# AT24C02CDBVRG

**HANSCHIP semiconductor** · EEPROM · SOT-23-5

AT24C02CDBVRG from HANSCHIP semiconductor, 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 for the 2-wire (I2C-compatible) bus. Command and input data on SDA are latched on the rising edge of SCL, while output data on SDA is clocked out on the falling edge. Schmitt-trigger, filtered input. |
| 2 | GND | power_in | Ground reference for the power supply. Must be connected to system ground. |
| 3 | SDA | bidirectional | Serial Data bidirectional pin for the 2-wire (I2C-compatible) bus. Open-drain output that requires an external pull-up resistor to VCC. Schmitt-trigger, filtered input. |
| 4 | VCC | power_in | Device power supply, 1.7V to 5.5V. Operations at invalid VCC voltages may produce spurious results. Bypass with a decoupling capacitor to GND. |
| 5 | WP | input | Write Protection input. When tied to VCC, the entire memory array becomes write-protected (device is read-only). When tied to GND, write operations are enabled. Internally pulled down to GND if left floating. |
