First question asked Welcome!

Hello,
We are using this type of a memory in our board.
We are using it as SPI communication with CLK frequency 20 MHz.
We want to connect EEPROM SPI memory with the NOR Flash. The problem is the chosen EEPROM SPI memory runs at 10 MHz CLK. Is it possible to lower the frequency of the NOR FLASH to 10 MHz and to connect the EEPROM with the signals CLK, MOSI, MISO and two CS for both chips?
Thank you in advance!
Best regards,
Ana Ilieva

Hello,

 

Thank you for contacting Infineon Technologies.

Clock frequency of NOR FLASH is controlled by master (MCU) if you set clock frequency of master 10 MHz it should work totally fine.
