u-blox has announced an expansion to its popular range of R10 products for the fast-growing LTE Cat 1bis cellular connectivity market. Predicted by analyst firm Techno Systems Research Co., Ltd to account for 43.6% of all non-handset cellular devices by 2029, LTE Cat 1bis is expected to be the best-selling cellular technology for the Internet of Things (IoT) for the next four to five years. The new modules strengthen u-blox’s LTE Cat 1bis portfolio, serving both the IoT and users migrating from legacy 2G/3G cellular connectivity.
The new u-blox LEXI-R10 Global provides an ultra-compact 16 x16mm LTE Cat 1bis solution that can be used worldwide in size-constrained IoT applications such as people or pet trackers and wearables. The LEXI-R10 Global is the world’s smallest single-mode LTE Cat 1bis module with indoor location and a US MNO certified core.
Meanwhile, the new SARA-R10 series brings the same capabilities as the LEXI-R10 Global to u-blox’s popular SARA form factor. With 2G and 3G sunsets continuing globally, the SARA-R10 offers product designers using 2G and 3G u-blox SARA modules a straightforward upgrade path to 4G LTE – the most widely available global cellular standard today and for many years to come.
The LEXI-R10 and SARA-R10 offer the option to embed an eSIM, and both modules also include an integrated Wi-Fi Sniffer, providing Indoor localisation via the u-blox CellLocate service based on both a Wi-Fi and cellular networks.
One of the variants is the SARA-R10M10, the world’s smallest LTE Cat 1bis module with embedded Global Navigation Satellite System (GNSS) capable of concurrent communication and tracking. It is the ideal solution for asset tracking and telematics applications that demand continuous connectivity as well as indoor and outdoor positioning anywhere in the world, thanks to the blend of GNSS, Wi-Fi scan and global LTE coverage. This module is also 50% smaller than u-blox’s previous LTE Cat 1bis combo, the LENA-R8M10.
The new u-blox R10 modules give product designers a 4G cellular connectivity solution for IoT applications that require medium data rates, worldwide portability, ultra-low power consumption and compact sizes.

Taiwan Semi’s new ESD protection devices are optimised for high-density electronics
Taiwan Semiconductor has introduced a new series of new ultra-small ESD protection devices optimised for wearables and other high-density electronic products. All DFN0603-packaged models in the 3.3V and 5.0V TESDx Series exceed the 8kV IEC61000-4-2 20kV contact discharge standard as well as IEC6100-4-5 4A peak pulse current, with margin. TESDx Series devices utilise Taiwan Semiconductor’s proprietary clamping cells to prevent overvoltage damage from ESD and lightning on control, power and data lines. Additionally, their industry’s lowest capacitance allows for full USB 3.0 data rates without compromise.
Applications for the new 3.3V/5.0V ESD protection series include wearable products, portable medical and test and measurement instrumentation and IoT and IIOT devices. Other applications include consumer electronics, computing, networking, peripherals, USB3.X ports and any application where ESD protection is needed — and where size is a top-of-mind concern.
The TESDx Series offers three models to choose from:
• TESDH3V3B03P1Q0 3.3V/40W 0.2pF
• TESDL3V3B23P1Q0 3.3V/70W 17pF
• TESDH5V0B03P1Q0 5.0/100W 0.2pF
“For wearables and other high-density electronic products, the devices used for ESD protection should be as small and thin as possible, so our new DFN0603-packaged devices are an ideal choice,” said Sam Wang, vice president, TSC Products. “The 3.3- and 5.0-volt models in the series provide full-compliance electrostatic discharge and electronic fast-transient protection, with margin. When protecting high-speed data signals, they also offer extremely low capacitance to ensure that the signal integrity in the application remains within spec and uncompromised.”

ROHM develops the industry’s smallest CMOS Op Amp for smartphones and IoT devices
ROHM has developed an ultra-compact 1.8V – 5V, rail-to-rail CMOS operational amplifier (op amp) – the TLR377GYZ. It is optimised for amplifying signals from sensors such as temperature, pressure, flow rate, used in smartphones, small IoT devices, and similar applications.
The size of smartphones and IoT devices continues to decrease – requiring smaller components. To accurately amplify small signals as needed in high precision sensing, op amps must improve low input offset voltage and noise performance while continuing to shrink the form factor.
