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.

Microchip adds ECC20x and SHA10x families of secure authentication ICs to TrustFLEX platform
Secure key provisioning is vital to protect sensitive keys against third-party tampering and malicious attacks. For securing consumer, industrial, data centre and medical applications, secure key storage is essential but the process to develop and document secure key provisioning can be complex and costly. To lower the barrier of entry into secure key provisioning and enable more rapid prototyping, Microchip Technology has added the ECC204, SHA104 and SHA105 CryptoAuthentication ICs to its TrustFLEX portfolio of devices, services and tools.
ECC20x and SHA10x ICs are hardware-based, secure storage devices that are designed to keep secret keys hidden from unauthorised attacks. As part of the TrustFLEX platform, ECC204, SHA104 and SHA105 ICs are preconfigured with defined use cases, customisable cryptographic keys and code examples to streamline the development process.
“Adding the ECC20x and SHA10x pre-configured devices to our TrustFLEX platform will facilitate leveraging Microchip’s secure provisioning services for a broader set of applications,” Nuri Dagdeviren, corporate vice president of Microchip’s secure computing group. “With this platform expansion, Microchip is continuing to strengthen its portfolio, making security authentication ICs more accessible and more specifically optimised for high-volume, cost-sensitive applications.”
ECC20x and SHA10x devices meet Common Criteria Joint Interpretation Library (JIL) High rated secure key storage requirements and have been certified by the NIST Entropy Source Validation (ESV) and Cryptographic Algorithm Validation Program (CAVP) in compliance with the Federal Information Processing Standard (FIPS). The secure IC families are designed to implement trusted authentication to maintain the confidentiality, integrity and authenticity of data and communications in a wide range of systems and applications.
Microchip’s CryptoAuthentication ICs are small, low-power devices that are designed to be compatible with any microprocessors (MPUs) or microcontrollers (MCUs). They provide flexible solutions for securing industrial, medical devices, battery powered equipment and disposable applications. Additionally, the ECC204 is a Wireless Power Consortium (WPC) approved Qi authentication Secure Storage Subsystem (SSS).
ECC20x and SHA10x ICs are supported by Microchip’s Trust Platform Design Suite, which provides code examples and learning materials and enables the secure transfer of credentials to more easily leverage Microchip’s secure key provisioning services. The devices are also supported by the MPLAB X Integrated Development Environment (IDE), product-specific evaluation boards and CryptoAuthLib library support.
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.”
