Can Espressif ESP8266ex function as a WiFi adapter (not a standalone microcontroller) without external flash memory ?
In the documentation " There is no programmable ROM in the SoC, therefore, user program must be stored in an external SPI flash ", " serving as a WiFi adapter, wireless internet access can be added to any micro controller based design with simple connectivity (SPI/SDIO or I2C/UART interface) " (External flash on SPI would occupy a port), " Depending on the address, the AHB data requests can go into one of the two slaves: APB block, or flash controller (usually for standalone applications). "
