¡El 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. ¡El 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. ¡El 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. ¡El 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. ¡El 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. ¡El 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.
