fi 6-enabled products. Supported with the nRF7002 DK and the award-winning nRF Connect SDK, combined with Nordic’s best in class technical support, I believe it has never been easier to develop great Wi-Fi products.”　　“The nRF7002 is designed to work alongside Nordic’s nRF52 and nRF53 Series making it a perfect fit for Matter, a smart-home standard backed by Amazon, Apple, Google, Nordic, Samsung, and hundreds of other companies,” said Finn Boetius, Product Marketing Engineer with Nordic. “The introduction of the IC and the nRF7002 DK now makes it easy for developers to get started on Matter and any other Wi-Fi based applications.” Matter uses Thread and Wi-Fi for data transport, and Bluetooth LE for commissioning.　　The nRF7002 brings low power and secure Wi-Fi to the IoT. The dual-band IC complies with Station (STA), Soft Access Point (AP), and Wi-Fi Direct operation, and meets the IEEE 802.11b, a, g, n (Wi-Fi 4), ac (Wi-Fi 5), and ax (Wi-Fi 6) Wi-Fi standards. The product also offers excellent coexistence with Bluetooth LE, Thread, and Zigbee. The nRF7002 supports Target Wake Time (TWT) a key Wi-Fi 6 power saving feature. Interfacing with a host processor is done via Serial Peripheral Interface (SPI) or Quad SPI (QSPI). The IC offers a single spatial stream, 20 MHz channel bandwidth, 64 QAM (MCS7), OFDMA, up to 86 Mbps PHY throughput, and BSS coloring.　　In addition to its suitability for general IoT applications and Matter, the nRF7002 is the ideal choice for implementing low power SSID-based Wi-Fi locationing when used together with Nordic’s nRF9160 SiP and the company’s nRF Cloud Location Services. SSID-based Wi-Fi locationing supplements GNSS- or cell-based locationing by providing accurate positioning indoors and in places with a high density of Wi-Fi access points.　　The introduction of the nRF7002 is accompanied by the launch of the nRF7002 DK, a development kit for the Wi-Fi 6 companion IC. The DK includes an nRF7002 IC and features an nRF5340 multiprotocol SoC as a host processor for the nRF7002. The nRF5340 embeds a 128 MHz Arm Cortex-M33 application processor and a 64 MHz high efficiency network processor. The DK supports the development of low-power Wi-Fi applications and enables Wi-Fi 6 features like OFDMA, Beamforming, and TWT. The DK includes: Arduino connectors; two programmable buttons; a Wi-Fi dual-band antenna and a Bluetooth LE antenna, and current measurement pins.　　Together with the DK, developing nRF7002-based designs is made simpler by the support for the IC in the nRF Connect SDK, Nordic’s scalable and unified software development kit for building products based on the company’s wireless devices. With the nRF7002 IC, nRF7002 DK, and nRF Connect SDK, developers can quickly and easily add Wi-Fi connectivity to their products, allowing them to connect to the Internet and communicate with other devices over a Wi-Fi network. Example applications for the nRF7002 DK are included with nRF Connect SDK.

Ameya360:Nordic Semiconductor Multi-function PMIC Simplifies System Design

　　Nordic Semiconductor is expanding its power management IC (PMIC) portfolio by releasing a third PMIC in mid-2023. The nPM1300 expands the company’s PMIC offering by adding support for both charging of larger batteries and four regulated power rails.　　Optimized for efficiency, the compact nPM1300 (3.1-by-2.4mm WL-CSP or 5-by-5mm QFN) is digitally configurable through an I2C-compatible Two Wire Interface (TWI). The digital interface provides access to several system management functions that are usually implemented as discrete functions in Bluetooth Low Energy (LE) embedded designs, such as hard reset, battery fuel gauge, system-level watchdog, power loss warning, and recovery from failed boot.　　“Nordic entered the PMIC market because existing power management solutions were not optimized for compact, ultra-low power IoT applications. Available PMICs leave it up to the designer to implement vital functionality using discrete components—functions that naturally belong inside a PMIC and can be implemented at almost no cost,” says Geir Kjosavik, Product Director – PMIC, Nordic Semiconductor. “So, we did just that. Nordic’s customers will be delighted to have access to on-chip functions that enhance product safety and provide additional ways of conserving battery energy.”　　The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52 and nRF53 Series advanced wireless multiprotocol Systems-on-Chip (SoCs). The PMIC’s four regulated power rails and battery charger make it ideal for compact and advanced IoT products based on, for example, an nRF5340 SoC host and multiple peripheral functions such as sensors. Examples include advanced wearables and portable medical applications.　　The nPM1300 PMIC operates from an external power supply of 4V to 5.5V and can operate from a battery voltage down to 2.4V. Two power rails are regulated by separate DC/DC buck converters that are configurable between 1V and 3.3V and up to 200mA maximum current. The other two power rails operate as load switches—switching currents of up to 100mA from external sources—but can also perform as Low Drop Out (LDO) voltage converters when powered directly by the nPM1300. When operating as LDOs, these power rail outputs are configurable between 1V and 3.3V with a maximum output current of 50mA. The unregulated input voltage is also available as an output from the nPM1300.　　The nPM1300 charges single-cell Li-ion, Li-Pol, and LiFePO4 batteries with a linear charging module that supports up to 800mA charge current. The termination voltage is programmable from 3.5V to 4.45V. The battery charger features automatic thermal regulation with programmable maximum chip temperature during charging to enable simple thermal management that can be adapted to any system requirement.　　The nPM1300 brings other new advanced features to Nordic’s PMIC range including: USB port detection with automatic current limits of 100mA or 500mA through standard USB or up to 1.5A through USB-C PD (Power Delivery); dynamic power path management which automatically switches to battery power if a mains power connection is removed; voltage, current and temperature monitoring for accurate fuel gauging; and ultra-low current hibernate mode with a programmable wake-up timer in addition to the other system management features already mentioned. The PMIC also features three LED drivers and five GPIOs that can be re-purposed to direct control lines to time-critical control functions as an alternative to serial commands.　　The nPM1300 is available for limited sampling now, and will be available to order from Nordic’s distributors mid-2023.

