25AA010AT-I from Microchip Tech, in a SOT-23-6. 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	SCK	input	Serial clock input that synchronizes host communication, latching instructions, addresses and data on SI at the rising edge and updating SO after the falling edge.
2	VSS	power_in	Ground.
3	SI	input	Serial data input that receives instructions, addresses and data, latched on the rising edge of the serial clock.
4	SO	tri_state	Serial data output that shifts data out after the falling edge of the serial clock and goes high-impedance when the device is deselected or HOLD is asserted.
5	CS	input	Chip select input where a low level selects the device and a high level deselects it into Standby mode with SO high-impedance.
6	VCC	power_in	Supply voltage, 1.8V to 5.5V for the 25AA010A (absolute maximum 6.5V).
