FC3379 QFN32 Minimum TSOP48 USB Flash Drive

Why this project:
The FC3379, a new generation of "garbage king" (meaning it can run all sorts of bad games with decent speed), comes in three packages, the smallest of which, QFN32, only has 1CE channel.
The reason for this project was that I had some old junk chips on hand, and upon disassembling them, I found they were 1CE TSOP TLC NAND flash memory. With the help of my "thinking power," this project was born (?). (A BGA152 version will be released later (procrastination). Some details
referenced from Lost-terminal's project : a double-layer board was used for faster prototyping and to avoid wasting 4-layer board resources (if it's free, cherish it). Because the USB reinforcement pins would interfere with the TSOP pads, the package was modified. When soldering, you need to bend it outwards a bit (for example, the silkscreen markings 3 and 2 on the board indicate VCC 3.3V and VCC 2.5V respectively). `v` is used to switch the VCC power supply of the NAND flash memory. An additional 0R resistor or wire connection is required. All other components can be removed from the original board. It's recommended to use TLC NAND flash if possible, as MLC NAND flash, according to LT, will significantly slow down speeds. (PS: The components are very cramped, which may cause considerable difficulty for those with less skill in soldering. Adding solder paste or using a hot plate may help.) You can also change the silkscreen to your preferred design, although there's not much space left. The speed is almost the same as the original board. (I don't know why the CDM write speed test is much slower than the actual speed.) Never use an ASSSD to run 4K, otherwise it will overload the 3379 firmware, causing a drastic speed drop, requiring a re-opening of the chip. The opening tool for the single-chip chip can be found on the official website: http://www.szfirstchip.com/col.jsp?id=142 FT64B08UCT2-08 (Jinshidun self-labeled Toshiba BICS5, single CE, 64G) full drive direct write speed is stable with no speed drop, occasionally fluctuating significantly. FT32B08CN1-47 (Jinshidun self-labeled B16A, single CE, 32G) full drive direct write speed is stable with no speed drop, almost a straight line (don't ask why the name is LostLabs because it was directly opened using LT's tools x).
