M95128-WMN6P

STMicroelectronics · EEPROM · SO-8

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.
