GD32VF103T4U6

General description

The GD32VF103 device is a 32-bit general-purpose microcontroller based on the RISC-V 

core with best ratio in terms of processing power, reduced power consumption and peripheral 

set. The RISC-V processor core is tightly coupled with an Enhancement Core-Local Interrupt 

Controller (ECLIC), SysTick timer and advanced debug support.

The GD32VF103 device incorporates the RISC-V 32-bit processor core operating at 108 MHz 

frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up 

to 128 KB on-chip Flash memory and 32 KB SRAM memory. An extensive range of enhanced 

I/Os and peripherals connect to two APB buses. The devices offer up to two 12-bit ADCs, up 

to two 12-bit DACs, up to four general 16-bit timers, two basic timers plus a PWM advanced 

timer, as well as standard and advanced communication interfaces: up to three SPIs, two

I2Cs, three USARTs, two UARTs, two I2Ss, two CANs, 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 the GD32VF103 devices suitable for a wide range of 

interconnection applications, especially in areas such as industrial control, motor drives, 

power monitor and alarm systems, consumer and handheld equipment, POS, vehicle GPS, 

LED display and so on.
