M95256-DRMN3TP

STMicroelectronics · EEPROM · SOIC-8

M95256-DRMN3TP 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 Active-low Chip Select. Driving S# low selects the device and starts SPI communication; driving it high deselects the device and forces the Q output into high impedance.
2 Q output Serial Data Output (MISO). Data is shifted out MSB-first on the falling edge of Serial Clock (C); high-impedance when the device is not selected.
3 W# input Active-low Write Protect. Used together with the BP bits in the Status Register to write-protect the Status Register (hardware protection).
4 VSS power_in Ground reference for all signals including VCC supply.
5 D input Serial Data Input (MOSI). Receives instructions, addresses and data, latched MSB-first on the rising edge of Serial Clock (C).
6 C input Serial Clock. Synchronizes the SPI interface; input data is latched on rising edges and output data changes on falling edges. Supports up to 20 MHz at VCC >= 4.5 V.
7 HOLD# input Active-low Hold. Pauses serial communication without deselecting the device; when low, Q goes high-impedance and D and C are ignored.
8 VCC power_in Supply voltage. Operating range 1.7 to 5.5 V for the R-grade device (M95256-DR). Decouple with a local bypass capacitor to VSS.
