GD32F205RCT6

General description

The GD32F205xx device belongs to the performance line of GD32 MCU Family. It is a new 

32-bit general-purpose microcontroller based on the ARM® Cortex®-M3 RISC core with best 

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

peripheral set. The Cortex®-M3 is a next generation processor core which is tightly coupled 

with a Nested Vectored Interrupt Controller (NVIC), SysTick timer and advanced debug 

support.

The GD32F205xx device incorporates the ARM® Cortex®-M3 32-bit processor core operating 

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

provides up to 3072 KB on-chip flash memory and 256 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 MSPS ADCs, two 12-bit DACs, up to ten 16-bit general timers, two 16-bit 

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

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

I2Ss, two CANs, a SDIO, a USBFS. Additional peripherals as TFT-LCD Interface (TLI) and 

EXMC interface with SDRAM extension support are included.

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

temperature range. Several power saving modes provide the flexibility for maximum 

optimization of power consumption, an especially important consideration in low power 

applications.

The above features make GD32F205xx 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, automotive navigation and so on.
