Product Description：

The GD32A744AZT3TB is a member of GigaDevice's flagship GD32A744 series of automotive microcontrollers. It is built around a high-performance Arm® Cortex®-M7 core operating at up to 600MHz, enhanced with DSP extensions and AI acceleration capabilities for demanding real-time and edge-intelligence tasks. Designed to meet stringent automotive reliability standards (AEC-Q100 Grade 2) and support functional safety development (ISO 26262), it integrates critical features such as a Hardware Security Module (HSM), high-speed communication interfaces (including TSN-ready Gigabit Ethernet and multiple CAN FD), and substantial on-chip memory. Housed in an LQFP144 package, this variant provides a balanced I/O count in a compact form factor, making it suitable for space-constrained automotive electronic control units (ECUs) requiring high performance and connectivity.
