USB_FDD@1306
This is an adapter for using full-size 3.5" floppy drives as USB floppy drives. It uses an unknown 24-pin TSOP/TSSOP? microcontroller. The oscillator on the board is 12 mhz.
Chip pinout
| C4? | 1 | 24 | DIRECTION |
| LED? | 2 | 23 | VCC +5v |
| R3 | 3 | 22 | N/C |
| Drive Select | 4 | 21 | N/C |
| Motor On | 5 | 20 | Wgate |
| C3? | 6 | 19 | Write Protect |
| USB Data+ | 7 | 18 | Track 0 |
| USB Data- | 8 | 17 | DiskChange |
| RDATA | 9 | 16 | Index |
| WDATE | 10 | 15 | HeadSelect |
| VSS | 11 | 14 | STEP |
| OSC1 | 12 | 13 | OSC2 |
Note: It seems to use the sorta-compatible Shugart interface, as it uses pin 6 which is N/C in the IBM format.
for "Drive Select" it's hooked up to DS1/DS2/DS3/DS4.
