W25Q128FVSIG from Winbond Elec, in a SOIC-8-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | /CS | input | Chip Select Input - active low control signal; device is selected for operation when /CS is low, deselected when high with serial data output pins in high impedance state. |
| 2 | DO (IO1) | bidirectional | Data Output / Data Input Output 1 - serial data output in standard SPI mode on falling edge of CLK; becomes bidirectional IO1 pin in Dual/Quad SPI modes when used for address or data I/O. |
| 3 | /WP (IO2) | bidirectional | Write Protect Input / Data Input Output 2 - active low hardware write protect input that prevents Status Register writes in standard and Dual SPI operation; becomes IO2 pin in Quad SPI when QE bit is set. |
| 4 | GND | power_in | Ground - power supply ground connection for 128M-bit serial flash memory. |
| 5 | DI (IO0) | bidirectional | Data Input / Data Input Output 0 - serial data input in standard SPI mode sampled on rising edge of CLK for instructions, addresses, and data; becomes bidirectional IO0 pin in Dual/Quad SPI modes. |
| 6 | CLK | input | Serial Clock Input - timing clock for serial input and output operations; supports DC to 104 MHz frequency for Fast Read and Quad instructions, DC to 50 MHz for Read Data (03h) instruction. |
| 7 | /HOLD or /RESET (IO3) | bidirectional | Hold or Reset Input / Data Input Output 3 - in Standard/Dual SPI with QE=0, active low hold input pauses device operation or reset input requires ≥1 µs low pulse; becomes IO3 pin in Quad SPI when QE bit is set. |
| 8 | VCC | power_in | Power Supply - supply voltage input operating range 2.7V to 3.6V required for device operation with active current 4 mA typical and standby current 10-50 µA. |
