GD32F470IIH6

General description

The GD32F470xx device belongs to the stretch 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 features a Floating Point Unit (FPU) 

that accelerates single precision floating point math operations and supports all Arm® single

precision instructions and data types. It 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 GD32F470xx device incorporates the Arm® Cortex®-M4 32-bit processor core operating 

at 240 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It 

provides up to 3072 KB on-chip Flash memory and 768 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 2.6 MSPS ADCs, two 12-bit DACs, up to eight general 16-bit timers, two 16-

bit PWM advanced timers, two 32-bit general timers, and two 16-bit basic timers, as well as 

standard and advanced communication interfaces: up to six SPIs, three I2Cs, four USARTs

and four UARTs, two I2Ss, two CANs, a SDIO, USBFS and USBHS, and an ENET. Additional 

peripherals as Digital camera interface (DCI), EXMC interface with SDRAM extension support,

TFT-LCD Interface (TLI) and Image Processing Accelerator (IPA) are included.

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

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

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

applications.

The above features make GD32F470xx 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.
