The Internet of Things has always been considered the “next industrial revolution†because it is about to change the way people live, work, play and travel, and even change the interaction between governments and businesses around the world. According to relevant forecasts, by 2020, 34 billion devices will be connected to the Internet, IoT devices will account for 24 billion devices, and the remaining 10 billion devices will be traditional computer devices, while the IoT explosion point is likely to be in smart cars. on.
At the Munich Electronics Show, major manufacturers gathered to bring a wide range of products and solutions for automotive electronics applications. For example, after the transformation, Fujitsu Electronics unveiled the full range of FRAM ferroelectric random access memory products, high-performance graphics processing chip MB86R24 "Triton-C" and Triton full virtual instrument development kit, as well as its agent-rich product line, which is widely used. In the field of smart cars, industrial control and so on. To this end, electronic enthusiasts interviewed Mr. Cai Zhenyu, senior manager of Fujitsu Electronic Components Product Management Department, for the future development trend of new energy vehicle electronics.
Cai Zhenyu, Senior Manager, Fujitsu Electronic Components Product Management Department
Cai Zhenyu said that Fujitsu has transformed from a semiconductor original factory to an electronic component agent. This is the biggest feature of the exhibition. The products exhibited by Fujitsu include FRAM (ferroelectric random access memory), relay (relay), and agent product line. There are many solutions such as Transphorm's GaN, new power supply for new energy sources, Rubycon's cap and Socionext's automotive virtual instrument solutions, and said that the future will be based on the automotive electronics field.
The product line focuses on FRAM and GaN, and gradually moves toward agent distribution.
At present, Fujitsu mainly retains FRAM in its own product line. Cai Zhenyu said that in its product line, FRAM has three unique advantages: First, high-speed reading and writing. It ensures real-time storage and helps system designers solve the problem of sudden power loss data loss in real-time storage data; second, high durability. It can be implemented frequently, recording operation history and system status; third, low power consumption. The main read and write operations consume low power.
On the chip side, Fujitsu's electronic component agent's main chip, Triton, uses ARM dual-core Cortex A9 CPU, integrates independent 2D engine and 3D engine designed for vehicle instrumentation, and provides complete on-board SoC software and hardware development platform, which can shorten the vehicle. The development cycle of image vision related innovation systems.
At the same time, Fujitsu brought Transphorm high-voltage GaN products. Cai Zhenyu pointed out that GaN currently uses Fujitsu's wafers and shares in Fujitsu's Transphorm, but does not participate in research and development. This exhibition of GaN is to let more engineers understand its performance and expand its sales business channels. I found that Transphorm, a leading manufacturer and manufacturer of GaN power converters and modules, chose to integrate with Fujitsu's basic technology and use the 6-inch process of Fujitsu Fukushima Aizu factory to provide a number of key functions for silicon chip manufacturing. This ensures that the GaN power device solution product line enters a reliable mass production chain.
In terms of structure, the GaN HEMT device has a unique structure, in addition to having a faster switching performance than the MOSFET, and because of the increase in operating frequency, the size of its capacitance and resistance is reduced. More importantly, efficiency is not affected while increasing the frequency. Whether it is the gate charge of the forward conduction or Qrr, GaNHEMT has obvious advantages over other products.
Not only that. Cai Zhenyu said that Fujitsu also displayed various passive components, such as Relay relay products, which are characterized by small size, precision and high reliability, and are widely used in the vehicle control and communication industries. There are also a wide variety of Rubycon aluminum electrolytic capacitors for a wide range of applications, including medical devices and flash lamps.
Launched a complete vehicle solution to target the future automotive electronics market
In the development of electric vehicle powertrain system. Cai Zhenyu said that Fujitsu's electronic components focus on the digital power solution - Shindengen TW-78S DC / DC converter and Triton full virtual instrument development kit developed by Triton - C chip.
The new DM-78SDC/DC vehicle-mounted converter: The high-efficiency and copper substrate module enables superior miniaturization of output capacity and modularization at the same cost as previous packages. It uses customizable semiconductors. Optimal design through voltage-resistant FETs and anti-noise chips;
Soxie's high-performance graphics processing chip MB86R24 "Triton-C": ARM dual-core CortexA9 CPU, independent 2D engine (Iris) and 3D engine (OpenGL) designed for vehicle instrumentation, support 3 channels of display output, maximum resolution The rate reaches 1920*720, internal support 6-channel video capture, using eSOL operating system, complete software and hardware development platform can shorten the development cycle.
Finally, Cai Zhenyu emphasized that in the future, Fujitsu will focus on the energy vehicle sector and continue to expand its business. Currently, it also involves industrial, Internet of Things, power management, and gradually move toward electronic device agents. As a Japanese company in China, Fujitsu will take a two-way agency trade in the future, bringing good Japanese products to China, and bringing good products from China to Japan. Through cooperation with online electronic trading platforms, such as Liyuan, etc., we provide users with relatively domestic shortage products and imperfect solutions, and strive to achieve the first place in Japanese electronic device agency.
