China’s Most Secure Chip Certified Automotive-grade AEC-Q100

Recently, Tongxin Micro, an industry-leading security chip design company, announced that its self-developed THD89 has successfully passed the AEC-Q100 qualification test for automotive applications, indicating that THD89 is currently one of the best automotive chips in China. This is another "heavyweight" certificate obtained by this product following the laurel of the “Chinese chip with the highest security level”. So far, THD89 series have bagged both the financial-grade and automotive-grade security certificates, becoming a benchmark of the automotive security chips.

The automotive industry is moving towards intelligence and network connection. As the chip is a core component to realize the intelligent networking, its security and reliability have received unprecedented attention. Tongxin Micro’s THD89 series have "unique" advantages in information security, and their financial-grade security protection capabilities are second to none. With this "excellent gene", THD89 series are even certified AEC-Q100, adding another advantage for it to march into the automotive electronics industry.

Overcoming Difficulties: Win Ticket to International Automotive IC Module Vendors

Compared with consumer electronics, AEC-Q100 certification is more stringent. As one of the passes for integrated circuit manufacturers to enter the automotive field, AEC-Q100 is formulated and promoted by the Automotive Electronics Association (AEC) to conduct strict quality and reliability confirmation for each chip, especially the standard tests for functionalities and performance of products. AEC-Q100 is widely recognized in the industry.

"In our views, this is more than a simple automotive-grade certification, but also an “important inspection” on our product technology and strength, which is worth our all-out efforts," the company’s project head said, "from the preparation of the project to the product test and to the certificate issuance, it takes nine months for Tongxin Micro to complete the whole process after conducting dozens of reliability tests on tens of thousands of our chip samples. In the end, with the joint efforts of the team, THD89 successfully passed a series of automotive-grade tests including environmental stress, accelerated life simulation test, packaging, chip manufacturing reliability, electrical verification and failure mechanism. Meanwhile, the company has strengthened product quality control, product stress screening and product testing coverage to effectively meet the requirements of the front-loading market for low PPM of automotive-grade chips."

Success only comes through hard work! The ACE-Q100 certificate not only proves Tongxin Micro’s strong capabilities of security chip design but also presents that Chinese automotive-grade security chips are recognized by the global industries and obtain an important ticket to international automotive-grade module factories.

True Power! Comprehensive Indicators Ahead of Global Peers

As a core subsidiary of Guoxin Micro, Tongxin Micro adheres to the mission of "making information and connection more secure" and has been taking the R&D as the focus. The THD89 receiving the AEC-Q100 certification is no exception. Thanks to Tongxin Micro’s nearly two decades of experience in security chip design, THD89 delivers significant breakthroughs in many performance indicators:

This series of products support international and Chinese cryptographic algorithms, and adopt innovative technologies such as memory encryption, bus encryption, electrical environment monitoring, defensive power consumption analysis and fault injection. THD89 is compatible with ISO/IEC 14443 Type A, ISO/IEC 7816, SPI, I²C and GPIO standards. Its overall performance has reached the top level in the industry, as attested by far lower power consumption, the working temperature range  from -40 ℃ to 105 ℃, MSL1, up to 500,000 program/erase cycles and a data retention of 25 years, making it capable of addressing challenging environments and maintain long service life to lay a solid foundation for the IoV system.

Fruitful Results: Promising Market Prospects

More than that, Tongxin Micro makes full use of Unigroup Tsingteng’s capability of micro-system design, combining the hardware with the security OS to develop a powerful set of solutions based on this chip.

Now this solution has been chosen by dozens of automotive electronic enterprises, helping them effectively shorten the migration cycle, accelerating the R&D and the go-to-market time. The market is gaining strong momentum.

With the continuous evolution of technology and the maturity of product capabilities, Tongxin Micro’s security chips and solutions for automobiles are expected to become a necessary part of the IoV applications, and constantly inject drivers into the safety ecosystem of smart vehicles and the development of the global automotive industry. As such, Chinese chip brands will become a leader in the world’s security chip industry.
