AT45DB041E-SSHN-T from Dialog Semiconductor Adesto Adesto Technologies, 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	SI	input	Serial Input (MOSI). Shifts command, address, and write data into the device. Data is latched on the rising edge of SCK; ignored when CS is deasserted.
2	SCK	input	Serial Clock. Provides the clock to the device; input data on SI is latched on the rising edge and output data on SO is clocked out on the falling edge. Supports up to 85 MHz.
3	RESET	input	Active-low hardware reset. Terminates any in-progress operation and holds the internal state machine in idle while low. Internal power-on reset makes external control optional; recommend driving high externally if unused.
4	CS	input	Active-low Chip Select. Falling edge starts an operation and rising edge ends it; when deasserted the device enters standby (SO is high-impedance).
5	WP	input	Active-low Write Protect. When asserted, all sectors specified in the Sector Protection Register are protected against program and erase, independently of any software protection. Internally pulled high; recommended to tie to VCC when not used.
6	VCC	power_in	Device power supply, 1.65 V to 3.6 V. Typical currents: 7 mA active read @ 15 MHz, 25 µA standby, 3 µA deep power-down, 400 nA ultra-deep power-down.
7	GND	power_in	Ground reference for the power supply. Connect to system ground.
8	SO	output	Serial Output (MISO). Shifts read data out of the device on the falling edge of SCK; high-impedance when CS is deasserted. Clock-to-output time (tV) 6 ns max.

AT45DB041E-SSHN-T

CAD (KiCad official)

Symbol: AT45DB041E-SSHN-T
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at45db041e-sshn-t.step`	122 KB	You want the bare part, or you mark your own boards.
`at45db041e-sshn-t-etched.step`	2.7 MB	You want the part with `AT45DB041E-SSHN-T` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 690 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.
