Microchip Tech · EEPROM · SOT-23-5
AT24C08C-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 command and input data on the SDA pin on its rising edge and clocks output data out on its falling edge; it 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, which should be connected to the system ground. |
| 3 | SDA | bidirectional | Open-drain serial data input/output that must be pulled high with an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices on the bus. |
| 4 | VCC | power_in | Device power supply pin; the device operates from 1.7 V to 5.5 V, and invalid VCC voltages may produce spurious results and should not be attempted. |
| 5 | WP | input | Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all writes to the protected (full) array; if left floating it is pulled down internally, and a pull-up of 10 kΩ or less is recommended. |
