3.2.Nkọwa nke nchekwa

3.2.1.External Flash na SRAM

ESP32 na-akwado otutu QSPI flash mpụga na ebe nchekwa ohere ohere static (SRAM), nwere ihe nzuzo AES dabere na ngwaike iji chebe mmemme na data onye ọrụ.

ESP32 nweta QSPI Flash mpụga na SRAM site na caching. Ihe ruru 16 MB oghere koodu Flash mpụga ka etinyere na CPU, na-akwado ohere 8-bit, 16-bit na 32 bit, ma nwee ike mebe koodu.

Ihe ruru 8MB Flash mpụga na SRAM mapụtara na oghere data CPU, nkwado maka ịnweta 8-bit, 16-bit na 32-bit. Flash na-akwado naanị ọrụ ọgụgụ, SRAM na-akwado ọrụ ịgụ na ide.

ESP32-PICO-D4 4 MB nke agbakwunyere SPI Flash, enwere ike ịdepụta koodu ahụ na oghere CPU, nkwado maka ịnweta 8-bit, 16-bit na 32-bit, ma nwee ike mebe koodu. Pin GPIO6 ESP32 nke, GPIO7, GPIO8, GPIO9, GPIO10 na GPIO11 maka njikọ modul agbakwunyere SPI Flash, akwadoghị maka ọrụ ndị ọzọ.
