The chip uses a 2.97-5.5V wide voltage supply, can operate stably in the operating temperature range of -40℃~+125℃, meets the AEC-Q100 Grade1 standard, and has a working life of more than 15 years, laying a solid hardware foundation for the safe and stable operation of the system.

To meet the needs of diverse body, interconnection and chassis applications, this series of products integrates a wealth of peripheral interfaces, including 6 SENT interfaces; 8 CAN FD, 12 LIN multi-channel high-speed vehicle bus interfaces; and 1x10/100Mbps Ethernet interface supporting AVB and TSN; in addition, it also provides 8 SPI, 1 Quad SPI, 2 I2C and other interfaces.

In terms of safety and reliability, the GD32A71x/GD32A72x series complies with the functional safety ISO 26262 ASIL B standard, and the GD32A74x series complies with the highest level functional safety ISO 26262 ASIL D standard. All products meet the international Evita-full standard information security requirements and support the national encryption algorithm SM2/SM3/SM4, ensuring the security and reliability of data.

The GD32A71x/GD32A72x/GD32A74x product portfolio provides 24 models in 5 packages. It has passed the early user verification and is now officially open for sample and development board applications.

Complete ecosystem software and hardware support to help customers develop conveniently

The GD32A71x/GD32A72x/GD32A74x series of automotive-grade MCUs support the AUTOSAR® automotive open system architecture, and can provide MCU underlying software MCAL. They work closely with many well-known domestic and foreign AUTOSAR basic software suppliers such as Vector, EB, ETAS, Puhua, NeuSAR, Hengrun, GRC, etc., to achieve corresponding adaptation with their BSW or OS. This series of products currently supports mainstream compilers such as GreenHills, Hightec, IAR, Keil, Tasking, and mainstream debuggers such as Trace32, PLS, and I-system, meeting the customer's application requirements for convenient and efficient development and functional safety design. This series of products is equipped with rich documentation and is developed in accordance with the functional safety ISO 26262 ASIL D process, which can provide comprehensive support for customer system functional safety development, including the required functional safety customer documents, such as product safety manuals, configurable FMEDA forms, and safety files required for system certification; as well as functional safety support software, such as CPU STL, safety Lib and MCAL. It is also excellent in information security, supporting leading information security libraries at home and abroad such as Vector, EB, ETAS, and Yishi Intelligence, providing solid protection for vehicle data. In addition, it also complies with ISO/SAE 21434 network information security system certification, effectively helping automakers meet the UN R155/R156 and GB44495 regulatory certification requirements for overseas markets.
