ZD24C08A-STGMT from Zetta, in a SOT-23-5. 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 | NC | unconnected | No Connect. On the 8K variant the device address pins A0/A1/A2 are not used (the three low bits of the device-address byte serve as memory page-address bits P0/P1 internally). Pin is not bonded to a die pad and may be tied to GND or left floating. |
| 2 | NC | unconnected | No Connect on the 8K variant (would be A1 on the 2K/4K versions). Not bonded to a die pad; may be tied to GND or left floating. |
| 3 | NC | unconnected | No Connect on the 8K variant (would be A0 on the 2K/4K/8K device-address bits). Not bonded to a die pad; may be tied to GND or left floating. |
| 4 | GND | power_in | Ground reference for the power supply. Connect to system ground (0 V). |
| 5 | SDA | bidirectional | Serial Data. Open-drain bidirectional I/O for the I2C-compatible 2-wire bus. Requires an external pull-up resistor to VCC (not to exceed 10 kΩ) and may be wire-ORed with other open-drain/open-collector devices on the same bus. |
| 6 | SCL | input | Serial Clock input. Provides the clock to the device; command/input data on SDA is latched on the rising edge and output data is clocked out on the falling edge. Must be held high when the bus is idle or pulled high via an external pull-up resistor. |
| 7 | WP | input | Write Protect (active high). Tying WP to GND enables normal read/write operations; tying WP to VCC inhibits all writes to the memory array (full-array protection). Internally pulled down to GND if left floating, though tying to a known state is recommended. |
| 8 | VCC | power_in | Device power supply input. Provides source voltage to the EEPROM; operation at invalid VCC levels may produce spurious results. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 589 faces against 102 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.
