u-blox expands its NORA-B2 Bluetooth LE modules series to address all mass market segments

Thu, Feb 06, 2025

u-blox has expanded its portfolio by introducing six new variants of the NORA-B2 Bluetooth Low Energy modules. Now integrating the entire range of Nordic Semiconductor’s next-level nRF54L Series of ultra-low power wireless Systems-on-Chip (SoCs), NORA-B2 offers a versatile solution for mass market segments thanks to its choices of antennas, architectures and chipsets.

The wireless modules combine ultra-lower power consumption and high processing efficiency, consuming up to 50% less current than previous-generation devices while doubling process capacity. They also security features, which makes them ideal for a wide range of IoT applications, such as smart home devices, industrial automation, or healthcare.

The entire NORA-B2 series comprises four variants that differ in memory sizes, design architectures and price levels to match almost any device manufacturer’s requirements.

• NORA-B20 features an ultra-low power nRF54L15 SoC with a 128 MHz Arm Cortex-M33, RISC-V co-processor, and 2.4 GHz multiprotocol radio. It includes 1.5 MB NVM and 256 KB RAM.
• NORA-B21, built on the nRF54L10 SoC, supports multiple wireless protocols (Bluetooth LE, Mesh, Thread, Matter, Zigbee, Amazon Sidewalk) with 1.0 MB NVM and 192 KB RAM.
• NORA-B22 is a cost-effective option with up to 31 GPIOs, 0.5 MB NVM, and 96 KB RAM.
• NORA-B26 is pre-flashed with u-blox u-connectXpress, enabling easy Bluetooth integration without prior expertise.

All NORA-B2 modules are designed for PSA Certified Level 3 security. They incorporate features such as secure boot and updates, tamper detection, and secure firmware over-the-air (FOTA) updates. These security measures ensure that IoT devices remain protected against any potential threats, safeguarding both data and functionality. NORA-B2 modules are also qualified against Bluetooth Core 6.0 that includes Channel Sounding, enabling endless cost-effective possibilities in tracking and locating use cases.

NORA-B2 variants either come with an antenna pin for connecting an external antenna of choice or are designed with a patented PCB antenna providing best-in-class RF performance. All module versions come with global certification allowing device manufacturers to launch their products worldwide with minimal effort.
Samples of NORA-B20 are now available. Early samples of NORA-B21 and NORA-B22 are available for evaluation in limited quantities. The pre-release version of u-connectXpress software for NORA-B26 is also available for early adopters.

Microchip launches the next generation of its low-noise chip-scale atomic clock

Tue, Jan 28, 2025

Microchip has announced its second generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), model SA65-LN, in a lower profile height and designed to operate in a wider temperature range, enabling low phase noise and atomic clock stability in demanding conditions.

Microchip has developed its own Evacuated Miniature Crystal Oscillator (EMXO) technology and integrated it into a CSAC, enabling the model SA65-LN to offer a reduced profile height of less than ½ inch, while maintaining a power consumption of <295 mW. The new design is optimal for aerospace and defense mission-critical applications such as mobile radar, dismounted radios, dismounted IED jamming systems, autonomous sensor networks and unmanned vehicles due to its compact size, low power consumption and high precision. Operating within a wider temperature range of -40°C to +80°C, the new LN-CSAC is designed to maintain its frequency and phase stability in extreme conditions for enhanced reliability.

The LN-CSAC combines the benefits of a crystal oscillator and an atomic clock in a single compact device. The EMXO offers low-phase noise at 10 Hz < -120 dBc/Hz and Allan Deviation (ADEV) stability <1E-11 at a 1-second averaging time. The atomic clock provides initial accuracy of ±0.5 ppb, low frequency drift performance of <0.9 ppb/mo, and maximum temperature-induced errors of < ±0.3ppb. Together, the LN-CSAC can save board space, design time and overall power consumption compared to designs that feature two oscillators.

The crystal signal purity and low-phase noise of LN-CSAC are designed to ensure high-quality signal integrity, which is essential for frequency mixing. The atomic-level accuracy allows for longer intervals between calibrations, which can help extend mission durations and potentially reduce maintenance requirements.
