Microchip Tech · EEPROM · SOT-23-5
AT24C08D-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 clocks data to and from the device; commands and input data are latched on the rising edge of SCL and output data is clocked out on the falling edge, and 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, to be connected to 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 and may be wire-ORed with other open-drain or open-collector devices on the bus. |
| 4 | VCC | power_in | Device power supply pin for a source voltage of 1.7V to 3.6V; operation at invalid VCC voltages may produce spurious results. |
| 5 | WP | input | Write-protect input that allows normal writes when connected to GND and inhibits all writes to the full protected array when connected to VCC; it is internally pulled down to GND if left floating, but Microchip recommends driving it to a known state with a pull-up of 10 kΩ or less. |
