PSRAM chip used in ESP32-S3-WROOM-2-N32R16V module

[MERAGA]

Hello Espressif community,

I am an individual developer working with the ESP32-S3 SoC.
I am currently planning a design that requires external PSRAM, and I want to ensure compatibility with officially validated chips.

Could anyone provide the manufacturer and part number of the PSRAM used inside the ESP32-S3-WROOM-2-N32R16V module?
I am not representing a company; this is for a personal project.

Any guidance would be greatly appreciated. Thank you!

I have not tried but as per the specs for wroom2 it uses Octal SPI for PSRAM
What I know based on my own endowers is that you can look for Oct SPI RAM from vendors like APMemory or Winbond
Or just look for APS6408L or APS12808L series from these vendors

Hope it helps

Thanks for helping!
Acording to my research, Espressif using APS12808L series for modules. All of APS12808L features is same with features of ESP32-S3-WROOM-2-N32R16V module's RAM's.

ESP32 supports PSRAM connected in parallel with the SPI flash chip. While ESP32 is capable of supporting several types of RAM chips, ESP-IDF currently only supports Espressif branded PSRAM chips (e.g., ESP-PSRAM32, ESP-PSRAM64, etc).
