GD32F330C6T6 vs. STM32F334C6T6: Superior Performance and Memory Capacity

The GD32F330C6T6 and STM32F334C6T6 both feature ARM Cortex-M4 cores running at 72 MHz, but the GD32F330C6T6 offers superior memory capacity and system integration. The GD32F330C6T6 comes with 128 KB of Flash and 32 KB of SRAM, compared to the STM32F334C6T6, which offers 128 KB of Flash and 24 KB of SRAM. The increased SRAM in the GD32F330C6T6 provides more memory for processing data, buffering, and running larger or more complex codebases, which is beneficial for applications such as industrial control systems or complex sensor networks.

Additionally, the GD32F330C6T6 offers a higher level of integration with its peripheral set, including USART, SPI, I2C, and CAN interfaces. The STM32F334C6T6 also supports similar communication interfaces, but the GD32F330C6T6 excels with more advanced timers and PWM functionality, making it ideal for motor control and precision industrial applications.

GD32F330C6T6 vs. STM32F303C6T6: Enhanced Power Management and Performance

Both the GD32F330C6T6 and STM32F303C6T6 are equipped with the ARM Cortex-M4 core, operating at 72 MHz. However, the GD32F330C6T6 provides better overall performance and efficiency due to its optimized power management features. While both chips support low-power modes, the GD32F330C6T6 offers enhanced power-saving capabilities, making it more suitable for battery-operated devices and long-term field operations.

Furthermore, the GD32F330C6T6 offers 32 KB of SRAM, which is an improvement over the STM32F303C6T6's 48 KB of SRAM, providing better memory management for real-time processing and more complex data handling. The GD32F330C6T6's power optimization helps extend battery life in power-critical applications, especially for IoT and wearable devices where low-energy consumption is crucial.

GD32F330C6T6 vs. STM32F334C4T6: Higher SRAM and Better Peripheral Set

The GD32F330C6T6 and STM32F334C4T6 both offer 128 KB of Flash memory, but the GD32F330C6T6 provides 32 KB of SRAM, while the STM32F334C4T6 only provides 16 KB of SRAM. This difference in SRAM capacity enables the GD32F330C6T6 to handle larger and more complex applications with higher memory requirements. The 32 KB SRAM in the GD32F330C6T6 allows for greater efficiency in handling real-time data and supports more advanced applications, including data logging and sensor processing.

In addition to SRAM advantage, the GD32F330C6T6 provides a richer set of peripheral options, including enhanced timing features such as PWM, advanced timers, and more sophisticated ADCs. The STM32F334C4T6 has similar basic peripherals, but its lower SRAM and less extensive timer and PWM functionality limit its capability in precision control and high-frequency applications. Therefore, the GD32F330C6T6 is better suited for industrial and motor control applications that demand more robust timing and control systems.
