24LC32AT-I from Microchip Tech, in a SOIC-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 | Chip address input that must be driven to logic 0 or 1 (hard-wired to VCC or VSS) and is compared with the slave address bits to select the chip. |
| 2 | A1 | input | Chip address input that must be connected to either VCC or VSS and is compared with the slave address bits to select the chip. |
| 3 | A2 | input | Chip address input that must be connected to either VCC or VSS and is compared with the slave address bits to select the chip. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz), and may change only while SCL is low outside Start/Stop conditions. |
| 6 | SCL | input | Serial clock input that synchronizes data transfer to and from the device. |
| 7 | WP | input | Write-protect input that must be tied to VSS (write operations enabled) or VCC (write operations inhibited, read operations unaffected). |
| 8 | VCC | power_in | Power supply pin listed as +1.7V to 5.5V in the pin table; the 24LC32A is specified for 2.5V to 5.5V VCC in the Device Selection Table. |
