M95640-DRMN3TP

STMicroelectronics · EEPROM · SO-8

M95640-DRMN3TP 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 input; driving S low selects the device to start communication, driving it high deselects the device and puts Serial Data output (Q) into high impedance.
2 Q output Serial Data output used to shift data out of the device during a Read operation, MSB first, on the falling edge of Serial Clock (C); high impedance when not actively driving output.
3 W input Write Protect input used, in conjunction with the SRWD status-register bit, to write-protect the Status Register.
4 VSS power_in Ground pin; reference for all signals including the VCC supply voltage.
5 D input Serial Data input used to transfer instructions, addresses and write data into the device, latched MSB first on the rising edge of Serial Clock (C).
6 C input Serial Clock input that synchronizes the SPI interface; input data on D is latched on its rising edge and output data on Q changes after its falling edge, up to 20 MHz for VCC ≥ 4.5 V.
7 HOLD input Hold input used to pause serial communication without deselecting the device; when driven low with C low, Q goes high impedance and D/C are ignored until HOLD is driven high again.
8 VCC power_in Supply voltage pin; for this R/3 grade device VCC must be kept within 1.7 V to 5.5 V over the -40 °C to 125 °C operating range, decoupled close to the VCC/VSS pins.
