GD32F1 is a new series product of 32-bit general-purpose, high-performance, and low-power MCU powered by the ARM® Cortex®-M3 core, suitable for a wide range of application scenarios. The GD32F1 product series integrates rich features to simplify system design and provide customers with a wide range of superior cost-effective MCU portfolios with proven technology and great innovations. Building on GigaDevice advanced gFlash technology and mass production experiences, it provides a new form of MCUs which offer customers high functionality and quality. The GD32F1 series is available in a lineup of basic, mainstream, connectivity, value, and performance.
The GD32F1 series of MCUs incorporates the 32-bit ARM® Cortex®-M3 core operating at 108MHz maximum frequency with Flash accesses zero wait states to obtain maximum efficiency. Meanwhile, it provides up to 3024KB on-chip Flash memory and up to 96KB SRAM. An extensive range of enhanced I/O ports and on-chip peripherals are connected to two APB buses. The MCU series provides up to three 12-bit 1MSPS ADCs and ten general-purpose 16-bit timers plus one PWM advanced timer, as well as standard and advanced communication interfaces.
The GD32F1 series of MCUs also brings many advantages to end-users. The maximum speed of GD32F1 series MCUs has been increased 50% than market's products. The code execution efficiency has been enhanced by 30% to 40% and power consumption had reduced by 20% to 30% in the same frequency. These performances provide maximum capability and bandwidth options for various market requirements.
The GD32F1 series of MCUs is widely suitable for fields of industrial control, human-machine interface, motor control, power monitor and alarm systems, consumer and handheld equipment, solar photovoltaic control, touch panel, and more.
