Value Line – GD32 ARM Cortex-M23 Microcontrollers

ARM Cortex M3

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.

Features

  • Cortex®-M23 Core Frequency up to 72 MHz​
  • Flash accesses 0-2 wait states
  • Single-cycle multiplier and 17-cycle divider​
  • Up to 28 maskable peripheral Interrupts, with 4 priority levels​
  • Flash size from 16KB to 64 KB​
  • SRAM size up to 8KB
  • 3KB ISP loader ROM​
  • Several Power saving modes, suitable for low power applications
  • 1 x 12bit, 1μs ADC (up to 10 chs)​
  • Up to 2 x USART and supports Irda/LIN/ISO7816​
  • Up to 2 x SPI (up to 18MHz clock frequency), 2 x I2S multiplexed​
  • Up to 2 x I2C (up to 1MHz clock frequency)​
  • 1 x 16 bit Advanced Timer, 5 x 16 bit GPTM,
  • 1 x 24bit SysTick Timer, 1 x 16 bit Basic Timer, 2 x WDG​
  • 5-chs DMA support: Timers, ADC, SPIs, I2Cs, USARTs and I2Ss​
  • System supervisor and reset: POR, PDR, LVD​
  • 80% GPIO available​
  • 32-bit CRC & 96-bit unique ID​
  • 2 x OP-AMP
  • 1 x Rail to Rail Comparator
  • On-chip clock: HSI (8MHz), LSI (40KHz)
  • 4x Independent Configurable Logic Array (CLA) units, supporting 16 input signals
  • A Look-up table(LUT) providing 256 programmable digital logic functions in each CLA unit
  • Programmable asynchronous and synchronous output
