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.

LUMAWISE Endurance S connector system helps future-proof smart street lighting

Mon, Mar 16, 2020

TE’s LUMAWISE Endurance S connector system, available from Mouser Electronics, features multiple key combinations, with a standardised interface between the receptacle and sealing cap or module base. The versatile system includes several base and dome combinations, with an integrated single gasket that can accommodate and seal both module and luminaire using the same connection interface for 40 mm and 80 mm central management systems. The LUMAWISE Endurance S system is field upgradeable, allowing users to easily upgrade existing luminaires.

The LUMAWISE Endurance S system is Zhaga Book 18 certified, features a 5 A and 250 V contact rating with a 10 kV dielectric withstand voltage (hipot) rating to the mounting surface. The IP66- and IK09-rated receptacle assembly, base and dome combinations provide a sealed electrical interface and robust, impact-resistant packaging solution.

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.
