EMB1428QSQ/NOPB is used which has the frequency of the 1.1MHz fclk and the SPI2 of STM32F469BIT7 is going as a clock to it. I need the minimum value of the SPI2 master that can be fed to the EMB1428QSQ/NOPB. Also, where can I find the minimum frequency of the communication interfaces , I have used the USART and SPI2.

Hello,
Why are you looking for the minimum freq value?
Only maximum values are provided in the datasheet:
And you can go downto 1MHz for SPI

The minimum required by the EMB1428QSQ will be specified in the EMB1428QSQ datasheet;
The minimum that can be provided from the STM32 will be specified in the STM32 datasheet and/or Reference Manual:
