Greetings everyone, my company is developing a project where we need external memory for the ESP32. I read the documentation and developed a Schematic that I would like to validate here if possible. Here is the img:
https://docs.espressif.com/projects/esp ... l-ram.html but there is a detail that I didn't understand 100%:
This means that if I use other PSRAM than ESP-PSRAM32 I can't use API's to access it?
The memory that I found suitable for the project is this one : https://br.mouser.com/datasheet/2/198/I ... 488088.pdf
I made the connections based on the documentation Using External Memory on ESP32-WROOM

Re: Using External Memory on ESP32-WROOM
That RAM indeed is not supported. Suggest you switch to an ESP32-Wrover as it already supported RAM built in.

Especially considering the cost of that ram chip is more than the whole wrover module.

Re: Using External Memory on ESP32-WROOM
Thank you for you replies @WiFive and @ESP_Sprite, probably our project will use WROVER. If in the place of the SRAM I suggested, I used the official ESP-PSRAM32 from espressif, the design would be correct?
