W25Q16JVZPIQ TR from Winbond Elec, in a WSON-8-EP(5x6). 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. Enables device operation when low; when high the device is deselected and DO/IOx pins are high-impedance. A pull-up resistor may be used to keep the pin high at power-up.
2	DO (IO1)	bidirectional	Data Output for Standard SPI (falling edge of CLK). In Dual/Quad SPI modes this pin becomes bidirectional data line IO1.
3	/WP (IO2)	bidirectional	Active-low Write Protect input in Standard/Dual SPI modes; prevents the Status Register from being written. Becomes bidirectional IO2 when Quad Enable (QE) bit is set for Quad SPI operation.
4	GND	power_in	Device ground reference.
5	DI (IO0)	bidirectional	Data Input for Standard SPI (rising edge of CLK). In Dual/Quad SPI modes this pin becomes bidirectional data line IO0.
6	CLK	input	SPI Serial Clock input providing timing for serial input and output operations. Supports SPI Modes 0 and 3 up to 133MHz.
7	/HOLD or /RESET (IO3)	bidirectional	Active-low /HOLD input (pauses device while selected) or optional /RESET input in Standard/Dual SPI modes. Becomes bidirectional IO3 when Quad Enable (QE) bit is set for Quad SPI operation.
8	VCC	power_in	Supply voltage input, 2.7V to 3.6V operating range.
