M95040-WDW6TP 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 | S | input | Active-low Chip Select; high deselects the device and puts Q in high impedance (standby), low selects it, and a falling edge is required after power-up before any instruction. |
| 2 | Q | tri_state | Serial Data Output that shifts data out on the falling edge of C and is high impedance when S is high or during the Hold condition. |
| 3 | W | input | Active-low Write Protect; when held low, writes to the memory are disabled, and it must be driven high or low and not left floating. |
| 4 | VSS | power_in | Ground, the reference for the VCC supply voltage. |
| 5 | D | input | Serial Data Input that receives instructions, addresses and data to be written, latched on the rising edge of C. |
| 6 | C | input | Serial Clock input providing the timing of the serial interface, with inputs latched on the rising edge and Q changing after the falling edge. |
| 7 | HOLD | input | Active-low Hold input that pauses serial communication without deselecting the device, with Q in high impedance and D and C don't care during Hold. |
| 8 | VCC | power_in | Supply voltage of 2.5 V to 5.5 V for the M950x0-W, to be held stable and decoupled with about 10 nF to 100 nF close to the VCC/VSS pins. |
