description
The GD32E230xx device belongs to the value line of GD32 MCU family. It is a new 32-bit
general-purpose microcontroller based on the ARM® Cortex®-M23 core. The Cortex-M23
processor is an energy-efficient processor with a very low gate count. It is intended to be used
for microcontroller and deeply embedded applications that require an area-optimized
processor. The processor delivers high energy efficiency through a small but powerful
instruction set and extensively optimized design, providing high-end processing hardware
including a single-cycle multiplier and a 17-cycle divider.
The GD32E230xx device incorporates the ARM® Cortex®-M23 32-bit processor core
operating at up to 72 MHz frequency with Flash accesses 0~2 wait states to obtain maximum
efficiency. It provides up to 64 KB embedded 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 and one comparator, up to five general 16-bit timers, a basic
timer, a PWM advanced timer, as well as standard and advanced communication interfaces:
up to two SPIs, two I2Cs, two USARTs, and an I2S.
The device operates from a 1.8 to 3.6 V power supply and available in –40 to +85 °C
temperature range. 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 GD32E230xx 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.
