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

It's just that the technical content and unit price of these chips are much lower than those of mobile phone chips, and they are easy 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.

Don't look at the time difference of just one year, the impact is huge, it is completely one generation ahead.

Originally, Wang Yi was still worried about the Xingyi second generation 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 charging for five minutes and talking for two hours 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 are no technical difficulties, 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 can produce our own router!"

Routers are also the core equipment of smart homes, so Xiaomi and Huawei are all working on them. Wang Yi is unlikely 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.

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, there is 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 support not only 4G band WiFi, but also 5G band WiFi!"

George was a little incredulous: "5G WiFi is the 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 seeing?"

Wang Yi waved his hand: "Don't hesitate, research and develop directly. In the future, 4g+5G dual-band wifi will be the mainstream."

5g WiFi is a standard that was just released on February 18 this year.

In the past, many companies were slow to respond. This year's routers did not support 5g wifi. It will not be until 2013 that first-class dual-band routers supporting 4g wifi + 5g wifi will appear.

By then, single-band routers that only support 4G WiFi will be completely outdated!

This kind of single-band router developed by Xingyi Technology this year will definitely become obsolete as soon as it is launched, and it will be a dead end. 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 4g WiFi, the network speed is stable, and it supports higher-speed transmission. However, once it encounters obstacles, the attenuation will be more serious than the 4G frequency band, and the coverage area will be smaller.

.”

"It can be said that the speed and stability of 5g wifi are many times that of 4g when you are close. But when you are far away and there are many obstacles, such as large flats or villas, 5g wifi is not as good as 4g.

Even 5g wifi can’t cover the whole area, but 4g is OK, so what should we 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 the villa and the entire flat floor. 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, full 5G WiFi coverage in the whole 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 speed is mainly 5M, 10M, and 20M, which is still very slow. A 100M router is enough. But the router is a product that has been used for several years. We also have to consider that the network speed will greatly improve in a few years."

It’s stressful to achieve Gigabit at once, and it’s too radical, so just do 500M. Wait for subsequent upgrades, and then do Gigabit.”

"Okay, I'll implement it now!"

George was young, energetic, and resolute. Wang Yi was 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 only 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.

It’s difficult and it will take half a year.”

"When the GPU, baseband, etc. are successfully developed and packaged together, if everything goes well, they will be tape-out before the end of the year. If the tape-out is successful, trial production and mass production will be possible... But if the tape-out fails, research and development will have to continue.

It’ll have to 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-on-chip integrating GPU and baseband.

You know, the current Qualcomm has not achieved this level.

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 and launch mobile phones equipped with 800, it will be mid-year or even the second half of the year.

Similarly, if the development of Xingyi Technology's 28nm SOC goes smoothly, it will be released at about the same time as Qualcomm. Coupled with mobile phone research and development, it will be launched in the middle of the year, or even in the second half of the year.

There is nothing we can do about this.

Wang Yi looked at Williams: "How confident are you that the film will be successfully released before the end of the year?"

Williams sighed: "Forty percent, I guess. After all, the baseband is too far behind. Previously, VMware's basebands were all 55nm, or plug-in basebands. Now they have to be integrated into an integrated baseband, which is still 28nm."

, it’s even more difficult.”

"Is it only 40%?" Wang Yi had a problem in his mind: "It's okay. The research and development of the flagship SOC will be done steadily. It's too difficult to eat a big fat in one go. If you can be the best before the end of the year, it's okay if you can't. Just keep working hard."

"Thank you, Chairman, for your understanding." Williams breathed a sigh of relief. He was really under great pressure.

Qualcomm has not yet developed a 28nm integrated baseband SOC. It is really difficult for them to develop it.

Wang Yi changed the topic: "But even if the SOC with integrated baseband cannot be completed this year, you will have to come up with a quad-core processor without a baseband and develop a baseband chip that can be plugged in. It will be completed before the end of this year.

The performance is better than NVIDIA tegra 3 and Qualcomm APQ8064 quad-core flagship!"

"That's...good!" Williams responded:

"Quad-core chips without integrated baseband are much simpler than SOCs with integrated baseband. With a large number of R&D engineers from Texas Instruments joining in, there is no big problem. There is also hope for plug-in baseband. Its performance exceeds that of Nvidia and Qualcomm's flagship this year.

question."

Wang Yi nodded: "Very good, in this way, in the first half of next year, we can release the third generation Xphone 3 equipped with a 28nm self-developed chip."

Although Qualcomm's Snapdragon 800 SOC integrates a baseband, it will take the second half of the year, or even the fourth quarter, to be launched due to the time required for mobile phone development.

It can be said that even the Xingyi Xphone 3 plug-in baseband will be invincible in the first half of next year.

As for the launch of the Snapdragon 800 mobile phone from a friend in the second half of next year, will the Xingyi Xphone 3 be at a disadvantage?

No problem either!

It took a year and a half, and by then, Xingyi Technology’s flagship SOC with integrated baseband had been successfully developed and put into mass production.

Wang Yi can launch xphone 3 pro equipped with Xingyi SOC in the second half of next year!

It can still compete with Qualcomm 800.

Without the chip engineers from Texas Instruments, Xingyi Semiconductor will definitely not be able to compete with Qualcomm in a short period of time.

But with the large number of chip engineers from Texas Instruments, Xingyi Semiconductor and Qualcomm have hope to make a comeback.

Without him, the Texas Instruments team's CPU R&D capabilities have always been better than Qualcomm's.
