M24C01-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	E0	input	Chip Enable address input bit 0. Tied to VCC or VSS to set b1 of the 7-bit device select code (1010 E2 E1 E0). If left floating it is read as 0.
2	E1	input	Chip Enable address input bit 1. Tied to VCC or VSS to set b2 of the 7-bit device select code. If left floating it is read as 0.
3	E2	input	Chip Enable address input bit 2. Tied to VCC or VSS to set b3 of the 7-bit device select code. If left floating it is read as 0.
4	VSS	power_in	Ground reference for the device.
5	SDA	bidirectional	I2C Serial Data. Bidirectional open-drain line used to transfer data in and out of the device; must be pulled up to VCC through an external resistor sized against bus parasitic capacitance per Figure 5.
6	SCL	input	I2C Serial Clock input. Strobes all data in and out of the device. In systems that use slave clock stretching a pull-up to VCC is required and the master must be open-drain; otherwise a push-pull master needs no pull-up.
7	WC	input	Write Control (active-low, /WC). Driving High disables all write operations to the memory array (device-select and address bytes are still ACKed, data bytes are NoAcked). When left unconnected it is internally read as VIL and writes are enabled.
8	VCC	power_in	Supply voltage. For the 'W' voltage range (M24C01-W) the operating range is 2.5 V to 5.5 V. Decouple to VSS with a 10 nF to 100 nF capacitor placed close to the package.
