AT24C04M5
HGSEMI · EEPROM · SOT-23-5
AT24C04M5 from HGSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCL | input | Serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-trigger filtered input. Requires an external pull-up to VCC. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | SDA | bidirectional | Serial data input/output. Open-drain; may be wire-ORed with other open-drain/open-collector devices. Requires an external pull-up resistor to VCC. |
| 4 | VCC | power_in | Supply voltage, 1.7V to 5.5V. Decouple locally to GND. |
| 5 | WP | input | Write protect. Tie to GND for normal read/write; tie to VCC to enable hardware write protection of the full array. |
