GD32F103xx device is an Arm based device ®  The 32-bit general-purpose microcontroller of Cortex-M3 ® RISC core has the best ratio in processing power, low power consumption, and peripheral settings. Cortex-M3 ® is the next-generation processor kernel that is tightly coupled with Nested Vector Interrupt Controllers (NVICs), SysTick timers, and advanced debugging support. GD32F103xx device uses Arm ®  The Cortex-M3 ® 32-bit processor core operates at a frequency of 108 MHz and has zero wait state for flash memory access for maximum efficiency. It provides up to 3 MB of on-chip flash memory and up to 96 KB of SRAM memory. Various enhanced I/O and peripherals connected to two APB buses.
These devices provide up to 3 12 bit ADCs, up to 2 12 bit DACs, up to 10 universal 16 bit timers, 2 basic timers, and 2 PWM advanced timers, as well as standard and advanced communication interfaces: up to 3 SPIs, 2 I2Cs, 3 USARTs, 2 UARTs, 2 I2S, 1 USBD, 1 CAN, and 1 SDIO. The device is powered by a 2.6V to 3.6V power supply, with a temperature range of -40 to+85 ° C. Multiple power-saving modes provide flexibility to achieve maximum optimization between wake-up delay and power consumption, which is particularly important in low-power applications.
The above characteristics of GD32F103RBT6 make GD32F103xx devices suitable for a wide range of applications, especially in industrial control, motor drive, power monitoring and alarm systems, consumer and handheld devices, POS, in car GPS, visual intercom, PC peripheral devices, and other fields.
