M95256-WMN6P

STMicroelectronics · EEPROM · SO-8

M95256-WMN6P from STMicroelectronics, in a SO-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 Chip Select, active low: high deselects the device and puts Q in high impedance (Standby unless a Write cycle is in progress), low selects it (Active Power mode); a falling edge is required after power-up before any instruction.
2 Q tri_state Serial Data Output, shifts data out on the falling edge of Serial Clock (C) and is high impedance when deselected or during the Hold condition.
3 W input Write Protect, active low: freezes the size of the memory area protected by the BP1 and BP0 bits of the Status Register, must be driven high or low and stable during all Write instructions.
4 VSS power_in Ground, the reference for all signals including the VCC supply voltage.
5 D input Serial Data Input, receives instructions, addresses and data to be written, latched on the rising edge of Serial Clock (C).
6 C input Serial Clock, provides the timing of the serial interface; inputs are latched on the rising edge and Q changes from the falling edge, with a maximum frequency of 20 MHz.
7 HOLD input Hold, active low: pauses serial communication without deselecting the device; during Hold Q is high impedance and D and C are Don't Care.
8 VCC power_in Supply voltage, 2.5 V to 5.5 V for M95256-W, which must be stable and valid during operation and write cycles; decouple with 10 nF to 100 nF close to the VCC/VSS pins.
