M95128-RDW6TP

STMicroelectronics · EEPROM · TSSOP-8

M95128-RDW6TP 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: when high the device is deselected, Q is high impedance and the device is in Standby Power mode (unless a Write cycle is in progress); driving it low selects the device and a falling edge is required after power-up before any instruction.
2	Q	output	Serial Data Output: transfers data serially out of the device on the falling edge of Serial Clock (C), and is high impedance when deselected or during the Hold condition.
3	W	input	Write Protect: freezes the size of the memory area protected by the BP1 and BP0 bits of the Status Register, and 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, with inputs latched on the rising edge and Q changing from the falling edge, up to 20 MHz.
7	HOLD	input	Hold: pauses serial communications without deselecting the device; during Hold, Q is high impedance and D and C are Don't Care.
8	VCC	power_in	Supply voltage: 1.8 V to 5.5 V for M95128-R, must be held stable and within the valid range during all operations, with a 10 nF to 100 nF decoupling capacitor recommended close to the VCC/VSS pins.
