25LC010A-I from Microchip Tech, in a MSOP-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	CS	input	Chip Select input: a low level selects the device, and a high level deselects it and forces it into Standby mode, with a low-to-high transition after a valid write sequence starting the internal write cycle.
2	SO	tri_state	Serial data output: data is shifted out after the falling edge of SCK during a read, and SO goes to high-impedance when the device is deselected or HOLD is low.
3	WP	input	Hardware write-protect input: when low, all writes to the array and STATUS register are disabled while other operations function normally, and when high, nonvolatile writes operate normally.
4	VSS	power_in	Ground reference for the device.
5	SI	input	Serial data input that receives instructions, addresses and data, latched on the rising edge of the serial clock.
6	SCK	input	Serial clock input that synchronizes communication, latching SI on the rising edge and updating SO after the falling edge.
7	HOLD	input	Hold input that pauses serial communication when pulled low while SCK is low, must be held high when unused, and tri-states SO when lowered.
8	VCC	power_in	Supply voltage; the 25LC010A operates from 2.5V to 5.5V per the device selection table.
