ESP32 Flash Memory manufacturer ID's

Postby vvb333007 » Tue May 13, 2025 3:05 am

Hello everyone!

Does anybody know which Flash Memory chips are usually used by Espressif for their modules? Modules I have all have memory chips with ID 0x5E (Puya Semiconductor?).
Thanks!
Slava.

Digging ESP-IDF sources gave me this list:

Code: Select all

    case 0xc8: mfg =  "Giga Device"; break;
    case 0x68: mfg =  "Boya"; break;
    case 0x9d: mfg =  "ISSI"; break;
    case 0xc2: mfg =  "MXIC"; break;
    case 0xcd: mfg =  "TH"; break;
    case 0xef: mfg =  "WinBond"; break;
Who is 0x5e then? My board is generic ESP32-WROOM32D, Q5 CPU, ver 3.01
Thanks!
Slava.
