Tongxin Micro's Automotive-Grade MCU Featuring R52+ Cores Receives Highest Functional Safety Certification

Recently, Tongxin Micro's next-generation THA6 series MCU passed the evaluation by SGS, an international authoritative certification body, regarding its functional safety development process and product design. The MCU received two certifications: the ISO 26262 ASIL D functional safety process certification and the ASIL D Ready product certification, making it the first Arm Cortex-R52+ ASIL D MCU in China. This achievement further enhances Tongxin Micro's capability to provide top-class products and services to global customers.

The ongoing development of the automotive "new four modernizations" (electrification, connectivity, intelligence, and shared mobility) has placed higher demands on the performance of automotive chips. Tongxin Micro's next-generation THA6 series MCU is equipped with up to six Arm Cortex-R52+ cores (with lock-step functionality) and can reach a maximum clock speed of 400 MHz. It also features large-capacity embedded non-volatile memory (eNVM), excellent real-time performance, and multi-core capabilities. The MCU meets the high safety requirements for applications in powertrain (such as engine control, electric drive control, and battery management), chassis (such as steering and braking), body, and intelligent driving in both traditional fuel vehicles and new energy vehicles. It also supports new application applications such as domain/zonal control units, providing a reliable foundation for E/E architectures.

As the core company in the automotive electronics and intelligent chip segment of Tsinghua Unigroup, Tongxin Micro has made significant strides in automotive functional safety since entering the field. In 2021, the company launched the first-generation THA6 multi-core domain control chip, which is the first in China to receive ASIL D product certification and to complete 1 million km of road tests in China. This chip has been adopted by leading automotive manufacturers and renowned Tier1 suppliers, earning widespread industry recognition for its outstanding performance.

Looking ahead, Tongxin Micro will continue to leverage its over 20 years of experience in research, development, and mass production. The company will focus on cybersecurity and functional safety, while gradually expanding its product portfolio to include supporting products. Tongxin Micro is committed to providing smarter, more convenient, and more secure chip solutions to address multi-faceted customer requirements and contribute to the high-quality development of the automotive industry.
