Product Description：

The GD32A714BIT3TB is a compact and cost-effective automotive microcontroller from GigaDevice's GD32A714 series. Powered by an Arm® Cortex®-M7 core running at up to 400MHz, it delivers reliable processing performance for a broad spectrum of automotive electronic control units. Designed to meet AEC-Q100 Grade 2 automotive reliability standards and supporting ISO 26262 functional safety development, it integrates essential automotive features, including a Hardware Security Module (HSM) for security foundations. Packaged in a space-saving LQFP100 format, this MCU is ideal for applications requiring a balance of performance, essential automotive connectivity, and a minimal PCB footprint.

Key Features：

Efficient Performance Core: Arm Cortex-M7 processor operating at up to 400MHz, equipped with a double-precision FPU, suitable for real-time control and embedded processing tasks common in automotive ECUs.

Automotive-Grade & Safe: Compliant with AEC-Q100 Grade 2 standards (operating temperature: -40°C to +105°C), designed to facilitate ISO 26262 ASIL-B functional safety development.

Integrated Security Hardware: Incorporates a Hardware Security Module (HSM) providing fundamental cryptographic functions (e.g., AES, TRNG) to establish trust anchors for secure boot and secure communication.

Sufficient On-Chip Memory: Features ample embedded Flash and SRAM (typical for the A714 series, e.g., ~1-2MB Flash, ~256-512KB SRAM) to accommodate automotive application code and data.

Standard Automotive Interfaces: Expected to include common automotive communication peripherals such as CAN FD, Ethernet (likely 10/100 or Gigabit), USB, and multiple serial interfaces (SPI, I²C, UART), though the exact count may be optimized for the package.

Analog and Control Capabilities: Includes analog-to-digital converters (ADC) and timers with PWM support for interfacing with sensors and driving actuators.

Compact Form Factor: Housed in a LQFP100 package, making it suitable for space-constrained ECU designs while maintaining good manufacturability.

Typical Applications：

Compact Body Control Modules: For control of lighting, door/window modules, or seat control units where space is limited.

Smart Sensor/Actuator Controllers: As the brain in advanced sensors (e.g., ultrasonic, radar) or smart actuators (e.g., LED matrix lighting, small motors) requiring local processing and network connectivity.

Local/Sub-Domain Controllers: In zonal architectures, managing a cluster of nearby sensors and actuators.

Vehicle Access Systems: For smart door handles, PEPS (Passive Entry Passive Start) controllers, or smart keys.

Basic Telematics or Connectivity Nodes: In cost-sensitive telematics boxes or Bluetooth/USB connectivity modules.

Industrial and Transportation: For applications in industrial control, commercial vehicle subsystems, or two-wheeler electronics where automotive-grade reliability is beneficial.
