Description

Product Overview

The GD32F405RET6 is a high-performance 32-bit microcontroller from GigaDevice (兆易创新) based on the ARM Cortex-M4 core with FPU and DSP extensions, running at 168 MHz. It integrates 512 KB Flash, 192 KB SRAM, and up to 51 GPIOs in an LQFP64 package. The device offers rich peripherals including USB 2.0 FS+HS OTG, dual CAN 2.0B, three 12-bit ADCs at 2.6 MSPS, two 12-bit DACs, and multiple communication interfaces. It is pin-compatible with the ST STM32F405RGT6 for easy design migration.

The GD32F405RET6 is a high-performance 32-bit MCU from GigaDevice based on the ARM Cortex-M4 core with FPU and DSP extensions running at 168MHz. It features 512KB Flash, 192KB SRAM, and up to 51 GPIOs in LQFP64 package. Rich peripherals include 4+2 USART/UART, 3 I2C, 3 SPI, 2 I2S, 2 CAN 2.0B, USB 2.0 FS+HS OTG, SDIO, camera interface, 3×12-bit ADCs (2.6MSPS), and 2×12-bit DACs. Pin-compatible with STM32F405RGT6 for easy migration.

The Cortex-M4 core executes Thumb-2 instructions with single-cycle MAC and hardware FPU. Internal 16MHz RC or external 4-32MHz crystal feeds PLL to generate 168MHz system clock. AHB runs at 168MHz, APB1 at 42MHz, APB2 at 84MHz via bus matrix connecting Flash, SRAM, and peripherals. Three independent 12-bit SAR ADCs support single/continuous/scan/discontinuous modes with hardware oversampling up to 16-bit equivalent. A 30KB Boot ROM provides ISP via USART0/2 or USB DFU. Three low-power modes (Sleep, Deep-sleep, Standby) minimize power consumption.