Nordic Semi Rolls Integrated Module of IoT

　　After three years in development by teams in Finland and Norway, Nordic Semiconductor introduced a system-in-package (SiP) module for low-power Internet of Things (IoT) applications.　　Nordic's nRF91 integrates an LTE cellular model with narrow-band IoT (NB-IoT) connectivity in a 10x16x1.2mm package. It also incorporates a transceiver, RF front end, dedicated application processor, flash memory, power management and crystal and passive components.　　After announcing last month that lead customers were already sampling the nRF91, Nordic revealed details of the device at an event in Oslo last week. During the event, Nordic also demonstrated the nRF91 operating on the Verizon Wireless Network in the U.S. and on the Telia network in Norway.　　The nRF91 SiP is aimed at secure, low power, cellular connected IoT systems. Jointly developed by Nordic’s specially assembled cellular design team in Finland, and low power team in Norway, the chip was developed from scratch to optimize the power, cost and size savings enabled by the new LTE-M and NB-IoT cellular standards.　　Nordic says the custom SoC combines the benefits of traditional cellular modules — including tele-regulatory and cellular certifications — with ease-of-use and the smallest form factor ever seen in the cellular industry to date. According to the company, the module has up to three times smaller footprint than other solutions on the market and a lower external bill of materials (BoM).　　The module features 23 dBm output power and a -108dBm sensitivity receiver in the 700MHz-2.2GHz range. It also has a throughput of up to 360kbps with LTE-M and 60kbps for NB-IoT.　　Nordic said it worked with Qorvo as a strategic partner for both the RF front end and the SiP development and manufacturing. The nRF91 Series supports global operation with a single SiP variant is a result of the combination of Nordic’s multimode LTE-M / NB-IoT modem, SAW-less transceiver and a custom RF front-end solution from Qorvo.　　With security becoming increasingly a critical consideration in IoT systems, the company says it needed to have a processor with a built-in security platform.　　"Security is the main reason we went for the Arm Cortex-M33 processor and Arm CryptoCell-310 security IP," said Peder Rand, product manager for cellular IoT at Nordic, in an interview with EE Times. "Its architecture brings the TrustZone technology to the embedded space."　　This integration enabled an entire low power cellular IoT application to be implemented on an nRF91 SiP. The built-in host processor features TrustZone for Armv8-M, helping secure application data, firmware, and peripherals using an isolated, trusted execution environment across the CPU and system.　　The SiP also features built-in support for positioning via an integrated assisted GPS (A-GPS) solution that combines cellular and GPS technology to deliver fast and accurate positioning.　　Rand said key target areas initially for the device are in asset tracking, predictive maintenance and healthcare. He said people want to know where their "things" are and in what condition they are in. In healthcare, Nordic is aiming for the professional monitoring of patients’ vital signs in their own homes.　　Rand said that in these applications, small physical size, low power, reliable connectivity and security are essential. The company expects general sampling in the middle of this year and volume production by the end of 2018 with lead customers.　　Nordic says Telia and Verizon are key network partners. Rand said that while Nordic’s business model is to sell electronic components to OEMs and ODMs, these customers need a carrier that enable them to deliver IoT connected products.　　Telia says it is experiencing an unprecedented demand for dedicated IoT connectivity represented by LTE-M and NB-IoT. These technologies enable products and services that wouldn’t otherwise be possible. In Nordic’s press release, it added that access to components has so far been scarce and has hindered large scale commercial launches.
