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 address input bit b1 of the 7-bit I2C device select code. Must be tied to VCC or VSS (floating reads as 0). Sets one of eight device addresses on a shared bus. |+| 2 | E1 | input | Chip Enable address input bit b2 of the 7-bit I2C device select code. Must be tied to VCC or VSS (floating reads as 0). |+| 3 | E2 | input | Chip Enable address input bit b3 of the 7-bit I2C device select code. Must be tied to VCC or VSS (floating reads as 0). |+| 4 | VSS | power_in | Ground reference for VCC supply voltage. |+| 5 | SDA | bidirectional | I2C Serial Data input/output. Open-drain output, requires an external pull-up resistor to VCC. Transfers data in and out of the EEPROM synchronized with SCL. |+| 6 | SCL | input | I2C Serial Clock input. Strobes data available on SDA(in) and clocks out data on SDA(out). Supports up to 1 MHz on the -BW variant. |+| 7 | WC | input | Write Control (active low). When driven high, write operations to the entire memory array are inhibited (device select and address bytes are still acknowledged, data bytes are not). Driven low or left floating enables writes. |+| 8 | VCC | power_in | Supply voltage. On the -BW variant: 2.5 V to 5.5 V. Decouple with a 10 nF to 100 nF capacitor to VSS close to the package pins. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-8-150mil |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `M24256-BWMN6TPMN6TP`+- `M24256-BWMN6TPMN6`+- `M24256-BWMN6TPDW6TP`+- `M24256-BWMN6TPDW6`+- `M24256-BWMN6TPMC6TP`+- `M24256-BWMN6TPMC6`+- `M24256-BWMN6TPCS6`++## CAD (KiCad official)++- Symbol: `M24256-BWMN6TP`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/m24256-bwmn6tp.pdf) (43 pp, sha256 `3667ff5a4600a5b5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
