Avnet Embedded is introducing a 7in WVGA TFT-LCD module for industrial applications such as construction, agricultural vehicles and factory automation. The module, manufactured by Mitsubishi Electric, will be available in sample quantities at the end of February. 

Resisting vibration as high as 6.8G – said to be seven times greater than that of conventional modules – the display operates in temperatures ranging from -40 to 85°C and has a brightness of 1500cd/m2. The company says the module has a contrast ratio of 800:1, enhancing visibility in bright environments.

ADLINK Technology has launched its first COM Express Compact Size Type 6 module. The cExpress-BL, based on 5th generation Intel Core processors, comes with support for up to 16Gbyte of dual channel DDR3L memory and features improved graphics and processing performance.

Said by ADLINK to be suitable for use in fanless edge devices, the cExpress-BL is likely to be used in space constrained applications, including digital signage and machine vision.

The board features Intel HD Graphics 5500 and 6000 integrated in the CPU and provides two DDI channels (with up to 4K resolution) and one LVDS channel supporting three independent displays. This allows it to drive multiple HD screens without the need for a separate graphics card. In addition, an optional Embedded DisplayPort is available to support next generation displays.

High bandwidth I/O includes four PCIe x1 lanes or one PCIe x 4, four SATA ports supporting 6Gbit/s, two USB 3.0 and six USB 2.0 for peripheral devices and data transfer.

The cExpress-BL is equipped with ADLINK's Smart Embedded Management Agent (SEMA) to provide access to detailed system activities at the device level, including temperature, voltage, power consumption and other key information.

Designers looking to work with STMicroelectronics' STM32 microcontrollers can now do so using the company's STMCube software development platform. According to the company, it has now completed roll out of the package to all members of the STM32 MCU family currently in production. 

Designers looking to work with STMicroelectronics' STM32 microcontrollers can now do so using the company's STMCube software development platform. According to the company, it has now completed roll out of the package to all members of the STM32 MCU family currently in production.

STM32Cube allows designers to start working with any STM32 device, simplifying porting of code from one product series to another. It comprises the STM32CubeMX graphical configurator and initialisation C-code generator, which provides wizards that help configure the pin out, clock tree and peripherals. It also helps engineers to meet power consumption constraints.

After configuration, the tool not only generates C initialisation code, it can also download the corresponding embedded software automatically. ST says this saves time and helps to overcome resource conflicts.

STM32CubeMX is not dedicated to a proprietary development environment and can be used with such IDEs such as ARM/Keil MDK-ARM, IAR's EWARM and those based on GCC.

STM32Cube also provides embedded software packages for members of the STM32 series. The latest package to be added supports STM32F1 devices and any future STM32 families will receive STM32Cube support upon introduction.

Each embedded software package comprises a hardware abstraction layer with fully portable APIs, checked using Grammatech CodeSonar. Closely integrated middleware is said to eliminate the task of assessing dependencies between individual software components. In addition, a built-in update mechanism relieves the burden of checking software status.

Middleware includes: the LwIP open source TCP/IP stack; FreeRTOS with the CMSIS-RTOS wrapper; an open source FatFS file system; and ST's USB Host and Device library, touch sensing library and STemWin graphics stack.

Infineon Technologies has extended its OptiMOS 5 portfolio with the addition of 80V and 100V variants.

Optimised for applications requiring high switching frequencies, OptiMOS 5 MOSFETs are said to offer significant reductions in on-state resistance (RDS(on)) compared to the previous generation. According to Infineon, this can be up to 45% less for the 80V version and up to 24% less for the 100V part. Lower resistance means there is less need to parallel parts, hence reduced material cost.

Meanwhile, the OptiMOS 5 80V variant offers 38% reduction in output charge and the OptiMOS 5 100V variant a 25% reduction. Less output charge, the company adds, means reduced switching losses and lower voltage overshoot in hard switching topologies and synchronous rectification.

The additions to the OptiMOS 5 family are available in seven packages: SuperSO8; S308; TO-Leadless; TO-220; TO-220 FullPAK; D²PAK; and D²PAK 7Pin. RDS(on) ranges from 1 to 4 mO, 4 to 8 mO and 8 to 12 mO for the 80V device and from 1 to 4 mO, 4 to 8 mO and 8 to 10 mO for the 100V variant.
