ESP32 16MB flash module identification on cover

Hello,
I noticed that newer ESP32-WROVER-B/IB or ESP32-WROOM-32D modules with 16MB flash have XX0H28 on cover. From "Product Ordering Information" I found that ESP32 with 16MB flash has H28 code in "Manufacturer Part Number". Is that right?

Looks like you have already identified it?
I just received my order for "ESPRESSIF ESP32-WROOM-32E" with flash of 4, 8, 16 MB flash, and the covers have the imprint of:
XX0H32
XX0H64
XX0H28
respectively.
I haven't tested yet but the imprint at least looks like the flash in MBit with the "1" of "128" dropped.

I can now confirm that the chips are 'revision 3' and are indeed 4, 8, 16 MB.
The tests were done with the attached CHIPTEST script. It runs with auto-partitioning under UECIDE
https://uecide.org/ When used under Arduino IDE you need to set the partitions manually.
This is part of the outcome for the 16 MB chip:
Code: Select all
partition addr: 0x290000; size: 0xd70000; label: ffat
FFat File system mounted
Total space: 13938688
Free space: 13938688
FlashChipSize: 16777216 (0x1000000)
ChipRevision: 3
14 MB free space on FFat
