Hi,

 

I would like to understand if Cyclone 4 PN: EP4CE75F29C6N can support I2C interface with up to 1Mhz?

if not, can you recommend Other Cyclone device that supprt this rate?

Thanks,

Meital

I suppose, any Intel programmable logic device can.

I think the device is capable of supporting the I2C interface with up to 1 MHz. It has sufficient resources, such as programmable logic elements (LEs) and I/O pins, to implement an I2C interface with a clock frequency of 1 MHz.


In Quartus Prime, you can use the Timing Analyzer tool to analyze the timing of your design and check if the timing requirements of the I2C interface are being met. The Timing Analyzer takes into account the design constraints and provides detailed information about the setup and hold violations, slack, and other timing metrics. By analyzing the timing reports, you can determine if the I2C interface can operate reliably at the desired frequency.


If you are looking for other Cyclone devices that support the same I2C rate, you can consider other members of the Cyclone IV FPGA family or even explore newer FPGA families such as Cyclone V or Cyclone 10. 


You can refer to the respective device datasheets and documentation provided by Intel FPGA to get more detailed information about each FPGA family and choose the one that best fits your needs.
