Reborn in 2011, 985 missing from two copies

As a semiconductor giant, Texas Instruments produces many other chips in addition to mobile phone CPU chips.

However, the technical content and unit price of these chips are much lower than those of mobile phone chips, and they are also easier to design.

Williams explained: "Chairman, Texas Instruments' charging chip only supports the current mainstream 5W charging. The Xingyi fast charging chip we developed supports 10W fast charging, which is twice as much! "

Wang Yi was very satisfied: "Very good. After successful tape-out and mass production, the second generation of Xingyi will be equipped with self-developed power chips and fast charging chips! And it will be one year ahead of Qualcomm in releasing fast charging standards!"

"That's totally fine!" Williams said confidently.

The fastest charging efficiency at the moment is only 5V 1A, which is five watts.

Xingyi’s fast charging efficiency of ten watts is twice as fast as the current one.

Wang Yi remembers that in his previous life, Qualcomm released Qualcomm’s first-generation fast charging standard in 2013, which was 10W.

Xingyi Technology can launch it this year.

Even though the time difference is only one year, the impact is huge. It is completely one generation ahead.

Originally, Wang Yi was still worried about the second generation of Xingyi in the second half of the year, which would not have enough highlights.

Nowadays, there are self-developed fast charging chips and battery management chips, especially the fast charging efficiency that is twice as fast, which is definitely the best.

After all, OPPO’s advertisement of five minutes of charging and two hours of talk has attracted a lot of fans.

What’s more, the charging efficiency of Xingyi 2 is twice as fast!

Williams took Wang Yi to George's department:

"Chairman, the smart home SOC chip, power management chip and fast charging chip were all made by George and his people!"

Wang Yi smiled and stretched out his hand: "Very good, George, you have made a great contribution!"

George smiled heartily: "Thank you, Chairman, for trusting me. This is what I should do. We are currently developing WIFI chips and Bluetooth chips. These are essential chips for smart homes. We strive to make breakthroughs as soon as possible."

WiFi chips and Bluetooth chips are much simpler than mobile phone chips.

It can be said that high-end mobile phone chips may not be successful in a year, but simple chips such as WiFi and Bluetooth can be developed several times a year.

These types of chips have been made by George and others at Texas Instruments. There is no technical difficulty, but they are all patented technologies of Texas Instruments.

Therefore, George and his team had to bypass Texas Instruments' patented technology in their research and development and find new solutions to achieve more perfect results.

Wang Yi nodded: "Since we have made the wifi chip and Bluetooth chip, why not develop the router chip as well. Once the research and development is successful, we will be able to produce our own router!"

Routers are also the core equipment of smart homes, so Xiaomi and Huawei are both making them. It was impossible for Wang Yi to give up.

The simplest thing is that if you use other brands of routers, Xingyi Technology’s smart home products have to be set up and linked one by one.

And with Xingyi Technology’s own router, you can connect directly with just one click!

Even if you change to a new Xingyi router, you can still log in to your account with one click and control all smart home devices.

"The router chip is not difficult, no problem at all." George responded decisively.

Wang Yi smiled slightly: "The router I want is not an ordinary router, but a dual-band router. It must not only support 2.4g band wifi, but also support 5g band wifi!"

George was a little incredulous: "5G WiFi is the 802.11ac protocol that was just released a few days ago. Just after it was released, are we going to directly develop dual-band WiFi that supports the 5G band? No more waiting and watching?"

Wang Yi waved his hand: "Don't hesitate, go directly to research and development. In the future, 2.4g+5G dual-band wifi will be the mainstream."

5g WiFi is a standard that was just released on February 2 this year.

In the past, many companies were slow to respond. This year's routers did not support 5g wifi. It was not until 2013 that first-class dual-band routers supporting 2.4g wifi + 5g wifi would appear.

By then, single-band routers that only support 2.4g WiFi will be completely outdated!

This single-band router developed by Xingyi Technology this year will definitely become obsolete as soon as it goes on the market. Wang Yi will not make such a mistake.

Of course, directly All in the dual-band router!

"Okay!" George nodded, still a little confused:

"Chairman, I have a question. The anti-interference ability of 5g WiFi is stronger than that of 2.4g WiFi, the network speed is stable, and it supports higher-speed transmission. But once it encounters obstacles, the attenuation will be more serious than that of the 2.4g frequency band, and the coverage range smaller."

"It can be said that when you are close, the speed and stability of 5g wifi are many times that of 2.4g. But when you are far away and there are many obstacles, such as large flats or villas, 5g wifi is not as good as 2.4g Even 5g wifi can’t cover everything, but 2.4g is okay. What should I do?”

Wang Yi smiled slightly: "This problem is simple. We can develop a function called Mesh networking. Connect several secondary routers to the main router through network cables to achieve full coverage of villas and large flats. This function , we can also launch it together and add it to the smart home solution.”

In the future, Xingyi Technology's smart homes can be purchased by users and DIYed by themselves, or Xingyi Technology can customize a complete set of solutions and install them on site.

Including furniture and appliances, wiring, construction, and full 5G WiFi coverage throughout the house...

Mobile phones are just the beginning of Xingyi Technology, and subsequent smart home appliances for the whole house are the goal.

George kept it in mind: "What M speed can we achieve?"

Wang Yi thought for a while: "The current network speeds are mainly 5M, 10M, and 20M, which are still very slow. A 500M router is enough. But routers are also products that have been used for a few years. We also have to consider how the network speed will greatly increase in a few years." It’s stressful to achieve Gigabit at once, and it’s too radical, so we’ll do it at M and then do Gigabit later.”

"Okay, I'll implement it now!"

George is young, energetic, and resolute. Wang Yi is very satisfied with this.

Of course, these chips must be found by TSMC.

There is no way, the Xingyi wafer fab has not delivered yet, and it will be able to produce some low-end chips next year.

Later, Wang Yi and Williams came to his R&D department:

"Chairman, the research and development of the 28nm flagship SOC is generally going smoothly. Especially the research and development of the CPU part is progressing rapidly, but the SOC also needs to integrate the GPU and baseband. Fortunately, the GPU can directly use the ARM public version architecture, which is not difficult. But the baseband is very difficult. Difficult, it will take half a year.”

"When the GPU, baseband, etc. are successfully developed and packaged together, if everything goes well, they can be tape-out before the end of the year. If the tape-out is successful, trial production and mass production can be carried out... But if the tape-out fails, research and development must continue. It’ll be next year.”

Wang Yi nodded and understood Williams' difficulty.

After all, it is really difficult to develop the most advanced 28nm SOC from the very beginning, which is also the most advanced system-level chip integrating GPU and baseband.

You know, the current Qualcomm has not reached this point.

It wasn't until early next year that Qualcomm released the world's first SOC Snapdragon 800 with integrated baseband, but it was just a release.

By the time mobile phone manufacturers design a mobile phone equipped with 800, it will be mid-year or even the second half of the year when it is released.
