24LC00T-I

Microchip Tech · EEPROM · SOT-23-5

24LC00T-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, with Schmitt Trigger input and noise-spike filtering on the SCL and SDA inputs.
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 (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz) and may change only while SCL is low for normal data transfer.
4 NC unconnected Not connected.
5 VCC power_in Power supply; the 24LC00 operates from 2.5 V to 5.5 V per the device selection table (the pin table gives +1.8 V to 5.5 V for the family).
