W25Q80DVSNIG TR from Winbond, in a SOIC-8. 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	Active-low SPI Chip Select input. Drive low to enable device access; when high the device is deselected and DO/IO pins are high-Z. /CS must track VCC at power-up (per power-up timing).
2	DO/IO1	bidirectional	Standard SPI serial data output (DO); in Dual/Quad SPI modes acts as bidirectional IO1. In Standard/Dual SPI this pin is DO; when QE=1 in Status Register-2 it becomes IO1 for Quad SPI.
3	/WP/IO2	bidirectional	Active-low hardware Write Protect input in Standard/Dual SPI, used with the Status Register Block Protect (CMP/SEC/TB/BP2/BP1/BP0) and SRP0 bits. Becomes bidirectional IO2 for Quad SPI when the Quad Enable (QE) bit is set.
4	GND	power_in	Device ground reference for all logic and I/O signaling.
5	DI/IO0	bidirectional	Standard SPI serial data input (DI); latched on rising edge of CLK. In Dual/Quad SPI acts as bidirectional IO0 for command, address, and data phases.
6	CLK	input	SPI Serial Clock input, up to 104 MHz. Provides timing for serial input/output; data on DI/IOx is latched on rising edge, data on DO/IOx is shifted out on falling edge.
7	/HOLD/IO3	bidirectional	Active-low Hold input in Standard/Dual SPI: while /CS is low, driving /HOLD low pauses the device with DO high-Z and DI/CLK ignored. Becomes bidirectional IO3 for Quad SPI when the Quad Enable (QE) bit in Status Register-2 is set.
8	VCC	power_in	Main power supply, 2.7V to 3.6V single-supply. Decouple with a local bypass capacitor to GND.
