FT24C64A-ESR-T from FMD Fremont Micro Devices, in a SOP-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	A0	input	Device address input bit 0. Hardwire to VIH or VIL to set the chip select address; internally recognized as VIL if left unconnected.
2	A1	input	Device address input bit 1. Hardwire to VIH or VIL to set the chip select address; internally recognized as VIL if left unconnected.
3	A2	input	Device address input bit 2. Hardwire to VIH or VIL to set the chip select address; internally recognized as VIL if left unconnected.
4	GND	power_in	Ground reference for the device.
5	SDA	bidirectional	Serial data line. Bi-directional open-drain I/O for I2C data; requires external pull-up (typ. 1.3 kOhm to VCC per AC test conditions) and can be wire-OR'd with other open-drain devices.
6	SCL	input	Serial clock input. Data is latched on the rising edge and clocked out on the falling edge. Up to 1 MHz at 2.5-5V VCC, 400 kHz at 1.8V VCC.
7	WP	input	Write protect input. Programming is allowed when WP is unconnected or tied to VIL; all programming is disabled when WP is tied to VIH or VCC. Read operations are unaffected by WP.
8	VCC	power_in	Supply voltage, 1.8V to 5.5V. Absolute maximum 8V. Typical read/write current 0.4 mA / 2.0 mA at 5.0V; standby current <1 uA.
