BY25D40ASTIG from BOYAMICRO, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | /CS | input | Chip Select input (I) used to select the device for serial operations. |
| 2 | SO (IO1) | bidirectional | Serial Output for single-bit data instructions and IO1 for Dual instructions (I/O). |
| 3 | /WP (IO2) | input | Write Protect input (I) in single-bit mode, enabling or disabling protection with the WP pin. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SI (IO0) | bidirectional | Serial Input for single-bit data instructions and IO0 for Dual instructions (I/O). |
| 6 | SCLK | input | Serial Clock input (I) that times serial data transfers. |
| 7 | NC | unconnected | No Connection; the pin is not connected internally. |
| 8 | VCC | power_in | Core and I/O power supply, which must be held stable within VCC(min) to VCC(max) during all operations; the datasheet gives 2.7 V to 3.6 V. |
