GD32F330K4T6

General description

The GD32F330xx device belongs to the value line of GD32 MCU family. It is a new 32-bit

general-purpose microcontroller based on the Arm® Cortex®-M4 RISC core with best costperformance ratio in terms of enhanced processing capacity, reduced power consumption 

and peripheral set. The Cortex®-M4 core features implement 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 powerful trace technology for enhanced 

application security and advanced debug support.

The GD32F330xx device incorporates the Arm® Cortex®-M4 32-bit processor core operating 

at 84 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It 

provides up to 128 KB on-chip Flash memory and up to 16 KB SRAM memory. An extensive 

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

12-bit ADC, up to five general 16-bit timers, a general 32-bit timer, a PWM advanced timer, 

as well as standard and advanced communication interfaces: up to two SPIs, two I2Cs, two 

USARTs.

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 GD32F330xx devices suitable for a wide range of applications, 

especially in areas such as industrial control, motor drives, user interface, power monitor and 

alarm systems, consumer and handheld equipment, gaming and GPS, E-bike and so on.
