FT24C128A-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. Hardwired to VIH or VIL to set the chip's 3-bit slave address (matches bit 5 of the 8-bit device address word 1010_A2A1A0_RW). Internally pulled to VIL if left unconnected. |
| 2 | A1 | input | Device address input bit 1. Hardwired to VIH or VIL to set the chip's slave address. Internally recognized as VIL if left unconnected. |
| 3 | A2 | input | Device address input bit 2. Hardwired to VIH or VIL to set the chip's slave address. Internally recognized as VIL if left unconnected. |
| 4 | GND | power_in | Ground / VSS return for the device. |
| 5 | SDA | bidirectional | Serial data line for the 2-wire (I2C-compatible) bus. Open-drain bidirectional signal requiring an external pull-up resistor to VCC (typ. 1.3kΩ for AC characterization). Can be wire-ORed with other open-drain devices. |
| 6 | SCL | input | Serial clock input for the 2-wire bus. Rising edge latches data into the EEPROM; falling edge clocks data out. Schmitt-trigger, filtered input. |
| 7 | WP | input | Write Protect input. Tie to VIL (or leave unconnected) to allow programming of the EEPROM array; tie to VIH or VCC to disable all write operations. Read operations are unaffected by WP. |
| 8 | VCC | power_in | Positive supply voltage, 1.8V to 5.5V. Typical read current 0.4 mA and write current 2.0 mA at VCC = 5.0V, SCL = 100 kHz; standby current typically < 1µA. |
