GD32F403VCH6

General description

The GD32F403xx device belongs to the performance 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 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 GD32F403xx device incorporates the Arm® Cortex®-M4 32-bit processor core operating 

at 168 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It 

provides up to 3072 KB on-chip Flash memory and 128 KB SRAM memory. An extensive 

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

to three 12-bit 2.6M MSPS ADCs, two 12-bit DACs, up to eight general-purpose 16-bit timers, 

two 16-bit PWM advanced-control 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, two CANs, a SDIO, and an USBFS.

The device operates from a 2.6 to 3.6 V power supply and available in –40 to +85 °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 GD32F403xx devices suitable for a wide range of interconnection 

and advanced applications, especially in areas such as industrial control, consumer and 

handheld equipment, embedded modules, human machine interface, security and alarm 

systems, graphic display, automotive navigation, drone, IoT and so on.
