GD32A7xx Series

The GD32A71x, GD32A72x, and GD32A74x automotive-grade MCU series feature an ultra-high-performance Arm^® Cortex^®-M7 core architecture, supporting single-core, dual-core, and single-core lockstep configurations. The series operates at two main frequencies of 120 MHz and 160 MHz, delivering up to 763 DMIPS of computing performance. It integrates up to 4 MB on-chip Flash and 512 KB SRAM, and supports dual-bank Flash architecture for seamless OTA updates. With a wide operating voltage range of 2.97 V to 5.5 V and an operating temperature range of –40 °C to +125 °C, the devices are AEC-Q100 Grade 1 qualified and designed for a service life exceeding 15 years, provides a reliable hardware foundation for safe and stable system operation.

To support body control and in-vehicle networking applications, the series integrates a rich set of communication interfaces, including up to 8 CAN FD channels, 12 LIN interfaces, and a 10/100 Mbps Ethernet port with AVB and TSN support. In addition, it provides up to 6 SENT interfaces, meeting the requirements of chassis-related applications and enabling flexible connectivity across a wide range of automotive systems.

In terms of functional safety and security, the GD32A71x/72x series complies with ISO 26262 ASIL B, while the GD32A74x series meets the higher ISO26262 ASIL D requirements. Both series comply with the EVITA-Full security standard and support the SM2, SM3, and SM4 cryptographic algorithms, aligning with ISO/SAE 21434 cybersecurity requirements and enabling secure deployment in global automotive applications.

The GD32A71x, GD32A72x, and GD32A74x portfolio is available in 5 packages and 24 models, providing flexible choices for diverse automotive system requirements.
