# MX25L12833FM2I-10GTR

**MXIC Macronix** · NOR FLASH · SOP-8-208mil

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. |

## CAD (KiCad official)

- Symbol: `MX25L12833FM2I-10GTR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8-208mil (KiCad packages3D, STEP)
- 3D model files: `mx25l12833fm2i-10gtr-etched.step` / `mx25l12833fm2i-10gtr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mx25l12833fm2i-10gtr.step` / `mx25l12833fm2i-10gtr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`mx25l12833fm2i-10gtr.step`](mx25l12833fm2i-10gtr.step) | 122 KB | You want the bare part, or you mark your own boards. |
| [`mx25l12833fm2i-10gtr-etched.step`](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.
