M24256-DRDW8TP from STMicroelectronics, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | E0 | input | Chip enable input that sets the b1 bit of the 7-bit device select code; it must be tied to VCC or VSS, and when left floating it is read as low (0). |
| 2 | E1 | input | Chip enable input that sets the b2 bit of the 7-bit device select code; it must be tied to VCC or VSS, and when left floating it is read as low (0). |
| 3 | E2 | input | Chip enable input that sets the b3 bit of the 7-bit device select code; it must be tied to VCC or VSS, and when left floating it is read as low (0). |
| 4 | VSS | power_in | Ground, the reference for the VCC supply voltage. |
| 5 | SDA | bidirectional | Serial data I/O; an open-drain output that requires a pull-up resistor to VCC and may be wire-OR'ed with other open-drain or open-collector signals on the bus. |
| 6 | SCL | input | Serial clock input used to strobe data on SDA(in) and to output data on SDA(out). |
| 7 | WC | input | Write control input: driving it high disables write operations to the entire memory array (device select and address bytes are acknowledged, data bytes are not); driving it low or leaving it floating enables writes. |
| 8 | VCC | power_in | Supply voltage, 1.7 V to 5.5 V over the -40 °C to 105 °C range, to be decoupled close to the VCC/VSS pins (typically 10 nF to 100 nF). |
