HG24C02M5 from HGSEMI, 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 | The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | SDA | bidirectional | Bi-directional serial data pin; it is open-drain driven and may be wire-ORed with other open-drain or open-collector devices. |
| 4 | VCC | power_in | Power supply, 1.7 V to 5.5 V per the DC electrical characteristics. |
| 5 | WP | input | Write Protect: connecting the pin to GND allows normal read/write operations, while connecting it to VCC enables write protection of the array. |
