Microchip Tech · EEPROM · SOT-23-5
AT24C01D-STUM-T 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 that latches SDA command and input data on its rising edge and must be forced high when the bus is idle or pulled high with an external pull-up resistor. |
| 2 | GND | power_in | Ground reference for the power supply that should be connected to the system ground. |
| 3 | SDA | bidirectional | Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 10 kΩ. |
| 4 | VCC | power_in | Device power supply pin operating from 1.7V to 3.6V, where invalid VCC voltages may produce spurious results. |
| 5 | WP | input | Write-protect input where connecting to VCC inhibits writes to the full array and connecting to GND allows normal writes, with any pull-up not exceeding 10 kΩ. |
