Product Description：

The GD32A724BIT3TB is a compact yet powerful variant of GigaDevice's GD32A724 automotive microcontroller series. It delivers high-performance computing through its Arm® Cortex®-M7 core, operating at up to 500MHz, making it suitable for demanding real-time processing tasks within space-constrained electronic control units (ECUs). This MCU maintains the series' commitment to automotive-grade reliability (AEC-Q100 Grade 2) and functional safety (ISO 26262 support), while integrating critical features such as a Hardware Security Module (HSM) for cybersecurity and essential high-speed communication interfaces like automotive Ethernet and CAN FD. Packaged in a LQFP100 form factor, it is the optimal solution for applications that require a significant computational punch and modern connectivity, but must fit within a minimized PCB footprint, such as compact domain controllers or advanced smart actuators.

Key Features：

High-Performance Core in Small Form Factor: Features an Arm Cortex-M7 processor running at up to 500MHz with double-precision FPU and DSP extensions, providing substantial processing power for algorithm execution and signal processing within a compact package.

Integrated Automotive Security: Equipped with a Hardware Security Module (HSM) containing cryptographic accelerators (e.g., AES, SHA, TRNG) to establish a root of trust, enable secure boot, and protect vehicle communications.

Automotive Qualification & Safety: Compliant with AEC-Q100 Grade 2 standards (operating temperature: -40°C to +105°C). Designed to aid in the development of systems targeting ISO 26262 ASIL-B functional safety level.

Focused High-Speed Connectivity: Offers a strategic selection of automotive network interfaces, which typically include:

Gigabit Ethernet (potentially with TSN support) for high-bandwidth data links.

Multiple CAN FD channels for deterministic in-vehicle networking.

A complement of serial interfaces (USB, SPI, I²C, UART) for peripheral expansion.

(Note: The exact number of channels may be optimized for the LQFP100 pin count.)

Substantial Memory Resources: Contains generous on-chip memory (estimated ~2-3MB Flash, ~512KB-1MB SRAM, aligned with series positioning) to accommodate complex application code, real-time operating systems, and communication protocol stacks.

Precision Analog & Control: Integrates analog-to-digital converters (ADC), digital-to-analog converters (DAC), and advanced timers for accurate system monitoring, sensor interfacing, and precise actuator control (e.g., PWM generation).

Space-Efficient Package: Housed in an LQFP100 package, delivering an excellent balance of performance, I/O capability, and a reduced PCB area for design miniaturization.

Typical Applications：

Compact Domain Controllers: For body or comfort domains where high processing power is needed but physical space is limited, integrating functions like advanced lighting control, climate management, and access systems.

Advanced Smart Actuator Controllers: Powering complex actuators such as adaptive dampers in suspension systems, advanced thermal management valves, or high-resolution matrix LED drivers.

Localized Zonal/Zone Controllers: Serving as a high-performance processing node within a vehicle's zonal architecture, handling data aggregation and control for a specific zone.

High-Performance Sensor Fusion Modules: For radar or lidar preprocessing units that require significant local computation before sending fused data to a central computer.

Electric Vehicle Auxiliary Control Units: In On-Board Charger (OBC) control or advanced Battery Management System (BMS) modules where computational demands for algorithms and communication are high.

Industrial Drives & Automation: For compact, high-speed motor drives and programmable logic controllers (PLCs) that benefit from automotive-grade reliability and processing power.
