GD32F407RET6 LQFP-64(10x10) Arm® Cortex®-M4 32-bit MCU

GD32F407RET6 vs. MKE16F256VLH16

The GD32F407RET6 is a high-performance ARM Cortex-M4 microcontroller, offering a range of features that distinguish it from competitors like the MKE16F256VLH16. The GD32F407RET6 operates at a frequency of up to 168 MHz, which significantly outperforms the MKE16F256VLH16, which is limited to a maximum clock speed of 120 MHz. This higher clock speed enables faster processing, particularly in applications requiring high computational power.

In terms of memory, the GD32F407RET6 features 512 KB of Flash memory and 128 KB of SRAM, whereas the MKE16F256VLH16 offers 256 KB of Flash memory and 32 KB of SRAM. The increased memory capacity in the GD32F407RET6 ensures more room for complex applications and better multitasking performance, making it a more suitable option for demanding embedded systems.

The GD32F407RET6 also benefits from its integrated peripherals, including multiple I2C, SPI, UART, and CAN interfaces, which are comparable to the MKE16F256VLH16. However, the GD32F407RET6 provides more advanced peripherals like a 12-bit ADC with up to 3.6 Msps, a 32-bit timer, and a high-precision 12-bit DAC, which give it superior flexibility and control in a broader range of applications.

Overall, the GD32F407RET6 is better suited for high-performance and memory-intensive tasks, while the MKE16F256VLH16 is more limited in terms of both processing speed and memory.

GD32F407RET6 vs. STM32F446RET6

When comparing the GD32F407RET6 to the STM32F446RET6, both microcontrollers are built on the ARM Cortex-M4 core, but the GD32F407RET6 offers several key advantages in terms of performance and integration. While the STM32F446RET6 runs at a maximum frequency of 180 MHz, just slightly higher than the GD32F407RET6’s 168 MHz, the performance difference between the two chips is negligible for most practical applications.

However, the GD32F407RET6 stands out in terms of its peripheral features and overall integration. For example, the GD32F407RET6 includes up to 112 I/O pins, which provides more connectivity options than the STM32F446RET6, which offers a maximum of 82 I/O pins. This increased I/O capability is particularly advantageous in designs that require extensive peripheral connections.

The GD32F407RET6 also has superior memory performance with 512 KB Flash and 128 KB SRAM, compared to the STM32F446RET6, which offers 512 KB Flash but only 128 KB of SRAM. While both have similar Flash memory sizes, the higher SRAM capacity in the GD32F407RET6 makes it a more effective choice for applications that demand large buffers or require faster data access.

Another important aspect is the cost-effectiveness of the GD32F407RET6. In general, GD32 microcontrollers are known for offering competitive pricing compared to the STM32 series. This provides customers with an excellent balance between cost and performance, making the GD32F407RET6 a highly attractive option for budget-conscious projects without sacrificing processing power or peripheral support.

Conclusion

In summary, the GD32F407RET6 outperforms its competitors, including the MKE16F256VLH16 and STM32F446RET6, in several key areas:

• Higher processing speed: 168 MHz (vs. 120 MHz and 180 MHz)

• Superior memory capacity: 512 KB Flash and 128 KB SRAM (vs. 256 KB Flash and 32 KB SRAM for MKE16F256VLH16)

• More I/O pins: Up to 112 pins (vs. 82 pins on STM32F446RET6)

• Cost-effectiveness: Competitive pricing without sacrificing quality or performance

These advantages make the GD32F407RET6 an ideal choice for customers seeking a high-performance microcontroller with superior integration, more memory, and greater flexibility at a lower cost.
