Domestic large IoT chip supplier inventory

With the development of the Internet of Things, various technology giants are gearing up and rushing to the beach to prepare for a big battle in this market. Among them, there are many big names such as comets, apples and Lenovo.

Following the computer and the Internet, the world industrial technology revolution has ushered in a new climax - the Internet of Things. The Internet of Everything breeds an unprecedented market, and the realization of this object is inseparable from the brain of the Internet of Things - the chip. Chips, also known as microcircuits, microchips or integrated circuits, mainly refer to silicon wafers containing integrated circuits. Although small in size, they are the core components of computers and other electronic devices.

The IoT chip is not a single product, and the Internet of Things is extremely complex, so it is impossible to cover the Internet of Things, which is being composed of expanding applications and markets, with a single chip. At present, it mainly includes security chips, mobile payment chips, communication RF chips and identification chips, and the demand for IoT chips in these fields is huge.

While enjoying the convenience brought by Internet technology, people also have to face the hidden dangers of information security. The security chip acts as a "safe" and stores the most important cryptographic data in the security chip. According to the security chip, since the password data can only be output and cannot be input, the encryption and decryption operations are completed inside the security chip, and only the result is output to the upper layer, thereby avoiding the chance that the password is cracked. The maximum length of the key length supported by the security chip is 2048 bits. In other words, to unlock the data transmitted by the security chip, the 2048-bit password must be cracked.

Representative manufacturer:

National Technology: The company specializes in R&D and design of integrated circuits and information security cross-cutting areas. It focuses on information security, SoC and radio frequency as the core technology development, covering IC design front-end to back-end full-process technology. The products involve security main control chips. Smart card chip, trusted computing and RCC mobile payment overall solution and other directions and fields.

Huada Electronics: As the world's number one smart card chip maker with market share in China, the products are widely used in financial payment, government public utilities, identification, telecommunications and mobile payment. At present, the security chip of Huada Electronics has been implemented on a large scale, providing a complete solution for security chips for cloud service providers such as Alibaba Cloud and terminal vendors in various industries, and providing information security services between machines and the cloud. This is the successful commercialization of its security products in the field of IoT security after the industrial application of M2M security chips in batch applications in shared bicycles.

In the Internet of Things era, more and more intelligent self-service terminals will appear in our work and life, and the popularity of mobile payment is the biggest driver. At present, the domestic mobile payment solution is mainly a SIM card/SD card product supporting NFC function. Mobile payment chips are mainly used in smart phones, so the demand for mobile payment chips comes mainly from new mobile phones and update iterations.

Datang Microelectronics : As the leading provider of independent information security chips, Datang Microelectronics launched the mobile payment chip module and solution for wearable devices as early as 2015, and is at the forefront of domestic chip manufacturers.

A radio frequency chip refers to an electronic component that converts radio signal communication into a certain radio signal waveform and transmits it through the antenna resonance.

New shoreline: As a leading chip manufacturer in China, New Shoreline has recently launched an RF engine chip, the NR6816, which meets the needs of the future 5G terminal platform. The NR6816 adopts zero-IF architecture, integrates LNA and Pre-PA on-chip, receives and transmits IF filters, supports 3.2-3.8G working frequency band, and supports 20/40/80/100/160/200MHz channel bandwidth on a single chip. Multiple channels can support channel bandwidths up to 800MHz. The NR6816 chip is China's first ultra-wideband radio frequency chip that has been successfully developed and mass-produced. Only ADI in the world has released the same type of chip in the first half of this year. The mass production of the NR6816 chip will greatly enhance China's strength in the global 5G technology research and development competition.

Identity is a solution that relies on the physical characteristics of the human body for authentication. These physical characteristics include the identity of the human body such as fingerprints, sounds, faces, skeletons, retinas, irises, and DNA, as well as personal behavioral characteristics such as signature movements, walking gait, and the strength of the keyboard. In addition to fingerprints that have been widely used, face recognition in the past two years has pushed biometrics to the public. Due to its strong security, identity recognition has developed rapidly in many areas such as financial transactions, information security, and social security.

Huiding Technology : As the world's leading supplier of capacitive touch chips, fingerprint identification chips and solutions, Huiding Technology has built a leading position in the field of human-computer interaction technology for smart mobile terminals including mobile phones, tablets and wearable products. Advantage. It has launched a single-layer multi-touch chip, a push-type fingerprint recognition chip applied to the front of an Android mobile phone, a fingerprint recognition chip supporting a glass cover, a live fingerprint detection technology for mobile terminals, Live Finger DetecTIonTM, and a fingerprint recognition technology in a display screen. Wait.

Tongfang Microelectronics : As a fabless chip design company, focusing on smart cards and related technologies. The company's chips and solutions cover mobile communications, financial payments, identification and information security, and are widely used in telecom SIM cards, financial IC cards, mobile payment cards, USB-Key, social security cards, urban pass cards, and residents. Health card, residence permit and other markets.
