BY25D80ASSIG from BOYAMICRO, in a SOP-8-208mil. 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 for the serial interface.
2 SO (IO1) bidirectional Serial Output for single bit data instructions; IO1 for Dual instructions.
3 /WP (IO2) input Write Protect input for single bit operation; listed as IO2 in the signal table.
4 VSS power_in Ground.
5 SI (IO0) bidirectional Serial Input for single bit data instructions; IO0 for Dual instructions.
6 SCLK input Serial Clock input.
7 NC unconnected No Connection.
8 VCC power_in Core and I/O power supply; VCC must be held stable within the specified VCC(min) to VCC(max) range during all operations (2.7 V to 3.6 V per the datasheet features).
