Hi,

I'd like to confirm maximum through rate of SPI communication regarding two products CY8C624AAZI-S2D04 and CY8C6245AZI-S3D02.

These products will be able to choose octal SPI and through rate is 640Mbps. Is my understanding correct?

I found description "Supports single, dual, quad, dual-quad, and octal interfaces w/ throughput up to 640 Mbps" in datasheet.

Best regards,

Shohei

Hi Shohei,

Yes, if the SMIF runs at 80MHz and with 8bits you will receive a theoretical throughput of 640Mbps.

From that you have to remove some overhead for controlling the external memory etc.
