24AA02UIDT-I

Microchip Tech · EEPROM · SOT-23-5

24AA02UIDT-I from Microchip Tech, 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 synchronizes data transfer to and from the device on the 2-wire I2C-compatible bus, which supports 100 kHz and 400 kHz clock rates.
2 VSS power_in Ground reference for the device.
3 SDA bidirectional Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz).
4 VCC power_in +1.7V to 5.5V power supply.
5 NC unconnected Not connected.
