Ambiq increases security in power processor SoCs

Wed, Mar 16, 2022

Additions to the Apollo4 SoC family by Ambiq are the Apollo4 Plus and Apollo4 Blue Plus with Bluetooth Low Energy connectivity. They have robust security features, said the company, to better protect power-constrained IoT endpoint devices without compromising power efficiency.

The Apollo4 Plus is the fourth generation system processor built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT), enabling new features while reducing devices’ overall system power consumption to extend their battery life. Embedded with Mbytes of MRAM, SRAM, low power processors, solid software stacks and up to 192MHz operating frequency with TurboSPOT, the Apollo4 Plus enables more AI-capable operations, including data ingestion, pre-processing, inference and actuation. Apollo4 has a low power, end-to-end audio subsystem, to run compute complex algorithms needed for precise voice recognition and higher fidelity voice capability needed for voice calls. Its integrated GPU and display controller, coupled with fast and efficient memory access, offer manufacturers the ability to differentiate products with bigger and richer display user interfaces with vivid colours, high-resolution and smooth graphics. Ambiq’s Secure by Design features allow OEMs to secure products from the ground up when implementing SecureSPOT with tools to implement end-to-end security from the start of the design.

“The future of IoT is in the intelligence of things that stay on and connected 24/7,” said Dan Cermak, vice president of Architecture and Product Planning at Ambiq. “The latest product and feature additions to our Apollo4 SoC family demonstrate that battery-operated devices no longer have to compromise performance for power constraints.”

Apollo4 Plus is now in mass production. The enhanced graphics display and greater voice capabilities serve as either an application processor or a coprocessor for battery-powered endpoint devices, said Ambiq. Target applications are smartwatches and smart bands, consumer medical devices, motion and tracking units and smart home devices.

Ambiq specialises in energy-efficient semiconductors for battery-powered IoT endpoint devices. Ambiq has helped leading manufacturers worldwide develop products that can operate for days, months, and sometimes years, on a battery, and even do away with the battery entirely by harvesting energy.

Ambiq’s patented Subthreshold Power Optimized Technology (SPOT) platform has enhanced IoT endpoint devices by enabling a significant increase in compute power at reduced energy levels. The company says its goal is to bring artificial intelligence (AI) where it has never gone before in mobile and portable devices using Ambiq’s low power microcontrollers and SoCs.

u-blox antenna board enables Bluetooth positioning indoors

Wed, Mar 16, 2022

In order to bring reliable indoor positioning devices to market, u-blox offers the ANT-B10 antenna board for Bluetooth direction finding and indoor positioning applications. The board is designed for integration into commercial end-products and enables low power, high precision indoor positioning. It also speeds up evaluation, testing and commercialisation of Bluetooth direction finding and indoor positioning solutions, said u-blox.

Bluetooth indoor positioning uses the angle of arrival (AoA) of a Bluetooth direction finding signal emitted by a mobile tag at several fixed anchor points to calculate the tag’s location in real-time with sub-meter accuracy. The technology exploits Bluetooth’s vast ecosystem and interoperability across platforms and is gaining traction due to its low cost, high accuracy and relative ease of installation and maintenance.

The ANT-B10 is a self-contained Bluetooth low energy antenna board for direction finding and indoor positioning. It has an antenna array comprising eight individual patch antennas, and is built around a u-blox NINA-B411 Bluetooth 5.1 module. After processing incoming RF signals emitted by mobile tracker tags in the module’s radio and angle calculation processor, the antenna board outputs the calculated angle of arrival without requiring any additional processes.

The release also includes the XPLR-AOA-3 explorer kit. This features an application board, which offers developers a quick and easy way to evaluate and test the ANT-B10 antenna board, as well as u-blox’s direction finding algorithm. An off-the-shelf pin header on the application board allows for easy bring-up and testing of ANT-B10 and third-party antenna boards. Connecting the two boards yields a ready-to-use AoA indoor positioning anchor point in seconds, added u-blox.

ANT-B10 and XPLR-AOA-3 complement u-blox’s indoor positioning portfolio which includes the XPLR-AOA-1 and XPLR-AOA-2 kits. Developers can use u-connectLocate, which runs on ANT-B10’s Bluetooth module, to execute the angle calculation algorithms using AT commands.

Common use cases for Bluetooth indoor positioning and direction include tracking assets in industrial settings such as in warehouses as well as people and things in hospitals, retail environments, or museums. Additionally, access control systems deployed in connected buildings can use angle detection to determine which side of a door users are located on.

To determine the angle of arrival of incoming signals for direction finding, the ANT-B10 board concurrently processes them on all eight patch antennas. Implementing multiple RF paths connected to multiple RF switches unnecessarily increases power demand and introduces errors, so the ANT-B10 board uses a single RF switch component from CoreHW that cycles through the eight antennas in microseconds.

The ANT-B10 boards are available today.
