24C256 from lingxingic 24C256 LX, 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. Combined with A1/A2 to hardware-address up to 8 devices on a single I2C bus. Internally pulled down to GND if left floating. |
| 2 | A1 | input | Device address input bit 1. Combined with A0/A2 to hardware-address up to 8 devices on a single I2C bus. Internally pulled down to GND if left floating. |
| 3 | A2 | input | Device address input bit 2. Combined with A0/A1 to hardware-address up to 8 devices on a single I2C bus. Internally pulled down to GND if left floating. |
| 4 | GND | power_in | Ground reference (0 V) for the device. |
| 5 | SDA | bidirectional | I2C serial data. Bidirectional, open-drain output; requires an external pull-up resistor (typically 4.7 kΩ to VCC). Can be wire-OR'd with other open-drain/open-collector devices. Input capacitance 8 pF max. |
| 6 | SCL | input | I2C serial clock. Data is latched into the EEPROM on the rising edge of SCL and clocked out on the falling edge. Supports 400 kHz (1.8-2.5 V VCC) and up to 1 MHz (2.5-5.5 V VCC). |
| 7 | WP | input | Write protect. When tied to GND, normal read/write operations are allowed. When tied to VCC, the entire 256K array is write-protected (hardware data protection). |
| 8 | VCC | power_in | Positive supply. Operating range 1.8 V to 5.5 V (absolute max 6.25 V). Typical operating current 0.2 mA read / 0.8 mA write at VCC=5.5 V, 400 kHz; standby current ≤3 µA at 5.5 V. |
