Comparison
Now that we have provided overviews of the EC712 and EC1155, let's compare them side by side to understand the key differences between these two ERCs:
1. CPU frequency: The EC712 has a maximum CPU frequency of 80 MHz, while the EC1155 offers a higher maximum frequency of 130 MHz. This means that the EC1155 is generally faster and more capable than the EC712.
2. RAM and FLASH: The EC712 has a smaller RAM and FLASH memory capacity compared to the EC1155. The EC712 offers up to 64 kB FLASH and up to 80 kB RAM, while the EC1155 offers up to 192 kB RAM and 80 kB FLASH. This means that the EC1155 has more memory resources available for your project.
3. Analog inputs: The EC712 offers up to 8 analog inputs, while the EC1155 offers up to 16 analog inputs. If you need more analog input capabilities, the EC1155 is the better choice.
4. USB ports: Both the EC712 and EC1155 offer up to 4 USB ports, but the EC1155 supports USB 2.0 while the EC712 supports USB 1.1. If you need to connect to higher-speed devices, the EC1155 is the better choice.
5. Interrupt and I/O ports: The EC712 and EC1155 both offer similar sets of interrupt and I/O ports, including 3 UARTs, 2 SPI, 2 I2C, and 1 1-wire ports. However, the EC1155 offers a few additional ports for a total of 7 I/O ports.
6. DMA channels: Both the EC712 and EC1155 offer 4 DMA channels. This is a comparable feature, as both devices offer the same number of DMA channels.
7. PLL, DC-DC, and charge pump controllers: Both the EC712 and EC1155 offer 32-bit PLL, DC-DC, and charge pump controllers. This is a comparable feature, as both devices offer the same number of advanced controllers.
In conclusion, the EC712 and EC1155 both offer a wide range of features and capabilities. However, the EC1155 has a higher CPU frequency, more memory resources, and additional I/O ports compared to the EC712. If speed and more capabilities are important factors in your decision, the EC1155 is the better choice. However, if you need to support fewer analog inputs or connect to higher-speed devices, the EC712 may be a better fit. In many cases, these two ERCs offer comparable performance and features, so it is important to consider your specific application needs and requirements when making your decision.
