24LC64-I from Microchip Tech, in a SOIC-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 | Chip Address Input 0; must be connected to VCC or VSS for slave device address configuration; up to eight devices may be connected to the same I2C bus using different chip select bit combinations. |
| 2 | A1 | input | Chip Address Input 1; must be connected to VCC or VSS for slave device address configuration; up to eight devices may be connected to the same I2C bus using different chip select bit combinations. |
| 3 | A2 | input | Chip Address Input 2; must be connected to VCC or VSS for slave device address configuration; up to eight devices may be connected to the same I2C bus using different chip select bit combinations. |
| 4 | VSS | power_in | Ground; common return path for the device. |
| 5 | SDA | bidirectional | Serial Data/Address bidirectional open-drain I/O pin used to transfer addresses and data; requires pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz operation). |
| 6 | SCL | input | Serial Clock input used to synchronize data transfer from and to the device at up to 400 kHz clock frequency. |
| 7 | WP | input | Write-Protect input; connect to VSS to enable write operations or to VCC to inhibit write operations while read operations remain enabled. |
| 8 | VCC | power_in | Power supply input; 2.5V to 5.5V operating range for 24LC64 Industrial temperature (-40°C to +85°C) devices. |
