GD32F303VET6

General description

The GD32F303xx device belongs to the mainstream line of GD32 MCU Family. It is a new 

32-bit general-purpose microcontroller based on the Arm® Cortex®

-M4 RISC core with best 

cost-performance ratio in terms of enhanced processing capacity, reduced power 

consumption and peripheral set. The Cortex®

-M4 core features implements a full set of DSP

instructions to address digital signal control markets that demand an efficient, easy-to-use 

blend of control and signal processing capabilities. It also provides a Memory Protection Unit 

(MPU) and powerful trace technology for enhanced application security and advanced debug 

support.

The GD32F303xx device incorporates the Arm® Cortex®

-M4 32-bit processor core operating 

at 120 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It 

provides up to 3072KB on-chipFlash memory and 96KB SRAM memory. An extensive range 

of enhanced I/Os and peripherals connected to two APB buses. The devices offer up to three

12-bit 2.6 MSPS ADCs, two 12-bit DACs, up to ten general 16-bit timers, two 16-bit PWM 

advanced timers, and two 16-bit basic timers, as well as standard and advanced 

communication interfaces: up to three SPIs, two I2Cs, three USARTs and two UARTs, two

I2Ss, a USBD, a CAN and a SDIO.

The device operates from a 2.6 to 3.6 V power supply and available in (–20 to +85 °C) / (–40 

to +85 °C) / (–40 to +105 °C) temperature range. Several power saving modes provide the 

flexibility for maximum optimization between wakeup latency and power consumption, an 

especially important consideration in low power applications.

The above features make GD32F303xx devices suitable for a wide range of interconnection 

and advanced applications, especially in areas such as industrial control, motor drives, 

consumer and handheld equipment, human machine interface, security and alarm systems,

POS, automotive navigation, IoT and so on.
