  【Lansheng Technology Information】On September 1, 2023,  Samsung  announced that it has developed its largest-capacity 32Gb DDR5 DRAM (DDR5 DRAM: fifth-generation double data rate synchronous dynamic random access memory) using 12-nanometer (nm) process technology. This is another achievement following Samsung's mass production of 12nm-class 16Gb DDR5 DRAM in May 2023, which solidifies Samsung's position in the field of developing next-generation DRAM memory technology and opens a new chapter in the era of large-capacity memory . "Based on  Samsung's  latest 12nm-class 32Gb memory, we can develop a solution to achieve 1TB memory modules, which will help meet the growing demand for large-capacity DRAM memory in the era of artificial intelligence and big data." SangJoon Hwang, executive vice president of the memory development group of Samsung Electronics Memory Division, said, "We will continue to develop memory solutions through differentiated process and de...

  【Lansheng Technology Information】May 31, 2023 —  Vishay Intertechnology  announced that it has launched a new thick film power resistor ISOA that has passed AEC-Q200 certification, adopts a small SOT-227 package, and can be directly mounted on a heat sink. . Vishay MCB has high pulse handling capability, power dissipation up to 120 W at 85 C bottom case temperature, optional NTC thermistor for internal temperature monitoring, pre-coated phase change thermal interface material (PC-TIM) to improve the paste Install efficiency. The recently released device uses an aluminum substrate instead of a metal sheet, which can be used as a pre-charge, discharge, active discharge or snubber resistor, reducing costs for automotive, industrial, avionics, defense and space (AMS) applications. ISOA can choose to integrate AEC-Q200 certified and temperature cycle tested NTC thermistors in the resistor package, which simplifies design and saves board space. At the same time, optional PC-T...

  【Lansheng Technology Information】 ROHM , a world-renowned semiconductor manufacturer, has launched two new high-speed thermal printheads "TE2004-QP1W00A (203dpi)" and "TE3004-TP1W00A (300dpi)", which are very suitable for logistics and inventory Barcode label printers used to print labels in areas such as management. In recent years, the e-commerce (EC) market has been booming, and consumers' needs have become more and more diverse, which has led to an increasing demand for logistics labels and inventory management labels. However, with the previous thermal print head technology, 250mm/sec to 300mm/sec is already the limit of printing speed. Against this backdrop, ROHM has developed highly reliable high-speed thermal printheads using new structures and technologies, achieving print speeds, print quality, and durability that surpassed previous limits. Compared with the previous products, the new products have been greatly improved in terms of circuit board mate...

  【Lansheng Technology Information】April 25, 2023, STLINK-V3PWR is a new in-circuit debug programmer from  STMicroelectronics , which can accurately measure the application running on any STM32 microcontroller (MCU) power consumption. The product's wide dynamic range can handle power-sensitive developments such as IoT and wireless applications, and can measure current values from nanoamps to 500mA with a measurement accuracy of ±0.5%. In addition, the product can provide up to 2A of current to the target system with a single USB cable, and developers do not need to connect a separate power supply to power the board. STMicroelectronics'  STM32CubeMonitor-Power graphics tool directly supports STLINK-V3PWR, which can display the power demand of the application in real time and analyze the impact of design changes on power consumption in order to improve energy efficiency. Additionally, the product is supported by Arm® Keil® development tools and the IAR integrated developmen...

  【Lansheng Technology Information】June 1, 2023 -  NXP Semiconductors  officially released the i.MX 91 application processor series. Building on NXP's more than two decades of leadership in developing multi-market application processors, the i.MX 91 family offers an optimized combination of security, features, and power efficiency for next-generation Linux®-based IoT and industrial application needs. Newly released protocols change the direction of new product categories in the IoT and industrial markets, such as Matter, the interoperable secure connectivity standard for the smart home of the future, or the ISO 15118-20 standard for electric vehicle chargers. Such new products are usually based on Linux, because Linux can provide developers with the scalability and programming convenience they need to promote application development and extend product life.  NXP's  i.MX 91 family enables developers to quickly create new Linux-based edge devices such as home cont...

  【Lansheng Technology Information】Recently, at the 2023 SID Display Week event held in the United States,  Samsung  demonstrated a brand new screen panel called Sensor OLED, which is the world's first OLED panel with built-in fingerprint sensor and heart rate sensor. There is no significant difference in display performance between the Sensor OLED panel and the traditional OLED panel, but the Sensor OLED panel has a built-in light-sensing OPD (organic photodiode), which makes it no longer necessary to separate the screen under the screen during the production process of mobile phones and other products. Installing the fingerprint sensor not only reduces the space occupation, but also reduces the cost.  Samsung  says the technology can significantly reduce the complexity of a phone or tablet by integrating biometric and health-tracking sensors. According to  Samsung  Display, this light-sensing technology is built into each pixel of the new OLED panel,...
