Microchip Tech · Pre-ordered Chips · SOT-23-5
24AA02HT-I from Microchip Tech, in a SOT-23-5. 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 | SCL | input | Serial Clock input used to synchronize data transfer to and from the device. |
| 2 | VSS | power_in | Ground. |
| 3 | SDA | bidirectional | Serial Address/Data I/O, open-drain bidirectional pin requiring a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). |
| 4 | VCC | power_in | Power supply, +1.7V to 5.5V. |
| 5 | WP | input | Write-Protect input that must be tied to VSS (normal operation of entire memory 00-FF) or VCC (write operations inhibited for upper half 80h-FFh, reads unaffected). |
