InGaAs image sensor detects short-wavelength-IR up to 2.55µm

Hamamatsu Photonics has developed an InGaAs area image sensor for hyperspectral cameras capable of detecting short-wavelength-infrared light up to 2.55 µm which is the world’s longest wavelength detectable by this type of area image sensor.

By applying compound opto-semiconductor manufacturing technology fostered in-house over many years, we designed and developed a new area image sensor G14674-0808W made of indium gallium arsenide (InGaAs) capable of detecting short-wavelength-infrared light up to 2.55 µm which is the world’s longest wavelength detectable by this type of area image sensor. Installing this new InGaAs image sensor into hyperspectral cameras for plastic recycling will boost the plastic recycling rate since hyperspectral cameras can screen and sort plastics containing flame-retardant resin to separate them out from other plastics, which has been extremely difficult up till now. They start accepting product orders from domestic and overseas industrial camera manufacturers on July 1, 2019.

This new InGaAs image sensor will be on display at the IMAGE SENSING SHOW 2019 held in Pacifico Yokohama for 3 days from June 12 to June 14, where domestic and overseas manufacturers and experts in image processing devices and sensing technology gather to show off and check out new technology.

X-FAB Silicon Foundries tapes-out open-source RISC-V MCU

X-FAB Silicon Foundries, the leading analog/mixed-signal and specialty foundry, together with crowd-sourcing IC platform partner Efabless Corporation, today announced the successful first-silicon availability of the Efabless RISC-V System on Chip (SoC) reference design. This open-source semiconductor project went from design start to tape-out in less than three months using the Efabless design flow based on open-source tools.  The mixed-signal SoC, called Raven, is based on the community developed ultra-low power PicoRV32 RISC-V core.  Efabless has successfully bench-tested the Raven at 100MHz, and based on simulations the design should be able to operate at up to 150MHz.

Raven is unique in that the open-source top-level design utilizes X-FAB proprietary analog IP and is created with an open-source design flow. This hybrid open-source design brings the power of open innovation and at the same time protecting significant investment in proprietary IP.

Efabless and X-FAB chose to manufacture the Raven on X-FAB’s high-reliability XH018 process. This is a flexible 180nm 6-metal process with a wide variety of options including a low power option, on-chip isolation for high voltages, and high-temperature flash memory. X-FAB’s XH018 process meets automotive quality requirements and is popular in a wide range of automotive, industrial and medical applications.

The semiconductor design is fully functional and Efabless is now engaged with its initial customers on design of derivative offerings. To the Efabless community Raven is available from the Efabless marketplace as a reference design without license fee consequentially advancing the Efabless open innovation model of community design.

“The successful partnership with Efabless demonstrates X-FAB’s continued commitment to open-source semiconductor development”, said Ulrich Bretthauer, Product Marketing Manager at X-FAB. “Nearly 75% of Raven’s die area is covered by X-FAB standard library blocks and macros. Using these proven IP blocks increased the reliability of the Raven while minimizing first-silicon risk.”

According to Mohamed Kassem, Efabless co-founder and CTO, “This project would not have been possible without the support of X-FAB.  They have been an early adopter of the Efabless open-innovation model and this project is the logical extension of our collaboration.”

For companies that want to learn how to get started with open-source IP semiconductor design, X-FAB provides a series of free webinars including “Handling of Complex & Diverse IC Designs Made Easier”, “Design Robustness”, and “IC Lifetime Calculation Made Easy”. Design kits and PDKs for open source IP designs are available. Contact X-FAB for more information.

Tiny TFT Graphics Library for ATtiny84

This is a graphics library for the family of small colour TFT displays based on the ST7735 and ST7789 driver chips. These are really nice displays; bright, colourful, available in a variety of useful sizes, and available at low cost from suppliers like Adafruit, AliExpress, or Banggood. This is a new project by David Johnson-Davies. He writes:

This library allows you to plot points, draw lines, draw filled rectangles, and plot text with an optional scale factor. I’ve included a demo histogram-plotting program that adjusts itself to fit each of the displays I’ve supported.

Unlike most other TFT display libraries this one doesn’t require a memory buffer, allowing it to be run on any processor down to an ATtiny85. The displays require four pins to drive the display, leaving one pin free on an ATtiny85 to interface to another device, such as a temperature sensor. If you need more pins choose a larger chip, such as the ATtiny84; see Using the library with other AVR chips at the end of the article for information about how to convert the code for different chips.

