MX25L12833FM2I-10GTR 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. Enables/disables the device. All commands, address, and data transfers are framed by CS# being held low; CS# high puts the device in standby.
2	SO/SIO1	bidirectional	Serial Data Output (MISO) in Single I/O SPI mode; becomes bidirectional serial data line SIO1 in Dual I/O (2 x I/O) and Quad I/O (4 x I/O) read modes.
3	WP#/SIO2	bidirectional	Write Protect input (active low) in single/dual I/O modes, protects the Status Register when SRWD bit is set; becomes bidirectional serial data line SIO2 in Quad I/O (4 x I/O) read mode. Has an internal pull-up when not physically connected.
4	GND	power_in	Device ground reference (0 V).
5	SI/SIO0	bidirectional	Serial Data Input (MOSI) in Single I/O SPI mode; becomes bidirectional serial data line SIO0 in Dual I/O (2 x I/O) and Quad I/O (4 x I/O) read modes.
6	SCLK	input	Serial clock input. All SPI transactions are synchronous to this clock (SPI Mode 0 and Mode 3). Supports up to 133 MHz.
7	RESET#/SIO3	bidirectional	Hardware Reset input (active low) in single/dual I/O modes; becomes bidirectional serial data line SIO3 in Quad I/O (4 x I/O) read 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/program operations.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mx25l12833fm2i-10gtr.step`	122 KB	You want the bare part, or you mark your own boards.
`mx25l12833fm2i-10gtr-etched.step`	3.6 MB	You want the part with `MX25L12833FM2I-10GTR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 886 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.