The TLR377GYZ succeeds in balancing miniaturisation with high accuracy (which has been difficult to achieve with conventional op amps) by further evolving proprietary circuit design, process, and packaging technologies cultivated over many years.
Op amps’ input offset voltage and noise generation degrade amplification accuracy and can be suppressed by increasing the size of the built-in transistors – but at the expense of miniaturisation. In response, ROHM developed proprietary circuits which achieve a maximum offset voltage as low as 1mV without increasing the size of the transistors. In addition, proprietary process technology greatly reduces flicker noise, while ultra-low noise is achieved with an input equivalent noise voltage density of 12nV/√Hz by optimising the resistive components at the element level. Furthermore, the new product adopts a WLCSP (Wafer Level Chip Scale Package) with a ball pitch of just 0.3mm utilising original packaging technology. This reduces size by approximately 69% compared to conventional products and 46% over existing compact products.
New version of the Cohesity Data Cloud 7.2 brings faster and more efficient data protection
Cohesity, has announced the new version 7.2 of its flagship platform Cohesity Data Cloud. This unified cloud data management platform for securing, managing, and extracting value from data gets a series of enhancements around speed, security, scale, and simplicity to help organisations improving cyber resilience for their entire data estate.
As the number and quality of cyberattacks in Europe continues to increase, companies must meet stricter legal requirements such as DORA and NIS2 for greater cyber resilience. The new version of the Cohesity Data Cloud has been expanded with numerous functions to enable companies to master this balancing act and implement regulatory requirements despite unpredictable threat vectors for all their data, regardless of where it is located.
The most important innovations in the new version, available as self-managed software and SaaS, include better security thanks to OAuth 2.0 support, stronger control and recovery of Kubernetes workloads, and more flexibility and efficiency when deploying in the three major cloud platforms Amazon Web Services, Azure, and Google.
Cohesity’s platform has long embraced “secure by design” principles. Cohesity is elevating this platform security with support for OAuth 2.0 authorisation in the Cluster APIs. For users that automate workflows with Cluster APIs, this offers three main benefits:
• Enhanced security: Reduce the risk of credential theft by using access tokens instead of sharing passwords
• Scalable integration: Simplify connecting automation scripts securely without compromising user data
• Improved session control: Empower admins and security teams to centrally grant and revoke access permissions to their data from their Identity Provider, enhancing trust and compliance
Auth 2.0 with OpenID Connect gives you passwordless authenticated access to Cohesity REST APIs. If organisations use an external identity management system like ADFS, they’ll want to use the feature to configure Single Sign-On (SSO) and add SSO user groups to their Cohesity clusters. By centralising access controls and permissions management, customers can enhance trust and ensure compliance across the board.
Cohesity Data Cloud 7.2 includes effective capabilities for Kubernetes deployments, offering customers more efficiency and control over their backup and recovery workflows.
• Dedicated VLAN support for Kubernetes: Customers can now configure separate VLANs for efficient data traffic management. Create dedicated networks to route backup and recovery traffic seamlessly within the Kubernetes cluster. This feature improves performance and helps you meet service level agreements (SLA) for Kubernetes deployments.
• Granular PVC backup and recovery offer greater customisation: Kubernetes administrators can toggle the inclusion of Persistent Volume Claims (PVCs) within namespaces during the backup and restore processes. Use this feature to strategically select PVCs for backup, improving the effectiveness of your data protection strategy.
For organisations shifting to the cloud for enhanced flexibility, accessibility, and scalability, Cohesity Cloud Edition builds upon existing functionality, offering a robust solution for securing and managing data in the public cloud. It grants customers greater control over deployment while entrusting the underlying infrastructure management to cloud providers. The new version of Cohesity Cloud Edition seamlessly integrates with the control plane, so organisations can centrally administer all your Cohesity clusters no matter where they run. It is now generally available on three major cloud platforms: Amazon Web Services, Azure, and Google.
With this latest release, customers can achieve a lower TCO and better performance offering multiple configurations, up to 200 TByte per node, that simplify operations and reduce overall storage costs. Compared to prior versions of the cloud edition, the new version can help organisations realise over 100% ingest throughput, require up to 50% fewer nodes per cluster, and reduce costs by up to 66% per terabyte.
