Hi,
I am a hardware engineer and I'm very new to renesas microcontroller. I've sucessfully completed a simple project with RL78/G23 and impressed very much with the EMI/EMC performance. Now I want to use the RA8D1 Microcontroller for my next project.
I've choosen the RA8D1 microcontroller with 224pin and the project includes MIPI-DSI, 512M SRAM, RMII and need to interface the external NOR flash. This microcontroller is supports OSPI, but I like to interface 512M of QSPI NOR-Flash because I need to reduce the pin usage.
The RA8 MCU supports for OSPI, but I don't see the support of QSPI anywhere. Is it possible to use QSPI with RA8D1 MCU? If possible please provide a circuit diagram for QSPI flash interface with RA8D1
Thanks in advance

Hello,
You can use OSPI peripheral to access QSPI. Let me check it there is a sample code to provide.

Thank you. Sample code will be much useful for us.
Can you please give me a hardware connection diagram also? RA8D1 clock will be connected to the QSPI flash clock. What about the data lines. Do we need to connect D0-D3 or D4-D7 data line with Flash chip?
