The GD32E518CET6 is a high-performance general-purpose microcontroller from GigaDevice, featuring an LQFP48 surface-mount package with a main frequency of up to 180MHz. It is equipped with a Cortex-M33 core, built-in hardware FPU for floating-point operations, DSP acceleration, and a TMU trigonometric hardware accelerator, significantly reducing computational pressure for motor control, frequency conversion, and signal processing algorithms. It includes 512KB of large-capacity program flash memory and 128KB of high-speed SRAM, supporting dual-bank partition read/write operations and an MPU for memory isolation to enhance operational stability. Integrated with comprehensive industrial connectivity peripherals, it features three CAN-FD buses, a 100M Ethernet MAC, USB high-speed OTG, multiple high-precision ADC/DAC modules, high-speed comparators, and an ultra-high-resolution HRTIM timer, making it suitable for digital switch-mode power supplies, servo motor drives, industrial acquisition instruments, and smart gateway devices. Operating at 1.7V–3.6V with 5V-tolerant I/O, it ensures stable performance across an industrial temperature range of -40°C to 85°C and offers multiple low-power modes to balance high performance with standby efficiency. Pin-compatible with other GD32E5 series MCUs in the same package, it serves as a cost-effective alternative to imported STM32F4/F7 solutions. Available in original factory packaging with tape and reel, samples are ready for shipment. Applications Industrial automation controllers, servo/BLDC motor drives, digital power supplies, photovoltaic inverters, high-precision measurement instruments, industrial gateways, automotive control, high-end energy storage systems, and smart medical devices.
