M95640-WMN6TP

STMicroelectronics · EEPROM · SOIC-8

M95640-WMN6TP from STMicroelectronics, in a SOIC-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: when driven high the device is deselected and Serial Data Output (Q) goes to high impedance (Standby Power mode unless an internal write is in progress); driving S low selects the device (Active Power mode) and a falling edge on S is required before any instruction after power-up.
2 Q output Serial Data Output: used to transfer data serially out of the device; data is shifted out MSB first on the falling edge of Serial Clock (C), and is high impedance when S is high or during Hold.
3 W input Write Protect: freezes the size of the memory area protected against Write instructions as set by the BP1/BP0 bits of the Status Register; must be driven high or low and held stable during all Write instructions, and together with the SRWD bit enables the Hardware Protected mode.
4 VSS power_in Ground: reference for all signals, including the VCC supply voltage.
5 D input Serial Data Input: used to transfer instructions, addresses and data to be written into the device; values are latched MSB first on the rising edge of Serial Clock (C).
6 C input Serial Clock: provides the timing of the serial interface (high-speed clock up to 20 MHz); input data on D is latched on the rising edge and output data on Q changes on the falling edge of this clock.
7 HOLD input Hold: used to pause serial communication with the device without deselecting it; while HOLD is low (with S already low and C low) Q is high impedance and D and C are Don't Care.
8 VCC power_in Supply voltage input, specified as 2.5 V to 5.5 V for the M95640-W device grade, which must remain stable within the valid operating range during all operations.
