AT24C02M5 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 | I2C Serial Clock input. Positive edge clocks data in and negative edge clocks data out. Schmitt-trigger, noise-filtered input. Requires an external pull-up to VCC (typically 1.3 kΩ at 2.5-5.5 V, 10 kΩ at 1.7 V). |
| 2 | Vss | power_in | Ground reference for the VCC supply. |
| 3 | SDA | bidirectional | I2C Serial Data input/output. Open-drain, may be wire-OR'ed with other open-drain devices. Requires an external pull-up to VCC. Data out has VOL ≤ 0.4 V @ IOL = 2.1 mA (VCC = 3.0 V). |
| 4 | Vcc | power_in | Supply voltage. Operating range 1.7 V to 5.5 V. Standby current ≤ 1 µA @ 3.3 V, ≤ 3 µA @ 5.5 V. Absolute maximum 6.5 V. |
| 5 | WCB | input | Write Control input, active low. Tie to VSS (or leave floating; internal pull-down to VSS) to allow normal write operations. Tie to VCC to inhibit all write operations and write-protect the entire memory array. |
