Support for External RAM - ESP32 - — ESP-IDF Programming …
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).
Support for External RAM - ESP32-P4 - Espressif Systems
ESP32-P4 supports PSRAM connected in parallel with the SPI flash chip. While ESP32-P4 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). Some PSRAM chips are 1.8 V devices and some are 3.3 V.
ESP32 S3 DevKitC-1 N16R8 - using PSRAM - howto
2023年12月8日 · In my case it was sold as a ESP32-S3 N16R8 (indicating a flash size of 16MB and a PSRAM size of 8MB). The board itself was labeled ‘AI-S3’ on the back, nothing more (Example here). When looking at the config and pinout, I quickly realized it followed the ESP32-S3 DevKitC-1 design.
SPI Flash and External SPI RAM Configuration - ESP32-S3 - — …
Configure the PSRAM To enable PSRAM, please enable the CONFIG_SPIRAM under Component config / Hardware Settings menu. Then all the PSRAM related configurations will be visible under SPI RAM config menu.
Use PSRAM - uPesy
2022年12月23日 · PSRAM is an additional external 4 MB RAM that is present in some ESP32 modules: The ESP32 communicates with the PSRAM by the SPI protocol. This is why it is also called SPI RAM. The 3rd SPI bus of the ESP32 is used to communicate with the flash memory (which contains the program) and with the PSRAM.