Congatec boards with 8th Gen Intel® Core™ Mobile processor and 10+ years availability

Up to 58% performance boost with extended availability

Congatec, a leading vendor of standardized and customized embedded computer boards and modules, announced today that the brand new embedded versions of the 8th Generation Intel® Core™ Mobile processors (codenamed Whiskey Lake) are now available on COM Express Type 6 Compact modules, 3.5 inch SBCs, and Thin Mini-ITX motherboards. OEM customers benefit from an instant performance boost of up to 58%¹ compared to previous embedded U-Series processors – enabled by 4 instead of 2 cores plus an overall improved microarchitecture. Thanks to features such as optional Intel® Optane™ memory 2 or USB 3.1 Gen2, everyday tasks are even more responsive. The processor cores allow efficient task scheduling and furthermore support the use of the RTS hypervisor software to allow additional optimization of I/O throughput from the input channels to the processor cores.

The new Congatec boards run Linux, Windows 10, or Win 10 IoT Enterprise on the following processors:

  • Core i5-8365UE (4x cores @ 1.6GHz, 6MB cache, 15W)
  • Core i7-8665UE (4x cores @ 1.7GHz, 8MB cache, 15W)
  • Core i3-8145UE (2x cores @ 2.2GHz, 4MB cache, 15W)
  • Celeron 4305UE (2x cores @ 2.0GHz, 2MB cache, 15W)

Designed for harsh and space-constrained environments, the new high-end Intel® Core™ i7, Core™ i5, Core™ i3 and Celeron® embedded processor boards and modules are the first in the industry to offer long-term availability of 10+ years. This brand new embedded x86 design principle premiers at congatec and within the entire embedded board vendor space² with the launch of the new 8th Generation Intel® Core™ Mobile processor boards. Addressing in particular the increased life cycle needs of the transportation and mobility sector, these new boards and modules are also a perfect fit for all other embedded applications – such as medical equipment and industrial controls, embedded edge clients and HMIs – as they enable extended life cycles without additional costs for customers.

“One of our main goals is to simplify the use of embedded computer technology as much as possible for our OEM customers. That’s why we offer our brand new 8th Gen Intel® Core™ Mobile processor based embedded boards and modules now with 10+ and on basis of specific last time buy contract up to 15 years long-term availability right from the start, as 7 years are often insufficient for many high-end embedded computing sectors. Our extended life cycle – which, by the way, comes without additional costs – thus helps OEMs to extend their own product life cycles for an even better ROI,” explains Christian Eder, Director of Marketing at congatec.

In the past, many high-end embedded applications tended towards life cycles shorter than 7 years, as they often required a new performance boost from next generation processors before then. But with increased certification demands in several new embedded application areas such as mobile vehicles, OEMs are similarly keen on longer life cycles today. Extending the life cycles of standard embedded x86 platforms to 10 or even 15 years off the shelf is consequently a major bonus for customers across the entire embedded computing market.

“We are very happy to get our hands on embedded versions of this brand new Intel architecture with 10+ year long-term availability. Longer life cycles are a key requirement in many mobile applications we target in rugged environments, where high speed data streams need to be acquired and logged for 3D object recognition, lidar imaging, and mobile mapping. The same requirement that our end customers expect from our data recorders used for wireless network monitoring and automotive test systems or data loggers for test vehicles which store and analyze high speed data streams from external sensors on solid state drives or hard drives,” explains Thomas Hagios, CEO of MCTX Mobile & Embedded Computers GmbH.

The feature set in detail

The new conga-TC370 COM Express Type 6 modules, the conga-JC370 embedded 3.5 inch SBCs, and the conga-IC370 Thin Mini-ITX motherboards all feature the latest Intel® Core™ i7, Core™ i5, Core™ i3 and Celeron embedded processors with a long-term availability of 15 years. The memory is designed to match the demands of consolidating multi OS applications on a single platform: Two DDR4 SODIMM sockets with up to 2400 MT/s are available for a total of up to 64GB. For the first time, USB 3.1 Gen2 with transfer rates of 10 Gbps is now supported natively, which makes it possible to transfer even uncompressed UHD video from a USB camera or any other vision sensor. The new 3.5 inch SBCs provide this performance via a USB-C connector that also supports 1x DisplayPort++ and power supply for peripheral devices, thereby enabling monitor connection with a single cable for video, touch and power. The COM Express modules support the same feature set on carrier boards. Further interfaces depend on the form factor, but all support a total of 3 independent 60Hz UHD displays with up to 4096×2304 pixels as well as 1x Gigabit Ethernet (1x with TSN support). The new boards and modules offer all this and many more interfaces with an economical 15W TDP that is scalable from 10W (800 MHz) to 25W (up to 4.6 GHz in Turbo Boost mode).

The Conga-TC370, Conga-JC370, and Conga-IC370 are available now, with pricing undisclosed.
