Re: ESP32-S3R8 with S25FL064L SPI Flash not working

Thank you very much for the suggestion, it worked!

It is a bit weird why the DIO is not working with this Flash IC.
Do you have any idea or suggestion why it was not working?

ESP32-S3R8 with S25FL064L SPI Flash not working

I have design based around ESP32-S3R8, which uses S25FL064L SPI Flash (datasheet: https://www.infineon.com/dgdl/Infineon-S25FL064L_64-Mbit_8-Mbyte_3-DataSheet-v09_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ee2d2846996 ) as the main flash. After I program the MCU with any sample code, I always receive log...

Re: ESP32-S3R8 PSRAM GPIOs

Is it possible to utilize GPIOs Input Enabled and Output Enable control signals, to disconnect the GPIO from the physical pad?
Or this will cause issues with the PSRAM?

ESP32-S3R8 PSRAM GPIOs

Hello there, I have custom design based on ESP32-S3R8, and by mistake I connected two pins used by the in-package PSRAM, GPIO36 and GPIO37, to another component in the design, which can utilize the state of those two pins to enter low-power mode and reset. Fortunately, the component can function pro...
