M24256-BWMN6P from STMicroelectronics, in a SO-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 | E0 | input | Chip Enable 0 input; sets bit b1 of device select code; must be tied to VCC or VSS (reads low when floating). |
| 2 | E1 | input | Chip Enable 1 input; sets bit b2 of device select code; must be tied to VCC or VSS (reads low when floating). |
| 3 | E2 | input | Chip Enable 2 input; sets bit b3 of device select code; must be tied to VCC or VSS (reads low when floating). |
| 4 | VSS | power_in | Ground; reference for the VCC supply voltage. |
| 5 | SDA | bidirectional | Serial data input/output; open-drain output that may be wire-OR'ed with other signals; requires pull-up resistor to VCC. |
| 6 | SCL | input | Serial clock input; strobes data on SDA per I²C protocol; supports frequencies up to 1 MHz. |
| 7 | WC | input | Write control input; high disables write operations to memory array, low or floating enables write operations. |
| 8 | VCC | power_in | Supply voltage; 2.5 V to 5.5 V operating range for M24256-BW; requires 10-100 nF decoupling capacitor to VSS. |
