Actually I just want to act

Chapter 1114 Chip Constraints

Shenzhou quickly came up with a full touch screen mobile phone design.

In fact, it is not a full touch screen, because there are three buttons at the bottom of the screen, the main menu button in the middle, and the OK button and the return button next to the main menu button.If someone saw this model in the previous life, they would definitely blurt out: "Isn't this the Nokia 5800!"

Fang Jiming also had a strange look on his face. He didn't expect the design institute to come up with such a model. It seems that the idea of ​​a keyboard phone is still deeply rooted in the hearts of the people.

It is estimated that Nokia also thought so in the previous life. It did not want to abandon its own advantages of keyboards, and felt that it would not be good not to follow up with a full touch screen.So, under the combination of the two, the drum came up with the Nokia 5800 model.In fact, in terms of CPU power, the Nokia 5800 processor is even more powerful than the Apple 4 and A4 processors released two years later, not to mention the Apple 3G released almost at the same time.

It is a pity that Apple's 2G has been deeply rooted in the hearts of the people. The "sci-fi" level of the capacitive screen has already captured a lot of technology trendsetters, but Nokia still uses a combination of resistive screen + stylus, and it is not even a full touch screen. There are still buttons, which is very unsci-fi.

Everything is afraid of comparison, if there is no Apple 2G and Apple 3G, then the Nokia 5800 can be regarded as a good mobile phone.

It is a pity that the Nokia 5800 was born at an untimely time.

"Fang Dong, isn't this design okay?"

Xu Zhuhua was a little nervous. He had been running back and forth between Shencheng and Guancheng for the past few days.In order to get this design proposal, Xu Zhuhua was exhausted.

"A bit thicker."

Fang Jiming was a little helpless. Although this design scheme is feasible, the disadvantage is as obvious as that of the Nokia 5800—it is too thick.Can you imagine a mobile phone that is 1.5 centimeters thick?Yes, that is the Nokia 5800.If you really have no idea, you can look at your fingernails, the part without nails is about 1.5 cm.

As for the Apple 3G, which was in the same period as Nokia, it was only 1.2 centimeters.

Although the same is not thin, they are capacitive screens after all!

Although this design of China is not as good as the Nokia 5800, it still exceeds 1.3 centimeters.Probably it was to leave space for the battery to be removed. Fang Jiming didn’t think the removable battery was bad, but in terms of the texture of the phone, the non-removable battery was indeed more comfortable.In terms of safety performance, non-removable batteries are safer.

"Fang Dong, isn't this thick? Our Shenzhou N3+ is also 1.2cm." Then, Xu Zhuhua took out his mobile phone and said, "This is the mainstream design on the market, and we haven't made it out of the circle. ..."

Fang Jiming thought about it carefully, and it seems that this is indeed the case, because whether it is a flip phone or a slider phone, the thickness is actually not considered thin.Even the thickness of China's first slider phone exceeded 1.5 centimeters, and it went to 2 centimeters.Such a mobile phone is still acceptable to everyone.

"This mobile phone is used to confuse friends and businessmen. It's okay to make it thicker."

Fang Jiming thought for a while and said, "But on a capacitive screen phone, I hope the thickness can be controlled at about 1 cm."

"Fang Dong, is this impossible?"

Xu Zhuhua jumped up in fright, "1 cm?! This is basically impossible!"

Although the industrial design of the new mobile phone has not yet started, neither the system nor the chip has been finalized.What is being promoted now is the system.Judging from Xu Zhuhua's years of experience, this is basically impossible.After all, the chip for this meeting is already big enough, and the motherboard occupies a considerable thickness, not to mention the battery...

"Try your best to keep the function of the removable battery." Fang Jiming was also helpless.To be honest, Fang Jiming really wanted to make a non-removable battery if he wanted to maximize his profits.Because of mobile phones with non-removable batteries, once the battery life is up, many consumers will choose to change their mobile phones.

But if he did this, it would be too much to deceive consumers, and Fang Jiming's conscience was disturbed.

"Um……?"

Xu Zhuhua was taken aback for a moment, and then pondered: "The non-removable battery... can really save the internal space of the phone?"

Fang Jiming said with a smile: "We don't want to be the first to eat crabs. We need to see how consumers accept it. If a friend company releases a mobile phone with a non-removable battery, then we will launch a non-removable battery after everyone accepts it. battery cell phone."

It is estimated that everyone will understand that this mobile phone with a non-removable battery is definitely the mainstream in the future, and the texture of this mobile phone alone is irreplaceable.Holding a thin and light mobile phone in your hand feels different.

"What about other designs?"

Xu Zhuhua actually didn't think this full touch screen phone was good-looking, he thought it had no design at all, like a brick.

When viewed flat, the raised edges make the phone look like a bathtub.

Because of Fang Jiming's request, Shenzhou can only call this phone a "bathtub" phone.Not to mention, it's quite vivid.

Fang Jiming really wanted to find faults, but the design was similar to the Nokia 5800, and there was no fault at all.

"The general design is like this... There is no way, we crossed the river by feeling the stones, and we didn't learn from it." Fang Jiming pretended to say this, "First, build a few engineering machines, test various functions, and try to improve the design. What a small problem. As long as the Tamron 560 tape-out is successful, then mass-produce it.”

Chips these days are mostly 100-nanometer process.

No way, the most high-end process is 90 nanometers, but the cost will go up, and the success rate is very low.

However, there are also many manufacturers that can achieve 90nm manufacturing process, such as Intel, Infineon, Texas Instruments, IBM, and Wanwan's UMC, MK and TSMC.

Therefore, the Tamron 550 chip still uses a 110-nanometer process, while the Tamron 560 chip is designed to use a 100-nanometer chip.

It's not that Fang Jiming doesn't want to get chips with more advanced processes, it's just that his production capacity is limited.

Among other things, Fang Jiming bet on both sides. He placed orders in Wanwan's UMC, MK and TSMC, but he couldn't grab the output of Benteng 4. The demand for them was too high, and the Shenzhou Tenglong 560 chip, At most, it will produce tens of millions of grades, and others have an output of hundreds of millions, which is simply incomparable.

Therefore, mobile phone chips can only be the next best thing.

However, Shenzhou has the design of Tamron 570, and it is also preparing to tape out two chips at one time.

The 90nm process is too critical!

Fang Jiming is very clear that if the chip manufacturing process has not improved in the future, then the 90nm chip process will be used until 2007.Of course, the 90nm process is already very mature, and the main frequency of the chip can go up to 600+MHZ.Among other things, when the first generation of Apple came out, the chip was manufactured using a 90-nanometer process.

When the third-generation Apple 2009GS was released in 3, the 65nm process chip was already used. Well, it will still use the dead star chip.When the Apple 4 came out, the chip was replaced by an A4 processor, using a 45nm process... So far, Apple's chip performance has beaten all competitors...
