M95128-DRDW3TP

STMicroelectronics · EEPROM · TSSOP-8

M95128-DRDW3TP from STMicroelectronics, in a TSSOP-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: driving it low selects the device and starts communication, driving it high deselects the device and puts Q in high impedance.
2 Q tri_state Serial Data output, shifts data out on the falling edge of Serial Clock (C) MSB first, and is high impedance in all other cases.
3 W input Write Protect, active low, used to write-protect the Status Register and must be driven high or low as appropriate.
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) MSB first.
6 C input Serial Clock, synchronizes the serial interface timing, with inputs latched on the rising edge and Q changing after the falling edge.
7 HOLD input Hold, active low, pauses serial communication with the device without deselecting it or resetting the clocking sequence.
8 VCC power_in Supply voltage, 1.7 V to 5.5 V for voltage range R (this MPN) with a 10 nF to 100 nF decoupling capacitor recommended close to VCC/VSS.
