24LC1025T-I from Microchip, in a SOIC-8-208mil. 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	A0	input	User-configurable chip-select address input bit 0. Compared against the corresponding bit in the slave address byte; the device responds only on match. Schmitt-trigger input; VIH = 0.7·VCC, VIL = 0.3·VCC (VCC>=2.5V). Hard-wire to VCC or VSS.
2	A1	input	User-configurable chip-select address input bit 1. Compared against the corresponding bit in the slave address byte; allows up to four 24XX1025 devices on the same bus. Schmitt-trigger input; must be tied to VCC or VSS.
3	A2	input	Non-configurable chip-select input. Must be hard-wired to VCC for normal operation; leaving it floating or tying it to VSS results in undefined operation. Selects the upper memory block internally.
4	VSS	power_in	Device ground reference (0V).
5	SDA	bidirectional	I2C serial data. Bidirectional open-drain terminal used to transfer addresses and data into and out of the device. Requires an external pull-up resistor to VCC (typ. 10 kΩ at 100 kHz, 2 kΩ at 400 kHz/1 MHz). Schmitt-trigger input with output slope control.
6	SCL	input	I2C serial clock input used to synchronize data transfer to and from the device. Schmitt-trigger input. Requires an external pull-up resistor to VCC.
7	WP	input	Hardware write-protect input. Tie to VSS to enable writes; tie to VCC to inhibit write operations (reads unaffected). Must be connected - do not leave floating. Schmitt-trigger input.
8	VCC	power_in	Supply voltage input. Operating range +2.5V to +5.5V for the 24LC1025 variant. Decouple with a local bypass capacitor to VSS. Standby current 5 µA max, read current 450 µA max at VCC=5.5V, SCL=400 kHz.
