GD32F103C8T6 Functional Description

ARM® Cortex™-M3 core

The most recent ARM® processor generation for embedded systems is the CortexTM-M3. It was created to offer a low-cost platform that satisfies MCU implementation requirements, has fewer pins and uses less power, and offers excellent computational performance and a sophisticated system response to interrupts.

• ARM® CortexTM-M3 processor core, 32 bits.
• A maximum operating frequency of 108 MHz.
• Hardware dividers and single-cycle multiplication.
• Nested Vectored Interrupt Controller integrated (NVIC).
• SysTick 24-bit timer.

Thumb and Thumb-2 instruction sets are supported by the CortexTM-M3 processor, which is based on the ARMv7 architecture. CortexTM-M3 also offers some of the following system peripherals:

Internal Bus Matrix connected with I-Code bus, System bus, D-Code bus, Private.

• Peripheral Bus (PPB) and debug accesses.
• Data Watchpoint and Trace (DWT).
• Instrumentation Trace Macrocell (ITM).
• Nested Vectored Interrupt Controller (NVIC).
• Flash Patch and Breakpoint (FPB).
• Serial Wire JTAG Debug Port (SWJ-DP).
• Trace Port Interface Unit (TPIU).
• Embedded Trace Macrocell (ETM).
• Memory Protection Unit (MPU).

On-chip memory

• Up to 3072 Kbytes of Flash memory
• Up to 96 Kbytes of SRAM

The Harvard architecture used in the design of the ARM® CortexTM-M3 processor design allows for the usage of independent buses for loading and storing data and retrieving instructions. The maximum amount of internal storage space for programs and data is 3072 Kbytes of inner Flash and 96 Kbytes of internal SRAM, both of which can be accessed (R/W) at CPU clock speed with no wait states.

Clock, reset, and supply management

• There are two options: an external 4 to 16 MHz crystal oscillator and an internal 8 MHz factory-tuned RC.
• System clock PLL with integration.
• Application supplies and I/Os ranging from 2.6 to 3.6 V. Supply supervisor features include low voltage detector, POR (Power On Reset), and PDR (Power Down Reset).

Numerous frequencies and clock operations are available through the Clock Control unit. These consist of the following:

• A Phase Lock Loop (PLL)
• A Low-Speed Internal 40K RC oscillator (IRC40K)
• A High-Speed crystal oscillator (HXTAL)
• A Low-Speed crystal oscillator (LXTAL)
• An Internal 40K RC oscillator (IRC40K)
• A High-Speed crystal oscillator (IRC40K)
• Clock prescalers Each Prescaler can customize the AHB
• APB2
• APB1 domain frequencies.

Power reset, system reset, and backup domain reset are three types of reset that GD32F10x Reset Control controls. Except for the SW-DP controller and the Backup domain, the system reset resets the processor core and peripheral IP components.

Both the power-on reset (POR) and the power-down reset (PDR) sTo guide the MCU into security, the embedded low voltage detector (LVD) continuously monitors the power supply, compares it to the voltage threshold, and creates an interrupt.

Frequently Asked Questions

What Is a 32-Bit Microcontroller?

A microcontroller is a component of a semiconductor chip that performs arithmetic processing and regulates the circuit through the I/O and peripheral interface, as you are undoubtedly already aware. The term “32-bit microcontroller” denotes a device that can perform arithmetic operations on 32-bit values. The 32-bit microcontroller executes a function in fewer instruction cycles than an 8-bit microcontroller because of its broader data bus.

Due to its excellent performance, a 32-bit microcontroller is frequently constructed with extra peripherals and memory. For instance, an 8-bit MCU cannot support the NXP LPC1700 series’ four 32-bit timers, SD/MMC, USB, Ethernet Mac, CAN, and other peripherals.

32-bit microcontrollers are power-hungry parts despite their strong performance and abundance of peripherals. Their higher operating frequencies, which range from tens to hundreds of Mhz, are used by them.

When Should You Use a 32-Bit Microcontroller?

You shouldn’t always use a 32-bit microcontroller for a project. It is more expensive than an 8-bit MCU to start. Some designs consider employing a 32-bit microcontroller to be excessive and an unnecessary expense.

Additionally, battery-powered circuits, like wireless IoT sensors, do not work well with 32-bit microcontrollers. They would rapidly deplete the battery while running at the slowest clock rate.

In these situations, 32-bit microcontrollers are a great option:

• When you require a microcontroller that can handle demanding data processing. As an illustration, consider a biometric controller that reacts quickly after comparing a fingerprint to thousands of records.
• When a microcontroller with several peripherals is required for a complicated circuit, in these circumstances, it is more cost-effective to employ a 32-bit microcontroller instead of a few logic ICs.
• When a program’s code size is too huge for an 8-bit microcontroller, larger flash memory is integrated into 32-bit microcontrollers.
