Microchip Tech · EEPROM · SOT-23-5
24AA02T-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 reference for the device. |
| 3 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz), and changes only while SCL is low except for Start/Stop conditions. |
| 4 | VCC | power_in | Power supply; the 24AA02 operates from 1.7V to 5.5V. |
| 5 | WP | input | Write-protect input that must be tied to VSS to enable normal read/write of the full memory (00-FF) or to VCC to inhibit all write operations while leaving reads unaffected. |
