# HG24C02CM5

**HGSEMI** · EEPROM · SOT-23-5

HG24C02CM5 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 | 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. |
| 2 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 3 | SDA | bidirectional | Serial Data open-drain bidirectional input/output pin used to serially transfer data to and from the device. |
| 4 | VCC | power_in | Device power supply pin for a 1.7V to 5.5V supply; operation at invalid VCC voltages may produce spurious results. |
| 5 | WP | input | Write Protection input: connected to VCC the entire memory array becomes read-only, connected to GND writes are enabled, and if left floating it is internally pulled down to GND. |
