Among the Ambiq products now available from Mouser are the Ambiq Apollo4 Blue Lite system-on-chip (SoC) and the Ambiq Apollo4 Blue Lite evaluation board. The Apollo4 Blue Lite SoC features a 32-bit Arm® Cortex®-M4 core with a Floating-Point Unit, along with a Bluetooth® Low Energy 5.1 radio with robust RF connectivity. This SoC is ideal for use in battery-powered endpoint devices, including smartwatches, fitness bands, animal trackers, voice-activated remotes and digital health products. The Ambiq Apollo4 Blue Lite evaluation board offers a complete demonstration and development platform for the Apollo4 Blue Lite device.

Mouser also offers the Apollo3 Blue Plus evaluation board and the Apollo3 Blue Plus SoC. The Apollo3 Blue Plus device is based on Ambiq’s Voice-on-SPOT (VoS) platform, making it the perfect microprocessor for enabling always-on voice assistant integration and command. The Apollo3 Blue Plus evaluation board enables quick and easy prototyping of the SoC. The Apollo3 Blue Plus Voice-on-SPOT kit, also available from Mouser, facilitates demos, evaluation, and the development of ultra-low power audio and voice capabilities on the Apollo3 Blue Plus SoC. The kit provides always-on voice capability with options for one or two microphones, signal processing, wake word/command detection, codec, and Bluetooth Low Energy communication.

The Artasie AM1805 evaluation board offers an easy method to measure and evaluate Ambiq’s AM18x5 real-time clocks. The evaluation board includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timer and watchdog functions, and a PC serial interface for communication with a host controller.

Nordic-powered module provides Bluetooth LE audio connectivity

Tue, Dec 19, 2023

Wireless communications company Rayson Technology has released a multiprotocol module based on Nordic Semiconductor’s nRF5340 System-on-Chip (SoC). The SoC is designed for advanced Bluetooth LE audio applications, as well as sophisticated metering, wearable, smart home, industrial, and medical use cases. Measuring just 16.5 by 13.0 by 2.5 mm, the ‘BTM-N340X’ module supports LE Audio and its Low Complexity Communication Codec (LC3), which together enable higher quality, lower power wireless audio streaming compared with existing Classic Bluetooth audio solutions.

The module employs the nRF5340 SoC’s dual Arm Cortex-M33 processors – providing a high performance application processor capable of DSP and Floating Point (FP) alongside a fully programmable, ultra low power network processor. The application core manages the LC3 codec, while the Bluetooth LE protocol is supervised by the network processor.

“The BTM-N340X module has been designed for a wide range of applications, aiming in particular to provide enhanced audio experiences via Bluetooth LE Audio,” says Bob Wu, CTO at Rayson Technology. “It enables one device to stream audio to multiple pairs of wireless headphones, and can facilitate audio broadcasts through public address systems, such as in airports and museums. This module is also compatible with smart speakers and home audio systems.”

The module’s ultra-low power consumption is made possible due to the nRF5340’s power-optimised multiprotocol radio, which offers a TX current of 3.4 mA (0 dBm TX power, 3 V, DC/DC) and RX current of 2.7 mA (3 V, DC/DC). The sleep current is as low as 0.9 µA. Additionally, because the cores can operate independently, developers have the flexibility to optimise performance for power consumption, throughput, and low latency response.

Two flexible antenna options are available for the module—a pre-certified U.F.L Connector and a PCB pin out—depending on the product application. The module is designed to operate within a temperature range of -40 to +85°C.

“The dual processors made the nRF5340 SoC an excellent choice for this module’s LE Audio applications,” says Wu. “The large memory capacity, radio sensitivity, and low power consumption were also major drawcards. In addition to the excellent technical capabilities of the chip, the high level of support from Nordic was a key factor when making our selection.”

Novocomms launches ‘game-changing’ L Band antenna.

Wed, Nov 29, 2023

Novocomms has unveiled NovoSat, a new lightweight dual port product with high performance GNSS capability and offering the full L Band frequency band for other devices.

Developed specifically for use within high density environments, urban canyons and extremely rugged terrains, the new antenna also performs well in poor weather conditions, thanks to its high gain, giving unrivalled performance quality and positional accuracy whilst supporting dual port operation. Designed at Novocomms’ global headquarters in Birmingham, the NovoSat antenna is mechanically rugged, jam resistant and custom manufactured in the UK to maintain product integrity and security.

Ideal for use in satellite phones or global satellite positioning systems, Novocomm’s new antenna weighs just 5g, much lighter than comparable products on the market, due to the innovative use of plastics within the manufacturing process. Traditionally, ceramics have been used in the manufacture of L Band antennas, making them heavier and more expensive than Novocomm’s latest model.

Commenting on the performance of the prototype, Sampson Hu, CEO and founder of Novocomms, said: “Our new NovoSat product really does represent the next generation of L Band antenna, out-performing the competition when it comes to frequency, gain, form factor, efficiency and even price. We’re very excited about the doors that this new product can open for electronic manufacturers working the fields of automotive, mobile devices, AUVs, wearables and also those innovating in the IoT. space.”

The company’s cutting-edge antenna technology is used in a wide range of wireless devices, including laptops, tablets and smartwatches. By offering smaller, more efficient antennas with better performance and lower power consumption, Novocomms is revolutionising the wireless communication industry.

Two data lane ReDriver supports MIPI D-PHY 1.2 protocols

Wed, Nov 15, 2023

A low power, high performance MIPI D-PHY 1.2-compliant signal ReDriver by Diodes, the PI2MEQX2503, regenerates signals transmitted at data rates up to 2.5Gbits per second from cameras to displays. It is suitable for various applications, including laptops, tablets, mobile phones, IoT devices, commercial displays, augmented reality headsets, drones and robots.

It has a dual data lane equaliser and a single clock lane. The PI2MEQX2503 compensates for PCB, connector, cable and switching-related losses. This ReDriver enables optimum electrical performance from a CSI2 source to a DSI sink. It operates at up to 2.5Gbits per second to comply with the MIPI D-PHY 1.2 specification for camera images with increasing numbers of pixels.

The 120mW active-mode power consumption of the PI2MEQX2503 is more power efficient compared to a ReTimer, said Diodes. The low power (5mW), ultra low power (2mW) and shutdown (0.2mW) modes of operation offer further power savings, helping to extend battery life. It also has programmable receiver equalisation, output swing and pre-emphasis to compensate for channel loss with low latency over longer length traces while minimising power consumption.

For added robustness, the PI2MEQX2503 supports a -40 to +85 degrees C operating temperature range for industrial applications. The ReDriver is supplied in a small X1QFN-24 (XEA24) package measuring only 2.0 x 4.0mm.

Diodes is a Standard and Poor’s SmallCap 600 and Russell 3000 Index company, which delivers semiconductor products to companies in the automotive, industrial, computing, consumer electronics and communications markets. It leverages an expanded product portfolio of discrete, analogue and mixed-signal products and packaging technology to meet customers’ needs. The company has 32 sites worldwide, including engineering, testing, manufacturing, and customer service, to serve high volume, high growth markets.
