Chapter 232

Compared with the electronic compass that can be delivered directly, Saito benwu cares about two other things: audio chip and gravity accelerometer.

Although it is a giant in Japan's semiconductor industry, Asahi's audio chip does not occupy the world because of the existence of a stronger Italian French semiconductor company.

Even if Saito benwu believes that the audio chips produced by his company have reached the world-class level, the sales volume of Asahi Kasei's audio chips has not been very good because of the long-term monopoly of Italy France semiconductor.

There are also gravity accelerometers. Apple once asked Asahi Huacheng, but Asahi Huacheng finally lost. They don't know who they lost to.

The so-called gravity accelerometer is a small metal kit built into the machine. Because there are three axes to maintain balance, this tora type metal accelerometer will remain horizontal and vertical at any time.

The gravity accelerometer can automatically sense the change of mechanical orientation, so as to adjust and switch the function of corresponding change.

Saito benwu knows that at present, Apple has used the gravity accelerometer on the mobile phone they developed. It is said that it can automatically correct the screen according to the handheld direction. The use of this novel smart phone makes Saito benwu very interested. Although the effect of previous research and development was not very good, it has made great progress.

Saito benwu even believed that if he had another competition, his gravity accelerator would never lose to others.

Now it seems that there is always a way out of heaven.

Although Apple's orders are gone, the materials and design drawings brought by this Chinese teenager are highly professional and very in line with the characteristics of Asahi Huacheng microelectronics. Naturally, Saito benwu is interested.

The Japanese are much more careful than the Americans. Therefore, even though Saito benwu has been moved, he politely asked Xiao Qi to leave the design drawings and schemes for discussion with the researchers.

Of course, the necessary confidentiality agreement was signed in the presence of two staff members of Citibank. Xiao Qi was not very confident about the Japanese's reputation for the Chinese people.

Saito benwu should consider.

Bilda's DRAM memory chip and Toshiba's NAND flash memory chip don't pay so much attention. Because the technology is mature and won't be modified, they let Xiao Qi purchase directly.

The difference between the two is actually very simple. DRAM memory chip has fast real-time storage speed, but the data will disappear after power failure. This memory chip is usually used to play games and use working software; NAND flash memory chip is stored for a long time and will not disappear after power failure. It is usually used on mobile phone memory card.

To put it bluntly, DRAM memory chip is equivalent to the memory of ordinary computer, and NAND flash memory chip is equivalent to the hard disk of ordinary computer.

Memory and hard disk.

It's that simple.

As a complete tablet computer, real-time storage and power-off storage can not be lacked, so Xiao Qi is equipped with both, without saving.

Because of the five-year contract and the large purchase of 30 million sets per year, and because the spring of the two memory chips has not yet come, the price of each DRAM memory chip is $18, the price of each 16GB NAND flash chip is $28, and the price of each 32GB NAND flash chip is $55.

Hoya, which is controlled by the Suzuki family, an old Japanese optical company that has helped China build the optical glass industry, also has its own set of ambient light sensors.

In fact, this ambient light sensor with the same function as the gravity accelerometer is used on many high-end touch screens, but businessmen in Baodao are used to saving. CHENHONG optoelectronics does not use the electronic map sent to Xiao Qi's mailbox because it will greatly increase the cost of the touch screen.

Xiao Qi couldn't hear it. He had to add this item before he came to Japan. He spent a deposit of $10 million and set a five-year contract at the price of $1.50 each. He got 30 million ambient light sensors every year.

Then, at the first time, Xiao Qi sent Heuer optical ambient light sensor to CHENHONG photoelectric, so that they should install integration on the touch screen anyway to achieve the best touch effect.

Three days after the initial meeting, Saito benwu has agreed to Xiao Qi's contract. The two sides signed the supply contract of gravity accelerometer, electronic compass and audio chip in the presence of Citibank.

The price of gravity accelerometer is US $1.8, the price of electronic compass is US $1.50, and the price of audio chip is US $1.2. It is also 30 million sets each year. The contract signed is still five years.

As long as Xiao Qi completes his motherboard CPU and GPU, Asahi Huacheng Microelectronics will carry out all kinds of debugging according to the motherboard and make the products most suitable for the motherboard chip of tablet computer.

In today's mobile phone industry, the 5mm camera component is not very slim, but the iPad is relatively large. Therefore, the size of the camera can be more tolerant than that of the mobile phone.

The one who received this 5mm size camera was Ricoh Co., Ltd. of Japan.

Although Ricoh is not as professional as canon and Nikon, it is more professional than Sony and Olympus.

Ricoh's technology is enough for the lightweight camera of mobile phones, and most importantly, the camera it supplies is much cheaper and of better quality than Sony's gorgeous appearance.

Ricoh has been thrown away by Canon and Nikon in professional cameras over the years. On the card machine, it has also been slapped by Sony and Olympus. It is almost ready to give up the development of this piece. How can a life-saving living Bodhisattva like Xiao Qi not be ecstatic and honestly give a reserve price?

For a 3-megapixel camera component, each tablet needs one at the front and back. Ricoh's price of $2.30 for each component will supply 60 million sets every year for five years, and the camera pixels must increase by at least 1 million every year. This price is very reasonable.

Xiao Qi vaguely remembers that the cost price of the 700000 pixel camera on the iPad 2 seems to have reached two dollars a piece. Later, everyone was criticized and satirized. In a rage, Qiao gang leader directly dismissed the vice president in charge of procurement.

The pixel won't get better until the iPad 3, but the price is about $2.50.

Although the price of future mobile phones and tablet cameras will be reduced to about $1 with the development of technology, the price of high-end cameras has been relatively strong, still floating around $2（ It's not finished yet.
