AT45DB041E-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 command, address, and data into the device on the rising edge of SCK. Ignored when CS is deasserted.
2	SCK	input	Serial Clock: provides the clock reference for the SPI interface. Input data on SI is latched on the rising edge; output data on SO is clocked out on the falling edge.
3	RESET	input	Reset (active low): a low state terminates the operation in progress and resets the internal state machine to idle. Internally pulled and features a power-on reset; recommended to be driven externally when used.
4	CS	input	Chip Select (active low): asserting CS selects the device. High-to-low transition starts an operation; low-to-high ends it. When deasserted, SO is high-Z and the device may enter standby.
5	WP	input	Write Protect (active low): when asserted, sectors specified for protection by the Sector Protection Register are protected against program/erase. Internally pulled high; recommended to be tied to VCC when not used.
6	VCC	power_in	Device power supply: 1.65V to 3.6V single-supply input for erase, program, and read operations.
7	GND	power_in	Ground reference for the power supply. Connect to system ground.
8	SO	output	Serial Output: shifts data out from the device, clocked on the falling edge of SCK. High-impedance whenever the device is deselected (CS high).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at45db041e-shn-t.step`	122 KB	You want the bare part, or you mark your own boards.
`at45db041e-shn-t-etched.step`	2.4 MB	You want the part with `AT45DB041E-SHN-T` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 631 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
