FT24C256A-ETR-T from FMD Fremont Micro Devices, in a TSSOP-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 | A0 | input | Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected. |
| 2 | A1 | input | Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected. |
| 3 | A2 | input | Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected. |
| 4 | GND | power_in | Ground. |
| 5 | SDA | bidirectional | Serial data line, bi-directional with an open-drain output that can be wire-ORed and is typically pulled high by an external resistor. |
| 6 | SCL | input | Serial clock input where the rising edge latches data into the EEPROM and the falling edge clocks data out. |
| 7 | WP | input | Write protect input that allows programming when left unconnected or at VIL and disables all programming when connected to VIH or VCC, with reads unaffected. |
| 8 | VCC | power_in | Supply voltage, 1.8V to 5.5V. |
