MX25L25645GM2I-08G from MXIC Macronix, in a SOP-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	CS#	input	Chip Select, active-low. Drive low to enable the device for a command/data transaction; drive high to deselect the device and place it in standby.
2	SO/SIO1	bidirectional	Serial Data Output in single (1x) I/O mode; bidirectional serial data line SIO1 in 2x and 4x I/O modes. Data is shifted out on the falling edge of SCLK in single I/O.
3	WP#/SIO2	bidirectional	Hardware Write Protect (active-low) in 1x/2x I/O mode; also gates status-register writes with SRWD. In 4x I/O mode this pin becomes serial data line SIO2. Has an internal pull-up when not physically connected.
4	GND	power_in	Ground reference for the device (0 V).
5	SI/SIO0	bidirectional	Serial Data Input in single (1x) I/O mode; bidirectional serial data line SIO0 in 2x and 4x I/O modes. Data is latched on the rising edge of SCLK in single I/O.
6	SCLK	input	Serial Clock Input. All command, address and data bits are shifted on the SCLK edges (SPI Mode 0 and Mode 3 supported). Maximum frequency up to 133 MHz.
7	RESET#/SIO3	bidirectional	Hardware Reset input, active-low, in 1x/2x I/O mode; becomes bidirectional serial data line SIO3 in 4x I/O mode. Has an internal pull-up when not physically connected.
8	VCC	power_in	+3 V power supply. Operating range 2.7 V to 3.6 V for read, erase and program. Recommend decoupling with a 0.1 µF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mx25l25645gm2i-08g.step`	122 KB	You want the bare part, or you mark your own boards.
`mx25l25645gm2i-08g-etched.step`	3.5 MB	You want the part with `MX25L25645GM2I-08G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 849 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.
