M95128-WMN6P 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 | S# | input | Chip Select (active low). When high, device is deselected and Q is high impedance; driving low selects the device and places it in Active power mode. A falling edge is required after power-up before any instruction. |
| 2 | Q | output | Serial data output (MISO). Data is shifted out on the falling edge of Serial clock (C). Enters high-impedance when chip is deselected or in Hold condition. |
| 3 | W# | input | Write Protect (active low). Freezes the memory area protected against Write instructions (as configured by BP1/BP0 in the Status register). Must be stable during all Write instructions. |
| 4 | VSS | power_in | Ground reference for all signals, including VCC supply voltage. |
| 5 | D | input | Serial data input (MOSI). Receives instructions, addresses and data bytes MSB first. Values are latched on the rising edge of Serial clock (C). |
| 6 | C | input | Serial clock (SCK). Provides timing for the SPI interface up to 20 MHz. Data on D is latched on the rising edge; data on Q changes on the falling edge. |
| 7 | HOLD# | input | Hold (active low). Pauses serial communications with the device without deselecting it. During Hold, Q is high impedance and D and C are don't care. Chip must be selected (S# low) to enter Hold. |
| 8 | VCC | power_in | Supply voltage. For M95128-W: 2.5 V to 5.5 V. Should be decoupled to VSS with a 10-100 nF capacitor placed close to the device pins. |
