AT24C02D-STUM-T-TUDI

Tudi · EEPROM · SOT-23-5

AT24C02D-STUM-T-TUDI from Tudi, 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: data is positive-edge clocked into the device and negative-edge clocked out of it.
2 GND power_in Ground reference for the device.
3 SDA bidirectional Bidirectional open-drain serial data pin that may be wire-ORed with any number of other open-drain or open-collector devices.
4 VCC power_in Power supply; the datasheet specifies VCC of 1.7 V to 5.5 V at 400 kHz and 2.5 V to 5.5 V at 1 MHz.
5 WP input Write Protect: connecting to GND allows normal read/write operation, while connecting to VCC enables hardware write protection of the full array.
