On January 15, Shanghai SiChang Communication Technology Co., Ltd. held a conference in Beijing officially issued the first self-research wireless routing chip SF16A18 in the mainland, and announced that it will further expand the application field, providing the application of enterprises and institutions and Internet of Things intelligent home. High integration, security and high cost domestic solutions.
In 2014, Yichang Communications was led by Dr. Li Xingren, which was dominated by the second generation Beidou satellite communication chip. The team members have an average of 8 years of industry experience, mainly focusing on design, research and development, sales with the intelligence of the Internet. Home chip and turnkey solution.
SF16A18 uses the most advanced TSM28NM process in the current RF chip, and the CPU part is based on the MIPS instruction set, the dual-core four-processor twelve threads, the highest frequency is 1.2GHz, and the same kind of competition is largely leading the market.
According to Li Xingren, the radio frequency SOC is designed to be dominated by signal processing modules, the baseband and CPU are in an auxiliary bit, and the test of the processor is more focused on the multi-threaded high. Compared to the ARM processor in Android, the MIPS processor is more good at this type of working conditions, and the instruction set authorization cost is much lower than ARM.
Under the premise of ensuring core performance such as CPU, SF16A18 achieves industry-leading high integration, first integrated 2.4GHz and 5GHz dual-band in the same chip, and also supports professional GM GMAC interfaces. The design of the dual-frequency one core makes the auxiliary element on the motherboard to reduce the overall production price of the motherboard.
In addition to the basic communication and processing capabilities, SF16A18 is still under safety. Li Xingren mentioned at the press conference that "network security needs to be solved from the hardware, rather than relying on how many firewalls." The chip integrates multiple encryption engines and communication keys in the underlying, and the hardware supports the national-relief algorithm, through the router firmware The corresponding support and cooperation can support management encryption, allowing device security to increase.
Li Xingren said, in the case of a full combination of hardware and software, even if the router source code is also difficult, it is difficult to get the hardware of the device. And even if the software level is not special adaptation, these underlying algorithms can also enhance the security of the data packets in network transmission.
SF16A18 supports WDS / Mesh extended Wi-Fi wireless coverage, providing flexible WiFi networking, flexible application in various business models, such as operators broadband, wireless router, OED / ODM, and gateways, panels and Audio and other users.
Outside the core product SF16A18 chip, SiCC has also developed a solution for intelligent routers, router mobile applications, trunk panels, controllers, and routing audio, and services that are "Turnkey". Mode, help customers build their own product solutions and rely on the rich experience of supply chain to get more favorable prices.
At the same time, the company has currently planning to continue to sink products, build multimode group universal gateways and router products based on protocols such as ZigBee, Wi-Fi, combined with NB-IOT, connect smart home communications, further layout Internet of Things smart home appliance market.
At present, the chip has realized mass production, mainly in traditional routers, operators broadband entry routers, intelligent gateways, repeater, home server, smart audio, 86 panels. It is expected that in the second half of 2019, Yichang Communications will also provide a second-generation high-performance chip solution, and will further build a module product to create a more complete ecosystem.
