As this is a 3.3V device, it can be used with ESP-WROM-32 and all boards using 3.3V Flash.
I’ve tested the chip on Adafruit HUZZAH32 – ESP32 Feather Board which has ESP-WROOM-32 module with rev1 ESP32.
I removed the ESP-WROOM-32 shield, replaced the Flash with Winbond’s 3.3V 16 MB Flash, and connected the IPS6404L-SQ-SPN and 10K pull-up to GPIO16.
The SPIRAM was recognized (as well as 16MB Flash).
I’ve tested the SPIRAM functionality extensively for more tha 24 hours and there were no problems.
Tested with Flash (in QIO mode) & SPIRAM running at 40MHZ and 80MHz.

@Borislav Lovosevic: when you add more psrams. What do you modify anything in code ? Or just only using default code, which using in ESP-wrover?
Thanks.
