Network Master Pro MT1040A evaluates 400G networks

Wed, Mar 18, 2020

Anritsu will release the portable MT1040A tester for 400G Networks at the Optical Fiber Communications (OFC) virtual exhibition instead of travelling to San Diego, California, USA.

The Network Master Pro MT1040A is a compact, battery-driven 400G measuring instrument with directly inserted QSFP-DD or OSFP measurement modules.

To date, 400G Ethernet has been used mainly in data centres, but the recent rapid growth in data traffic driven by rollout of 5G commercial services and expected future appearance of self-driving vehicles is seeing deployment of 400G Ethernet at non-data centre locations. The MT1040A supports 400G tests but also 10M~100G Ethernet, OTN, eCPRI/CPRI, SDH/SONET, and Fibre Channel onsite measurements. It can also be combined with an optional OTDR module for fibre line maintenance as well as with a GPS module for remote measurements using GPS. The integrated auto-test functions help operators perform identical tests to obtain quantitative test results, for onsite efficiency.

The Network Master Pro MT1040A is a portable measuring instrument for evaluating the transmission quality of various networks operating at communications speeds from 10Mbits per second to 400Gbits per second. With an evaluation interface supporting SFP/SFP+/SFP28, QSFP+/QSFP28/QSFP-DD, and OSFP optical modules, the MT1040A can be customised easily for any application, says Anritsu.

When combined with the MU100020A, MU100021A, MU100022A, or MU100023A OTDR modules for fibre tests and the high performance GPS Disciplined MU100090A, it measures latency between remote fibre segments.

A full suite of tools is available for easy editing of each test scenario as well as automation tools for one-button operation of complex tests.

Anritsu has provided communications test and measurement equipment solutions for 120 years. The company engages customers as partners to help develop wireless, optical, microwave/RF, and digital solutions for R&D, manufacturing, installation, and maintenance applications, as well as multi-dimensional service assurance solutions for network monitoring and optimisation. Anritsu also provides precision microwave/RF components, optical devices, and high-speed electrical devices for communication products and systems. The company develops advanced solutions for 5G, M2M, IoT, as well as other emerging and legacy wireline and wireless communication markets. Anritsu has offices in over 90 countries worldwide

Development tool focuses on automotive gateway prototyping

Tue, Mar 17, 2020

For prototyping automotive smart gateway and domain controller applications, STMicroelectronics offers the Smart Gateway Platform.

As automotive architectures have evolved to include high throughput in-vehicle networking and high data-rate connectivity to the cloud, the demand for high-performance smart gateway and domain controller electronic control units (ECUs) has also increased, observed ST.

Its modular Smart Gateway Platform (SGP) is built on gigabit Ethernet (GbE) communication between the secure ASIL-B Telemaco3P microprocessor and the ASIL-D SPC58/Chorus microcontroller. This delivers powerful processing capability to handle firewall functionalities, predictive maintenance, over-the-air (OTA) upgrades and high data-rate communication among different ECUs and to the cloud.

The Chorus microcontroller provides real-time, low power, and secure in-vehicle connectivity through its multiple CAN-FD interfaces, explains ST. The Telemaco3P microprocessor delivers dual Arm Cortex A7 processing power with Posix OS support to extend gateway computational capabilities and an embedded Security Module handles OTA updates, firewall and predictive-maintenance functions.

The SGP reference design has in-vehicle network interfaces including multiple Ethernet and CAN ports as well as support for LIN and FlexRay connections. A comprehensive starter package includes hardware design files, hardware/software documentation, software utilities (drivers and flashers) and sample applications.

The SGP also integrates expansion connections to Wi-Fi and LTE modules for full prototyping of use cases requiring cloud-connectivity simulation. The modular architecture provides a framework for scalability in performance, networking, and software, adds ST.

Optiga Connect 5G authenticates mobile consumer devices

Mon, Mar 16, 2020

Infineon has extended its embedded SIM (eSIM) portfolio, adding the Optiga Connect eSIM for mobile consumer devices. It supports all GSMA standards from 3G to 5G and securely authenticates the device to the chosen subscribed carrier network of choice. It has a small imprint, making it suitable for smartphones, tablets and wearable devices (smart watches or fitness trackers).

Based on Infineon’s SLC37 security chip, the new Optiga Connect meets the GSMA’s security requirements and is tested according to Common Criteria CC EAL4+ high. The SLC37 secures sensitive keys and data against fraudulent use. The Optiga Connect eSIM complies with the latest 5G specifications from the GSMA (SIMAlliance Profile Interoperability 2.3 Spec) and the 3GPP. It supports the profiles of major mobile network providers with Remote SIM Provisioning capabilities and offers up to 1.2Mbyte of free user memory for network operator profiles, data and additional applications. The package measures just 2.9 x 2.5 x 0.4mm for the restricted PCB space of many new consumer applications.

ABI Research predicts that global shipments of eSIM enabled smartphones will reach over 225 million in 2020 and it expects a minimum of 500 million eSIM-capable smartphones to ship gloabally in 2024.

The Optiga Connect eSIM consumer chip be available from March 2020.

STM32L4+ microcontrollers bring Cortex-M4 performance to smart devices

Mon, Mar 16, 2020

Two microcontrollers from STMicroelectronics, the STM32L4P5 and STM32L4Q5 microcontrollers bring the performance of the Arm Cortex-M4 core to cost-sensitive and power-conscious smart connected devices, says the company. Target applications include utility meters, industrial and medical sensors, fitness trackers, and smart home products.

The STM32L4+ microcontrollers have memory density down to 512kbyte flash and 320kbyte SRAM. They are available in a choice of package options: 10 x 10mm, 64-pin and 7.0 x 7.0mm, 48-pin versions designed to meet applications limited by size constraints such as wearable form factors.

They have independent power connections for circuitry such as USB and analogue peripherals, independent clock domains, and octal and quad serial peripheral interfaces (SPIs) for external memory expansion. They also feature a 5Msample/s smart ADC that can operate at full speed to minimise acquisition time, or at reduced speed with lower current.

The STM32L4+ microcontrollers exploit ST’s low-power microcontroller technologies and feature seven main low-power modes, enabling designers to creatively manage power consumption and wake-up times to minimise energy demand. The microcontrollers also support FlexPowerControl, which ensures energy-efficient handling of processing loads, as well as batch acquisition mode for energy-efficient data capture while the CPU is stopped.

To preserve system reliability and safety in industrial and medical applications, the STM32L4+ microcontrollers have flash error-correcting code (ECC) support and hardware parity checking for SRAM.

Cyber-protection features include a true random number generator and IP protection through limited access to code stored in internal memory. STM32L4Q5 devices feature additional cryptographic accelerators that support AES, RSA, DH and ECC acceleration.

The STM32 development ecosystem now includes the Nucleo-L4P5ZG Nucleo-144 board and STM32L4P5G-DK Discovery kit, each containing an STM32L4P5 microcontroller.

In the STM32Cube ecosystem, the STM32L4P5 and STM32L4Q5 are supported by the STM32CubeL4 microcontroller package, which contains hardware abstraction layer and low-layer (HAL/LL) peripheral drivers, middleware components and examples projects, and by the STM32CubeMX initialisation-code generator and configurator, which has a power consumption calculator.

ST reports EEMBC benchmark scores of 409 CoreMark and 285 ULPMark-CP for performance and energy efficiency.

Samples are available immediately and full production is ramping up, says ST.
