Description:

The GD32A724AIT3TB is a top-tier member of GigaDevice's GD32A7 series, specifically belonging to the GD32A74x sub-family. Based on the high-performance Arm Cortex-M7 core, this MCU is engineered to deliver robust computing power, the highest functional safety level (ASIL-D), and comprehensive in-vehicle networking capabilities for the most demanding safety-critical automotive applications.

Features:

Core: Employs the ultra-high-performance Arm Cortex-M7 core. The series offers three configuration options: single-core, dual-core, and single-core lockstep. It operates at 160 MHz, delivering computing power up to 763 DMIPS.

Memory: The series supports up to 4 MB of on-chip Flash and 512 KB of SRAM, featuring dual-bank Flash for seamless OTA (Over-The-Air) updates.

Reliability: Compliant with AEC-Q100 Grade 1 standards, operating temperature range: -40°C to +125°C.

In-Vehicle Network: Integrated 8x CAN FD, 12x LIN, 6x SENT, and 1x 10/100M Ethernet supporting AVB/TSN.

Safety and Security: This is the most critical differentiator. As part of the GD32A74x sub-series, it complies with the highest functional safety standard ISO 26262 ASIL-D. It meets EVITA-full information security requirements and supports Chinese cryptographic algorithms (SM2/SM3/SM4).

Software Ecosystem: Supports AUTOSAR architecture and provides MCAL (Microcontroller Abstraction Layer), compatible with mainstream compilers and debuggers.

Applications:

Body Domain Controller (BDC) with high safety requirements

Chassis Applications

Battery Management System (BMS)

On-Board Charger (OBC) and DC-DC Converter

Other automotive control systems with extremely high functional safety level requirements
