24LC024HT-I
Microchip Tech · EEPROM · SOIC-8
24LC024HT-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 | User-configurable chip address input that must be tied to VCC or VSS, used to select among up to eight devices on the same bus. |
| 2 | A1 | input | User-configurable chip address input that must be tied to VCC or VSS, used to select among up to eight devices on the same bus. |
| 3 | A2 | input | User-configurable chip address input that must be tied to VCC or VSS, used to select among up to eight devices on the same bus. |
| 4 | VSS | power_in | Ground. |
| 5 | SDA | bidirectional | Serial address/data I/O, open-drain, requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). |
| 6 | SCL | input | Serial clock input used to synchronize data transfer to and from the device. |
| 7 | WP | input | Hardware write-protect input that must be tied to VCC (protects half of the array, 80h-FFh) or VSS (write protection disabled). |
| 8 | VCC | power_in | Power supply, 2.5V to 5.5V for 24LC024H devices. |
