AT45DB081E-SHN-T from Dialog Semiconductor Adesto Adesto Technologies, 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	SI	input	Serial Input: shifts all data (commands, addresses, write data) into the device; latched on the rising edge of SCK and ignored while CS is deasserted.
2	SCK	input	Serial Clock: clocks the flow of data to and from the device; SI data is latched on the rising edge and SO data is clocked out on the falling edge; supports up to 85 MHz (1.7 V-3.6 V range).
3	RESET	input	Reset (active low): a low level terminates any operation in progress and holds the internal state machine in idle; normal operation resumes when the pin returns high; recommended to drive high if not used.
4	CS	input	Chip Select (active low): a high-to-low transition starts an operation and a low-to-high transition ends it; while deasserted the device is placed in standby mode and SO is high-impedance.
5	WP	input	Write Protect (active low): when asserted, protects all sectors specified in the Sector Protection Register against program and erase operations independent of software protection; internally pulled high and may be left floating if hardware protection is unused.
6	VCC	power_in	Device Power Supply: single supply voltage in the range 1.7 V to 3.6 V for all read, program, and erase operations.
7	GND	power_in	Ground: power-supply ground reference; must be connected to the system ground plane.
8	SO	output	Serial Output: shifts data out from the device on the falling edge of SCK; enters high-impedance state whenever CS is deasserted.
