AT24C01D-STUM-T

Microchip Tech · EEPROM · SOT-23-5

AT24C01D-STUM-T 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 latches SDA command and input data on its rising edge and must be forced high when the bus is idle or pulled high with an external pull-up resistor.
2 GND power_in Ground reference for the power supply that should be connected to the system ground.
3 SDA bidirectional Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 10 kΩ.
4 VCC power_in Device power supply pin operating from 1.7V to 3.6V, where invalid VCC voltages may produce spurious results.
5 WP input Write-protect input where connecting to VCC inhibits writes to the full array and connecting to GND allows normal writes, with any pull-up not exceeding 10 kΩ.

CAD (KiCad official)

  • Symbol: AT24C01D-STUM-T
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: at24c01d-stum-t-etched.step / at24c01d-stum-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c01d-stum-t.step / at24c01d-stum-t.glb are the bare package body.
