General description
The GD32F310xx device belongs to the value line of GD32 MCU family. It is a new 32-bit
general-purpose microcontroller based on the Arm® Cortex®-M4 RISC core with best costperformance
ratio in terms of enhanced processing capacity, reduced power consumption
and peripheral set. The Cortex®-M4 core features implement 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 powerful trace technology for enhanced
application security and advanced debug support.
The GD32F310xx device incorporates the Arm® Cortex®-M4 32-bit processor core operating
at 72 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It
provides up to 64 KB on-chip Flash memory and up to 8 KB SRAM memory. An extensive
range of enhanced I/Os and peripherals connected to two APB buses. The devices offer one
12-bit ADC, up to five general 16-bit timers, a PWM advanced timer, as well as standard and
advanced communication interfaces: up to two SPIs, two I2Cs, an I2S, two USARTs.
The device operates from a 2.6 to 3.6 V power supply and available in –40 to +85 °C
temperature range for grade 6 devices, or –40 to +105 °C temperature range for grade 7
devices. Several power saving modes provide the flexibility for maximum optimization
between wakeup latency and power consumption, an especially important consideration in
low power applications.
The above features make the GD32F310xx devices suitable for a wide range of applications,
especially in areas such as industrial control, motor drives, user interface, power monitor and
alarm systems, consumer and handheld equipment, gaming and GPS, E-bike and so on.
