BY25D40ASTIG

BOYAMICRO · NOR FLASH · SOP-8

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.
