Description:

The GD32A741BVT3TB is a top-tier automotive-grade microcontroller from GigaDevice, built around a high-performance 350 MHz Arm® Cortex®-M7 core. It is specifically designed for next-generation centralized vehicle E/E architectures, integrating a Time-Sensitive Networking (TSN)-enabled Ethernet MAC to support deterministic, high-bandwidth data communication. Combined with an embedded Hardware Security Module (HSM) for robust cryptographic operations, rich CAN FD interfaces, and comprehensive functional safety features targeting ASIL-B, this MCU provides a powerful, secure, and reliable computing platform for critical automotive domains and high-speed gateways.

Features:

High-Performance Core: Arm® Cortex®-M7 at up to 350 MHz with Double-Precision FPU and 32KB I-Cache / 32KB D-Cache.

Advanced Networking: Integrated 10/100M Ethernet MAC supporting key Time-Sensitive Networking (TSN) standards (IEEE 802.1AS, 802.1Qbv) for deterministic, low-latency communication.

Hardware Security Module (HSM): Dedicated security coprocessor supporting AES-128/192/256, SHA-1/224/256, and TRNG, providing a secure foundation for vehicle communication and OTA updates.

Automotive Connectivity: 4x CAN FD controllers, multiple USARTs, I2Cs, SPIs, and 1x SDIO for comprehensive network integration.

Large Memory Configuration: 2MB of embedded Flash and 512KB SRAM (including 128KB TCM) to accommodate large, complex application code and data buffers.

Automotive & Safety: AEC-Q100 Grade 2 qualified. Hardware features (ECC, Memory Parity, Dual Watchdogs, Clock/Power Monitoring) supporting system development to ASIL-B per ISO 26262.

High-Precision Analog: Three 16-bit 4.2 MSPS ADCs (up to 24 channels) and two 12-bit DACs.

Package: LQFP100.

Applications:

Central Gateway / Domain Controller: High-performance central compute node for zone-based architecture, handling multi-network routing with TSN synchronization.

Vehicle Central Computing Unit: Core processing unit for integrated cockpit, body, and chassis control.

Advanced Driver Assistance Systems (ADAS): Centralized ADAS domain controller processing data from multiple sensors (cameras, radars).

Smart Zone Controller: High-performance zone ECU managing local actuators and sensors with secure gateway functionality.

Connected Vehicle Telematics: Secure telematics control unit (TCU) with high-speed connectivity and advanced security for V2X and OTA.
