Pervasive Displays (PDi), a world leader in e-paper displays (EPDs), today launches its new range of large-format tri-color displays that render text and images in yellow, as well as black and white. With both 7.4 and 12.2-inch models available, the new EPDs open up fresh opportunities to enrich customer experiences by displaying information in three colors.
E-paper displays are an increasingly popular choice for signage in locations with no mains power, thanks to their ability to operate for months or even years on a single battery. The addition of yellow to the color palette adds greater flexibility, making this display technology a more attractive option in a wider variety of applications.
Signage where information must be dynamic, but only changes infrequently, is an ideal use case for this new range of displays. Office meeting room schedule screens, bus stop real-time departure boards, retail signage and museum information placards (particularly those used in temporary exhibitions or where multiple languages are required) could all be enriched by using tri-color e-paper displays. The yellow e-ink could highlight specific information, such as important facts, changes to bus times or special offers.
Both the 7.4 and 12.2-inch models have state-of-the-art driving waveforms that enable the display of high-quality images at 126 dpi and 103 dpi respectively. And their internal timing controller (iTC) reduces the amount of peripheral circuitry and programming required, resulting in slimline, easy-to-use devices.
Alchin Wang, General Manager, Pervasive Displays, said: “Signage needs to perform a number of key goals, attracting people’s attention and then conveying information as quickly and clearly as possible. The addition of yellow e-ink helps product and service designers on both fronts, thereby supporting better customer experiences.
“This is in addition to the other characteristics of e-paper displays that make them perfect for use in indoor and outdoor signage. These include low energy requirements, wide viewing angles and the use of physical e-ink particles that reflect ambient light, which ensures what’s on the display remains readable even in bright sunlight.”

It can address a wide range of applications in the industrial, automotive, vision, test and measurement, and consumer sectors. The FPGA and all peripherals are powered by the cost-optimized and high-efficiency Enpirion DCDC modules that are well suited for FPGA applications and many other electronic designs. The board comes with two 10/100 Ethernet PHYs to support normal network connectivity as well as industrial Ethernet protocols. Arrow worked with Softing Industrial Automation GmbH to provide an industrial Ethernet implementation for most common real-time protocols, such as PROFINET (RT and IRT), EtherNet/IP and EtherCAT. Also, Modbus TCP is supported. All protocols are integrated using Softing’s modular subsystem architecture with its uniform software interface that allows for easy integration and exchange of the supported protocols.
Data storage, transfer and modifications can be achieved with a variety of memories on the board, including 64 MBit HyperRAM, 256 MBit SDRAM and 64 MBit Flash. To expand the connectivity and adapt other boards with sensors and additional interfaces, there are six PMOD connectors and an Arduino header. A display output is available with a VGA connector and an 8-channel ADC / DAC / GPIO expander gives maximum flexibility on IO signals.
For programming and debugging of the FPGA, the Arrow USB Programmer2 is implemented together with the Intel Quartus Prime FPGA design software. An integrated UART channel in the USB connection allows easy data communication between the application and a PC.
A step-by-step starter guide and a complete FPGA software package is available to address all components directly with the Cyclone 10 LP. A schematic and bill of materials can be used to investigate the details of the board or as a reference for a new FPGA design.
The Arrow Cyclone 10 LP Reference Kit supports all development phases, from the first prototype through to direct use in an end product. A full customization of the board is also possible on request, to achieve an efficient and optimized design for a specific application.

Tyler Ward shared detailed article about not working USB-C chargers with Raspberry Pi 4B. via time4ee.com
The problem is in design of USB-C of Raspberry Pi. HW designers used only one pull-down resistor for both CCx pins.
This solution is not complain with USB-C standard and in case you are using e-marked cable (what is fully complained with USB-C standard), your USB-C charger sets your device, your Raspberry Pi, like “Audio Adaptor Accessory” based on setting of resistors.Due to this wrong design, USB-C chargers (with e-marked label) doesn’t work with your Raspberry Pi. The power is refused. If you buy non e-marked label, there is possibility it will work without problem, because the low-cost cable contains only connection to one CC pin.
Of course, the USB-C power supply made by Raspberry Pi is fully working (and without e-marked label).

X-FAB Silicon Foundries SE, the leading analog/mixed-signal and specialty foundry today announced the availability of new high-voltage primitive devices targeted at the growing market for automotive 48V board net and battery management system (BMS) ICs.
Covering voltages of 70V to 125V, these complementary NMOS/PMOS devices are based on the company’s XT018 BCD-on-SOI (https://www.xfab.com/en/technology/soi/018-um-xt018/) platform with deep trench isolation (DTI) and support for automotive AEC-Q100 Grade 0 products. They deliver competitive on-resistance (Rdson) figures, while still providing robust safe-operating areas for Rdson, Idsat and Vth. A highly effective ESD protection mechanism has been incorporated to ensure long-term operational reliability. In addition, high-voltage N-channel depletion transistors based on the new voltage classes are also available. These will enable simple, area efficient start-up circuitry and voltage regulator implementations to be realized.
48V subsystems are being increasingly adopted by the world’s leading automakers as a means to improve fuel efficiency and reduce CO2 emissions. Mild hybrid cars are the first to utilize 48V-rated components, which will initially focus on a number of core elements, like starter/generators, DC-DC converters and battery management subsystems, as well as other high-current functions, such as water pumps and cooling fans.
At the same time, the fast growing Li-Ion battery markets for electric vehicles and energy storage is moving to taller battery cell stacks which require higher voltages. The XT018 BCD-on-SOI platform now provides an even more flexible voltage offering up to 200V to support the increasing number battery cells that need to be monitored by a single BMS IC.
BCD-on-SOI is superior in many aspects when compared to conventional bulk BCD technologies, making it attractive to designers. Key advantages include virtual latch-up free circuits, strong EMC performance (due to complete isolation with buried oxide/DTI) and simplified handling of below ground transients. Furthermore, through the potential for significant die size reduction along with first-time-right implementation, development periods can be accelerated and lower costs per die can be achieved.
“As the premier high-voltage SOI foundry, X-FAB is now better positioned than ever to support automobile electrification,” states X-FAB CEO Rudi De Winter. “This extension to the popular XT018 platform further strengthens our offering to the hybrid/electric vehicle sector. It means that through this, plus our SiC and galvanic isolation capabilities, we can supply clients with another vital building block that will help accelerate society’s migration to more environmentally friendly transportation.”
X-FAB is the leading analog/mixed-signal and MEMS foundry group manufacturing silicon wafers for automotive, industrial, consumer, medical and other applications. Its customers worldwide benefit from the highest quality standards, manufacturing excellence and innovative solutions by using X-FAB’s modular CMOS and SOI processes in geometries ranging from 1.0 to 0.13 µm, and its special SiC and MEMS long-lifetime processes.
