FT24C1024A-USR-B from FMD(Fremont Micro Devices), in a SOP-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 | NC | unconnected | No-connect pin with no internal function stated in the datasheet. |
| 2 | A1 | input | Device address input for chip select, typically hardwired to VIH or VIL and recognized as VIL if left unconnected. |
| 3 | A2 | input | Device address input for chip select, typically hardwired to VIH or VIL and recognized as VIL if left unconnected. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Serial data line, bi-directional with open-drain output that can be wire-ORed with other open-drain devices and needs an external pull-up resistor. |
| 6 | SCL | input | Serial clock input; rising edge latches data into the EEPROM and falling edge clocks data out. |
| 7 | WP | input | Write protect input; programming is allowed when left unconnected or at VIL and disabled when connected to VIH or VCC, while reads are unaffected. |
| 8 | VCC | power_in | Power supply, 1.8V to 5.5V. |
