wipy 3.0 esp32 chip id

Good morning,
can anyone tell me if in the wipy 3.0 the micro esp32 will be equipped with embedded flash?
Thank you -
@gferrara2016 Yes the Wipy3 has 8MB flash. See https://pycom.io/wp-content/uploads/2017/11/wipy3SpecsheetAugust2017.pdf for more details.

The ESP32 is the latest, version 1, with external RAM and Flash. -
@jmarcelino , and how about the deep sleep !

I am afraid that my question has been misunderstood, I am not referring to external flash memory accessible via SPI but to that possibly integrated into the microcontroller. For example, the ESP32-D2WD model is equipped with 16 Mbit of embedded Flash.

We don’t use the ESP32-D2WD because 16Mbit is the maximum for embedded flash and our new boards have 8MBytes (or 64Mbit)Functionally it’s the same just offers a smaller more integrated package.

@gferrara2016 If you look into the data sheet, you can read:
"From the ESP32 series of chips specified in this document, ESP32-D2WD has 16 Mbits of embedded flash, connected via pins GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1. The other chips in the ESP32 series have no embedded flash."
So the internal flash is connected too via a serial connection, blocking the SD card interface too. It is not connected to a memory bus. Therefore you would still for instance see a slow interrupt latency.

Thanks I already know these aspects!
