It is another flagship R52+ core automotive MCU that has passed ASIL D product certification after Unigroup Tongxin released the THA6206 chip in July this year, and is highly anticipated by domestic car manufacturers.

Significant performance improvement

Adapt to complex automotive application environments

At the meeting, Yang Bin, deputy general manager of the automotive electronics division of Tsinghua Unigroup , said that as another star product of the THA6 family of high- end control chips from Tsinghua Unigroup, THA6412 continues the advantages of high performance, high reliability and high security, with ultra-large capacity, super peripherals, and ultra-many pins . It uses the Arm Cortex-R5 2+ core, with a main frequency of 400MHz, and uses the V8 streamlined instruction set . It has strong computing power services, a core with lock-step function, and supports virtualization and multi-task isolation; it has the latest version of Bosch GTM 4.1, supports high-precision PWM , and has a built-in hardware RDC module. It can support both soft decoding and hard decoding of resolver decoding methods, which perfectly adapts to the needs of domain control scenarios, especially all-in-one electric drive controllers , engines, chassis domain control, regional control and other applications.

This product is an innovative exploration of the future vehicle architecture. It not only has faster response speed, stronger performance and higher integration, but also has obtained the ASIL D functional safety process and product certification of the ISO 26262 standard. It integrates an efficient HSM module and reaches the highest level of EVITA-Full, with both high functional safety and high information security. It is compatible with the industry's mainstream debuggers , compilers and other tool chains, and can provide customers with a full set of solutions from chip level to system level. Yang Bin said: "With the continuous upgrading of electronic and electrical architecture, our THA family will have more new products on the market."

Enrich product matrix

Accelerate the process of the new four modernizations of automobiles

Under the general trend of electrification, intelligence , networking and sharing, the automotive industry has significantly increased its demand for semiconductor applications, and has also put forward requirements for automotive core chips such as high reliability, high security, high performance and a complete ecosystem.

As a core enterprise of the automotive electronics and smart chip sector of the new Tsinghua Unigroup, Tsinghua Unigroup has always implemented the group's latest development strategy, attached importance to R&D innovation, technological breakthroughs, external links to large industries and ecosystems, and internal links to other companies under the group, and continuously deepened its industrial layout. Entering the era of the "new four modernizations" of the automotive industry, Tsinghua Unigroup has extended the rich experience accumulated in the field of security chips to the field of automotive electronics, and has heavily laid out its automotive control chip product line. In 2021, it launched the first generation of THA6 series chips. This series of products was the first in China to complete a million kilometers of road tests and has been successfully applied in many mainstream car companies. Facing the new E/E domain architecture, Tsinghua Unigroup released the second generation of THA6 series chips in 2024. This series of products is the first domestic Arm Cortex-R52+ core MCU chip that has passed the evaluation of the internationally authoritative certification agency SGS and obtained the ASIL D product Ready certification. It has now been put on the market.

In addition to automotive control chips, Unigroup Tongxin has also created automotive safety chips, power devices and other core products and solutions. The products have been widely used in core automotive fields such as engines & gearboxes, new energy main drives & BMS, wire-controlled chassis, ZCU, ADAS domain control, digital keys, T-BOX, V2X, gateways, etc.

In the future, Tsinghua Tongxin will uphold the philosophy of the new Tsinghua Unigroup of "ambitioning high, going far, creating value", continue to enrich its product matrix with new technologies, new solutions and new applications, improve its business layout based on information security and functional safety, gradually cover peripheral supporting products, and work with industry partners to usher in a new era of smart travel.
