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.

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: at24c02cdbvrg-etched.step / at24c02cdbvrg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c02cdbvrg.step / at24c02cdbvrg.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HANSCHIP semiconductor datasheet (27 pp, sha256 30146010ee8ac6eb, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
